About this peptide

Bacteriostatic Water

Sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative, for reconstituting lyophilised research material.

  • 01 Multi-puncture diluent

    The 0.9% benzyl alcohol suppresses microbial growth, which is what allows a vial to be drawn from more than once.

  • 02 Twenty-eight day window

    The preservative's effectiveness declines after repeated punctures. The 28-day clock starts at the first puncture of the stopper, not at first use.

  • 03 Non-pyrogenic

    Supplied sterile and endotoxin-tested, so it does not introduce contaminants into a reconstituted preparation.

  • 04 Not a peptide

    Listed alongside the catalogue as a laboratory consumable. It carries no peptide content and no certificate of analysis for identity or purity.

FAQ

Before you order.

Anything not covered here, ask us directly — replies within one working day.

Is a COA included with my order?
Yes. Every vial ships with a certificate of analysis tied to the lot number printed on its label, covering identity by mass spectrometry and purity by HPLC. Retained samples are held so a batch can be re-tested.
How is the product shipped?
Lyophilised powder is stable at ambient temperature in transit and ships in discreet, tracked packaging. UK and EU orders are sent on a priority service; international destinations are quoted at checkout.
How should the vial be stored on arrival?
Keep it sealed at −20°C, protected from light. Lyophilised material is stable for months under those conditions. Once reconstituted, store at 2–8°C and use within the window stated on the certificate of analysis.
Who is this product for?
Qualified researchers and laboratories only. It is supplied strictly as an analytical and in-vitro research material, and is not a medicine, a supplement or a veterinary product.
What is the difference between bacteriostatic and sterile water?
Sterile water contains nothing but water and has no preservative, so a vial is single-use. Bacteriostatic water contains 0.9% benzyl alcohol, which suppresses microbial growth and allows repeated withdrawals for up to 28 days.
Does this ship with a certificate of analysis?
No. It is a diluent rather than a peptide, so there is no identity or purity assay to certify. Sterility and non-pyrogenicity are covered by the manufacturer's release documentation.
