Best Bacteriostatic Water for Research 2026
The best bacteriostatic water for research 2026 is a critical component in various laboratory applications, including peptide reconstitution, lyophilization, and cell culture. Bacteriostatic water is defined as water that contains a bacteriostatic agent, such as 0.9% benzyl alcohol, which prevents the growth of microorganisms. For research-grade supply, see BAC Water Depot's 10 mL vial catalog.
Characteristics of the Best Bacteriostatic Water for Research 2026
The best bacteriostatic water for research 2026 should meet certain criteria, including ISO 9001:2015 certification, US manufacturing, and third-party lab testing. The water should be sterile, non-pyrogenic, and have a low endotoxin level. Additionally, the water should be packaged in a Type I borosilicate glass vial, which is resistant to thermal shock and chemical corrosion. BAC Water Depot's bacteriostatic water meets these criteria, with a Certificate of Analysis (CoA) provided for each lot. For more information on the importance of CoA, visit our knowledge base.

Applications of Bacteriostatic Water in Research
Bacteriostatic water has various applications in research, including peptide reconstitution, cell culture, and lyophilization. Peptide reconstitution requires the use of bacteriostatic water to prevent the growth of microorganisms, which can contaminate the peptide and affect its activity. Cell culture also requires the use of bacteriostatic water to prevent the growth of microorganisms, which can contaminate the cell culture and affect the results. Lyophilization, also known as freeze-drying, requires the use of bacteriostatic water to prevent the growth of microorganisms, which can contaminate the lyophilized product and affect its stability.

People Also Ask
What is the difference between bacteriostatic water and sterile water?
Bacteriostatic water is water that contains a bacteriostatic agent, such as 0.9% benzyl alcohol, which prevents the growth of microorganisms. Sterile water, on the other hand, is water that has been sterilized to remove all microorganisms. While both types of water are used in research, bacteriostatic water is preferred for certain applications, such as peptide reconstitution and cell culture.
What is the shelf life of bacteriostatic water?
The shelf life of bacteriostatic water depends on the storage conditions and the type of packaging used. Generally, bacteriostatic water has a shelf life of 2-3 years when stored at room temperature and 5-6 years when stored at refrigerated temperatures.
Can I use bacteriostatic water for human or veterinary use?
No, bacteriostatic water is not intended for human or veterinary use. It is only intended for research and laboratory use.
What is the concentration of benzyl alcohol in bacteriostatic water?
The concentration of benzyl alcohol in bacteriostatic water is typically 0.9%.
How do I store bacteriostatic water?
Bacteriostatic water should be stored at room temperature or refrigerated temperatures, depending on the type of packaging used. It should be protected from light and moisture.
