Diluents and consumables
Bacteriostatic water — sterile water with 0.9% benzyl alcohol — is the standard laboratory diluent for reconstituting lyophilized reference peptides in multi-draw vials. The preservative suppresses bacterial growth so a vial can be sampled across a working interval rather than once.
Why it ships separately
Diluent is not included with reference compounds. Different protocols call for different diluent volumes and, in some cases, different diluents entirely, so the choice belongs to the laboratory rather than the supplier.
Handling
Store sealed at room temperature away from light. Wipe the stopper with isopropyl alcohol before each draw and introduce diluent slowly against the vial wall — never as a jet into the lyophilized cake.
Supplies — FAQ
- Are these compounds sold for human use?
- No. Every compound in this catalog is supplied strictly as a reference material for in-vitro laboratory research. They are not drugs, supplements, or cosmetics, and they are not for human or animal administration.
- What purity standard applies?
- Every batch is analyzed by reverse-phase HPLC at ≥98% purity, confirmed for identity by mass spectrometry, quantitatively assayed for content, and screened for heavy metals. Batch-specific third-party certificates are published on each product page.
- Is bacteriostatic water included?
- No. Diluent is supplied separately and is listed under Supplies. Bacteriostatic water (0.9% benzyl alcohol) is the standard laboratory diluent for multi-draw reference vials.
- How should material be stored on arrival?
- Lyophilized reference compounds are kept sealed and refrigerated at 2–8 °C for short-term working stock, or frozen at −20 °C or colder for long-term archive. Once reconstituted, solution is refrigerated, protected from light, and treated as a consumable.
