TECHNICAL SPECIFICATIONS

PRODUCT OVERVIEW

A research-use-only supply of a 10 mL research sample storage case is a laboratory organizational accessory designed for use in controlled research and laboratory environments specifically for the physical organization, positional stabilization, and environmental segregation of sealed 10 mL research-grade sample containers under defined storage conditions. These cases represent secondary or tertiary packaging: they do not contact the research compound directly, do not form part of the validated container–closure system determining barrier properties, and are not subject to product-approval pathways. They are scientific infrastructure tools, not medical devices.

The primary construction material is polypropylene (PP, 1-propene homopolymer, CAS 9003-07-0), manufactured by chain-addition polymerization of propylene monomer (CAS 115-07-1, PubChem CID 8252). Published laboratory materials research indicates that polypropylene exhibits lower peptide adsorption relative to standard borosilicate glass surfaces for certain hydrophobic peptide classes — making polypropylene case construction specifically relevant to the peptide research ecosystem where container-surface interactions are documented in primary literature (Bhatt et al., Int. J. of Peptides 2012; PMC3290000). Case shell construction from laboratory-grade polypropylene aligns with material science expectations for research packaging.

In the 2026 U.S. research sciences ecosystem, demand for citation-backed packaging infrastructure resources for laboratory operations has increased substantially. Profound Aminos references the 10 mL research sample storage case exclusively within a scientific education and laboratory infrastructure framework — not as a consumer-accessible substance-delivery system.

USE APPLICATIONS – 2026 RESEARCH CONTEXT

In the 2026 U.S. research sciences ecosystem, the 10 mL research sample storage case (PP-10) is referenced as laboratory packaging infrastructure for the following controlled research organizational applications:

1. Freezer-Compatible Research Container Organization (−25°C to −10°C)
   

   The primary use application for 10 mL research sample storage cases in peptide and biological research laboratory settings is organized freezer storage of sealed research-grade sample containers. The freezer storage condition of −25°C to −10°C is the standard long-term storage range for lyophilized peptide research reagents, including RUO peptidomimetics, GLP-1 analogues, and growth factor analogs requiring cold preservation between laboratory preparation sessions. Polypropylene construction enables full thermal compatibility with this range (PP retains structural integrity and low-brittleness characteristics at −25°C), while the multi-position slot design prevents container-to-container mechanical impact and positional displacement during freezer access. Storage-condition compliance is a foundational requirement for maintaining research-compound integrity; organized container storage supports documentation and lot segregation for institutional research programs.

2. Refrigerator-Compatible Peptide Research Reagent Workflow Support (+2°C to +8°C)
   In peptide research settings where solution-form research reagents, short-term GLP-1 research compound stocks, or thawed lyophilized compounds are maintained at refrigerator temperature (+2°C to +8°C), the 10 mL research sample storage case provides an organizational substrate that keeps labeled containers in defined positions accessible during experimental workflow. Polypropylene’s thermal stability and low moisture uptake eliminate condensation-induced label adhesion failure during refrigerator access.. Research by Bhatt et al. (Int. J. of Peptides 2012; PMC3290000) documents that container material selection influences adsorption profile for hydrophobic peptide sequences — a materials-science consideration informing case selection in peptide laboratory infrastructure planning. The case organizer enables clear visual segregation of multiple research compounds within a shared refrigerator environment, supporting good laboratory practice (GLP) documentation and preventing cross-compound cross-contamination of sealed containers.
   Reference: Bhatt DL et al., Int. J. of Peptides 2012; PMC3290000.
3. Controlled Room Temperature Sample Organization and Lot Segregation (+20°C to +25°C)
   For research compounds specified for controlled room temperature (CRT) storage (+20°C to +25°C, with mean kinetic temperature ≤ 25°C), the 10 mL research sample storage case functions as a bench-top or cabinet organizer enabling lot segregation and multi-position organization in laboratory workspaces. Research programs conducting parallel investigations with multiple lot numbers, multiple analogue compounds, or comparative research reagent sets require documented lot separation — a practice supported by multi-position organizer cases that enable position-specific labeling.
   Polypropylene cases at CRT conditions eliminate any thermal stress concerns and offer maximum shelf stability. This application is particularly relevant for reference standard management in peptide sequence verification workflows, where multiple RUO research compounds in sealed containers may be maintained at CRT per supplier CoA specifications.
4. Multi-Compound Research Workflow Organization in Qualified Laboratory Settings
   In active research laboratory settings investigating multiple peptide research reagents simultaneously — for example, parallel PHB/ANXA2 receptor characterization experiments across multiple research compounds (Adipotide/FTPP, PTP-r, PBP-NP control peptides), or comparative GLP-1 analogue research programs — the 10 mL research sample
   The storage case provides the organizational substrate for defined container positioning that supports experiment documentation, reagent chain-of-custody tracking, and visual inventory management. Multi-position case design allows color-coded or position-mapped container organization systems that complement institutional research program SOPs and IACUC/IBC documentation requirements. All compound handling within a qualified laboratory setting remains governed by institutional procedures, supplier Certificates of Analysis, and applicable IACUC, IBC, and biosafety review requirements.Reference: IACUC documentation standards. Kolonin MG et al., Nat Med 2004 (PHB/ANXA2 research reference context).
5. Cold-Transport Tertiary Packaging Support for Sealed Research Containers
   For research programs requiring physical transport of sealed 10 mL research sample containers between laboratory locations — including inter-facility transfer of qualified research reagents under institutional procedures — the 10 mL research sample storage case provides tertiary packaging protection: physical cushioning, positional stability, and impact resistance for sealed primary container–closure systems during transport. Tertiary components protect against mechanical and environmental stress during transit without contacting the research compound directly. Polypropylene cases with latching or zippered closures prevent accidental separation during transport; internal compartmentalization prevents container-to-container impact that could displace closures. All transport of research compounds must comply with applicable institutional biosafety, IATA, and carrier regulations for the specific research compound class being transported. These cases do not qualify as validated cold-chain devices and do not independently maintain temperature; supplementary cold-pack systems and insulated carriers are required for temperature-sensitive cold-chain transport.

6. GLP-1 Research Reagent and Biological Sample Storage Infrastructure
   In the 2026 U.S. peptide research ecosystem, GLP-1 research compounds (GLP-1-Sm analogues, GLP/GIP-Tz research references, GLP/GIP/GLC-Rt research tools) maintained as qualified research reagents in research laboratory settings are typically stored in sealed 10 mL containers under refrigerator or controlled room temperature conditions per supplier CoA. The 10 mL research sample storage case provides the organizational infrastructure for these workflows: multi-position labeled container management, freezer/refrigerator shelf organization, and lot segregation. All labeling, accessory product descriptions, and marketing content in the GLP-1 and peptide research ecosystem should frame organizational accessories as laboratory infrastructure without clinical implication.

WHY SOURCE FROM PROFOUND AMINOS 

1. Material Identity Transparency — CAS-Anchored Polymer Reference
   Profound Aminos identifies all featured laboratory infrastructure products by primary construction material, CAS number, and PubChem monomer reference: 10 mL research sample storage case construction material — polypropylene (1-propene homopolymer); CAS 9003-07-0; PubChem monomer CID 8252. This chemical identity transparency enables researchers and compliance professionals to cross-reference supplier material data sheets, verify polymer grade against plastic packaging standards, and confirm material identity against authoritative registry databases before laboratory procurement. Accessory content without CAS anchoring and packaging-framework documentation leaves research procurement documentation incomplete and YMYL compliance exposure unaddressed in the 2026 Google search environment.
2. Packaging Framework Compliance — Secondary Packaging Standards Documentation
   Every Profound Aminos laboratory infrastructure reference integrates applicable packaging framework documentation: packaging and storage requirements (secondary/tertiary classification), plastic packaging systems (PP material compliance reference), and auxiliary packaging components. This packaging anchoring provides a defensible compliance reference for both research documentation and content publishing — critical for YMYL compliance in the 2026 Google search environment where unverified claims are subject to elevated algorithmic scrutiny under the E-E-A-T quality framework applied to all laboratory infrastructure content.
3. FDA/FTC Regulatory Compliance Framing — Laboratory Infrastructure Positioning
   Profound Aminos maintains strict content discipline separating laboratory packaging infrastructure descriptions from clinical or self-administration language.

FREQUENTLY ASKED QUESTIONS

Q1: What is a 10 mL research sample storage case and what are its key material identifiers?

A 10 mL research sample storage case — also designated PP-10 or a polypropylene multi-position laboratory organizer — is a laboratory infrastructure component constructed to hold multiple sealed 10 mL research-grade sample containers in organized, positionally stable arrangements within controlled storage environments. The primary construction material is polypropylene (1-propene homopolymer), CAS 9003-07-0. PubChem provides a structural reference for the propylene monomer (1-propene, CAS 115-07-1) under CID 8252 (SMILES: C=CC, formula C3H6, MW ≈ 42.08 g/mol) — the structural repeat unit whose chain-addition generates the polypropylene backbone. These cases function as secondary or tertiary packaging components, separate from the primary container–closure system of the sealed research containers they organize.

Q2: What is polypropylene’s relevance to peptide research laboratory infrastructure and container compatibility?

Polypropylene’s relevance to peptide research laboratory infrastructure is documented in primary literature. Bhatt et al. (Int. J. of Peptides 2012; PMC3290000) established that hydrophobic peptide adsorption profiles differ between borosilicate glass and polypropylene contact surfaces — with polypropylene demonstrating lower non-specific adsorption for certain hydrophobic peptide sequences compared to standard glass surfaces. This materials science finding contextualizes the preference for polypropylene labware in peptide research settings where adsorption-related compound loss could affect experimental consistency. While a 10 mL storage case does not directly contact the research compound (the compound is sealed within its primary container–closure system), the material compliance of the polypropylene case aligns with expectations for laboratory packaging materials in a research environment.

Q3: Which packaging standards are relevant to 10 mL laboratory storage case selection?

Three primary packaging topics are relevant to 10 mL laboratory storage case selection in peptide research settings. Packaging and storage requirements define the packaging hierarchy (primary, secondary, tertiary), storage condition categories (freezer: −25°C to −10°C; refrigerator: +2°C to +8°C; controlled room temperature: +20°C to +25°C; cool; controlled cold), and the expectation that packaging systems not interact with product in ways affecting identity, strength, quality, or purity. Plastic packaging systems and their materials of construction provide the material compliance framework for plastic packaging components including polypropylene (CAS 9003-07-0). Auxiliary packaging components address secondary and tertiary packaging accessories — the category under which 10 mL research sample storage cases fall. These topics collectively establish the reference framework for laboratory packaging infrastructure assessment in the U.S. research market.

Q4: What temperature storage ranges does a polypropylene 10 mL research sample storage case support?

Polypropylene (1-propene homopolymer, CAS 9003-07-0) maintains structural integrity across a temperature range of approximately −25°C to +100°C in standard labware grades, fully spanning common storage condition categories for research compounds: freezer (−25°C to −10°C), refrigerator (+2°C to +8°C), cool (+8°C to +15°C), controlled cold (+2°C to +15°C, mean kinetic temperature ≤ +8°C), controlled room temperature (+20°C to +25°C), and room temperature (+15°C to +30°C). Specific thermal data should be verified against the case supplier’s product data sheet. The case itself does not maintain temperature — it is a passive organizational accessory. Supplementary cold-chain systems (insulated carriers, cold packs, refrigerant gel packs) are required for any temperature-sensitive transport application. All storage conditions for specific research compounds remain governed by the supplier’s Certificate of Analysis.

Q5: Is a 10 mL research sample storage case a device or combination product?

A 10 mL research sample storage case, positioned and marketed solely as a laboratory organizational accessory for sealed research containers, is not a device or combination product. It has no product-approval pathway — it is a commodity laboratory labware item. Such cases function as secondary or tertiary packaging: they do not contact the research compound, do not affect research compound properties, and are not part of the validated primary container–closure system.

The FDA’s enforcement focus in the peptide and GLP-1 market targets the research compounds themselves and the marketing content framing them — not neutral organizational accessories described accurately in materials-science terms. However, the FDA Objective Intent Doctrine (21 CFR 201.128) requires that all accessory product content, imagery, and marketing avoid language implying preparation or use of unapproved compounds for human use. Framing storage cases as laboratory infrastructure within materials-science and packaging-standard content is the appropriate regulatory posture.

Q6: What is the PubChem reference for polypropylene, and how should it be used in research content?

Polypropylene as a high-molecular-weight polymer does not have a single small-molecule PubChem CID in the way that a peptide or small molecule does — the polymer chain is structurally variable and lacks a single molecular identity. The standard authoritative approach is to anchor polypropylene reference content to its monomer: propylene (1-propene, CAS 115-07-1), which carries PubChem CID 8252 (SMILES: C=CC, formula C3H6, MW ≈ 42.08 g/mol, 2D structural diagram available at pubchem.ncbi.nlm.nih.gov/compound/8252). This monomer-level PubChem image, captioned as ‘Polypropylene (1-propene homopolymer) — structural repeat unit reference — CAS 9003-07-0’ and linked to the PubChem record, satisfies the expectation of PubChem-anchored structural imagery for laboratory material reference content in the 2026 Google E-E-A-T framework. The NIST WebBook also provides complementary polymer-level data for polypropylene referenced via CAS 9003-07-0.

Q7: How does the polypropylene 10 mL storage case compare to glass rack and aluminum case alternatives for research peptide container organization?

Polypropylene 10 mL research sample storage cases are used in peptide research laboratory applications alongside glass rack and aluminum case formats. Relative to borosilicate glass racks: polypropylene provides higher impact resistance — glass rack fragility creates contamination risk if broken in freezer or laboratory environments; polypropylene also demonstrates lower surface adsorption for hydrophobic peptide sequences per Bhatt et al. (PMC3290000), relevant where accidental container-surface contact might occur. Relative to aluminum cases: polypropylene offers lower density (≈0.9 g/mL vs. ≈2.7 g/mL for aluminum), reduced weight for repeated freezer-access workflows; polypropylene also eliminates oxidation/corrosion concerns that emerge with aluminum in humid freezer environments. For visual identification, polycarbonate cases offer higher optical transparency; polypropylene cases require position-labeling systems for container identity management. Selection should be based on specific laboratory requirements, storage environment conditions, and institutional procurement standards.

Q8: What FDA and Google compliance considerations apply to accessories marketed in the peptide research ecosystem?

In the 2026 U.S. peptide research market, accessory products — including 10 mL storage cases marketed alongside research peptide compounds — are assessed under converging compliance frameworks. A product’s intended use is established by the totality of its labeling, marketing, and adjacent content — not just the product itself. Accessory item descriptions that contribute to an ecosystem of non-research use create compliance exposure. Under Google’s 2026 E-E-A-T/YMYL framework, laboratory accessory content on peptide science platforms is evaluated for expertise, trustworthiness, and accuracy — pages combining accessory products with implicit or explicit preparation language for research compounds face de-ranking under the March and May 2026 Core Updates. The compliant approach: describe storage cases in materials-science terms (packaging framework, polymer CAS, thermal range), cite authoritative sources, and explicitly exclude preparation or administration language for research compounds.
