Bacteriostatic Water – 0.9% benzyl alcohol
Bacteriostatic Water is a sterile, non-pyrogenic water solution containing 0.9% (9 mL/L) benzyl alcohol as a bacteriostatic preservative. It is supplied in a multi-dose 10 mL, 30 mL vials, or 1 L and is intended to dilute or dissolve research reagents that require an aqueous vehicle before use. The benzyl alcohol inhibits bacterial growth, allowing repeated withdrawals within up to 28 days under appropriate aseptic handling. pH typically falls within 4.5–7.0. Not for clinical use; Research Use Only (RUO).
Bacteriostatic Water for Peptide and Protein Reconstitution
Many peptides, proteins and other biological reagents are supplied in lyophilized form and must be reconstituted before use.
Where a reconstituted research reagent will be accessed repeatedly, bacteriostatic water provides an alternative to preservative-free sterile water. The inclusion of 0.9% benzyl alcohol helps inhibit bacterial growth following repeated vial puncture.
Typical applications include:
- Reconstitution of compatible lyophilized research peptides
- Reconstitution of compatible recombinant proteins
- Preparation of research reagent stock solutions
- Reconstitution of biological standards and controls
- Multidose laboratory preparations
- Further manufacturing of research products
Compatibility with the particular peptide, protein or other reagent should always be confirmed before use. Benzyl alcohol may not be suitable for every biological molecule or experimental application.
Why Choose Canvax Bacteriostatic Water?
Manufactured in Europe
Canvax manufactures the product at its own facilities in Valladolid, Spain.
This provides an alternative to bacteriostatic water sourced through resellers or from manufacturers outside Europe.

Need Bacteriostatic Water in Larger Quantities?
Canvax is the original manufacturer, rather than simply a reseller of the finished product.
Through You Do Bio we can therefore also discuss requirements beyond standard laboratory packs, including:
- Larger quantities
- Custom fill volumes
- Alternative vial or packaging formats
- Custom specifications
- Additional QC requirements
- OEM/private-label production
- Custom labelling
- Bulk supply
- Further-manufacturing applications
Canvax has extensive liquid-manufacturing and filling capabilities for research, diagnostic and biomanufacturing customers.
Bacteriostatic Water vs Sterile Water
The main difference is the presence of an antimicrobial preservative.
Sterile water contains no bacteriostatic preservative and may therefore be preferred when preservative-free reconstitution is required.
Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits microbial growth and makes it suitable for compatible research preparations that require repeated aseptic withdrawals.
The correct diluent depends on the molecule, formulation and experimental application. Always follow the instructions associated with the reagent being reconstituted.
Frequently Asked Questions
What is bacteriostatic water?
Bacteriostatic water is sterile water containing an antimicrobial preservative. This Canvax product contains 0.9% benzyl alcohol.
What does the benzyl alcohol do?
Benzyl alcohol inhibits microbial growth following initial puncture of a multidose vial, allowing repeated aseptic withdrawals over an extended period.
How much benzyl alcohol does the product contain?
The concentration is 0.9%, equivalent to 9 mg/mL benzyl alcohol.
Can bacteriostatic water be used to reconstitute peptides?
Bacteriostatic water is commonly used for reconstitution of compatible lyophilized research peptides.
However, the appropriate diluent depends on the individual peptide and formulation. Always verify compatibility with the peptide manufacturer’s recommended reconstitution conditions.
Can bacteriostatic water be used for proteins and antibodies?
It may be suitable for some proteins and other biological reagents, but benzyl alcohol can affect the stability of certain proteins. Compatibility should therefore be confirmed for the particular protein and experimental application.
How long can an opened vial be used?
Canvax specifies an in-use period of up to 28 days after the first puncture, provided appropriate aseptic handling is used.
Is Canvax Bacteriostatic Water sterile?
Yes. The product is specified as sterile and non-pyrogenic and is manufactured using 0.22 µm filtration followed by aseptic filling.
Is this Bacteriostatic Water for Injection?
No.
Canvax E0328 Bacteriostatic Water is supplied for Research Use Only or Further Manufacturing. It is not intended for injection, direct administration to humans or animals, diagnostic use or therapeutic use.
Is bulk or OEM bacteriostatic water available?
Yes. Canvax manufactures liquid reagents in-house and can discuss larger-scale, custom-filled and OEM/private-label requirements.
