Description
Bacteriostatic Water (BAC Water): Sterile Reconstitution Solution for Research Use
Bacteriostatic Water (BAC Water) is a sterile, purified water solution containing 0.9% benzyl alcohol as a bacteriostatic agent. It is widely used in laboratory and research settings as a diluent and reconstitution vehicle for lyophilised (freeze-dried) compounds, including peptides and other research-grade substances.
Unlike standard sterile water for injection, Bacteriostatic Water is specifically formulated to inhibit bacterial proliferation, enabling repeated access to a single vial over an extended period without compromising sterility. This makes it the preferred reconstitution solution across research, compounding, and laboratory preparation workflows.
Key Features
- 0.9% Benzyl Alcohol: Acts as a bacteriostatic preservative, preventing bacterial growth and maintaining solution integrity between uses.
- Sterile and Purified: Produced under strict sterile manufacturing conditions. Each vial is free from particulates and microbial contamination prior to use.
- Extended Usability: Once opened, Bacteriostatic Water maintains its sterility for approximately 28 days, allowing multiple draws from a single vial.
- Sealed Vial System: Each vial features a gas-tight, clear sterile structure sealed with a pre-sterilised rubber septum (gamma-irradiated) and a centre tear-out crimp seal to preserve sterility until first use.
- Research Grade: Suitable for use as a reconstitution vehicle for lyophilised peptides, hormones, and other research compounds.
Research and Laboratory Applications
- Reconstitution of lyophilised peptides and research compounds
- Preparation of injectable solutions in laboratory settings
- Diluent for compounding and biological sample preparation
- Multi-use vial applications requiring repeated sterile access

Frequently Asked Questions
What is Bacteriostatic Water used for in research?
BAC Water is primarily used to reconstitute lyophilised (freeze-dried) research compounds, including peptides and hormones, into injectable solutions suitable for laboratory use.
Why is benzyl alcohol added to Bacteriostatic Water?
Benzyl alcohol at 0.9% concentration acts as a preservative that inhibits bacterial growth, allowing a single vial to be accessed multiple times without compromising sterility.
How long is Bacteriostatic Water stable after opening?
Once the vial has been accessed, the solution remains stable for approximately 28 days when stored correctly and handled with sterile technique.
Is Bacteriostatic Water the same as sterile water?
No. Standard sterile water for injection does not contain a preservative and is intended for single use only. Bacteriostatic Water contains 0.9% benzyl alcohol, which allows for repeated use from the same vial over a defined period.
Can Bacteriostatic Water be used to reconstitute all research peptides?
BAC Water is compatible with the majority of lyophilised research peptides. Researchers should verify compatibility with specific compounds prior to reconstitution, as some preparations may require alternative diluents.
