About the compound
What is Bacteriostatic Water 30ml?
Bacteriostatic water is sterile water that contains 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol suppresses the growth of bacteria, which allows a single vial to be accessed multiple times over a working period without the contents supporting microbial proliferation. Sova supplies it in 30 ml multi-dose vials as a laboratory reagent and solvent rather than an active compound.
In peptide research, bacteriostatic water is the standard solvent used to reconstitute lyophilised peptides supplied as dry powder. Adding the solvent dissolves the powder into a stable working solution, and the benzyl alcohol content helps limit contamination during repeated withdrawals from the same vial. Its mild preservative action makes it the common choice over plain sterile water for multi-use research preparations.
Because it is a reagent rather than a receptor-active compound, bacteriostatic water has no pharmacological pathway of its own. Its role in the laboratory is functional: providing a preserved aqueous medium for dissolving and holding research peptides. Researchers select it when a reconstituted preparation will be sampled repeatedly, since the benzyl alcohol restrains bacterial growth across the working life of the vial.
Sova's bacteriostatic water UK stock is supplied in sealed, sterile 30 ml multi-dose vials manufactured to be free of viable microorganisms, with the 0.9% benzyl alcohol content providing ongoing bacteriostatic protection. Store vials sealed at room temperature, away from light, and keep the stopper intact between withdrawals. Sova dispatches domestically within the UK. This reagent is supplied strictly for laboratory research use only and not for human or veterinary use.

FAQ
Bacteriostatic Water 30ml, answered.
What is bacteriostatic water?
+
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, a preservative that suppresses bacterial growth. This lets a single vial be accessed multiple times during a working period. Sova supplies it in 30 ml multi-dose vials as a laboratory reagent and solvent.
Is bacteriostatic water legal to buy in the UK?
+
Yes. Bacteriostatic water is supplied in the UK as a laboratory reagent for research use only. It is not sold for human or veterinary use. Purchasers are responsible for handling it appropriately within a research setting.
What is bacteriostatic water used for?
+
In the laboratory, bacteriostatic water is the standard solvent for reconstituting lyophilised research peptides supplied as dry powder. The benzyl alcohol content limits contamination during repeated withdrawals, making it suitable for research preparations that are sampled multiple times from one vial.
Is Sova's bacteriostatic water sterile?
+
Yes. It is supplied in sealed, sterile 30 ml multi-dose vials produced to be free of viable microorganisms, and the 0.9% benzyl alcohol provides ongoing bacteriostatic protection. Keeping the stopper intact between withdrawals helps maintain integrity across the working life of the vial.
How should bacteriostatic water be stored?
+
Store sealed vials at room temperature, away from direct light. Refrigeration is generally unnecessary while sealed. Keep the rubber stopper intact between withdrawals and observe the manufacturer's in-use period, handling the vial under standard laboratory practice to preserve its bacteriostatic properties.
How does bacteriostatic water differ from sterile water?
+
Both are sterile, but bacteriostatic water contains 0.9% benzyl alcohol whereas plain sterile water contains none. The preservative lets bacteriostatic water be accessed repeatedly from one vial, while unpreserved sterile water is intended for single use, as it offers no ongoing protection against bacterial growth.
