Bacteriostatic Reconstitution Water (BAC)
FAQ's
What is BAC water used for in peptide research?
BAC water is used as a sterile diluent to reconstitute peptides before use in research. It prevents bacterial growth and prolongs the viability of the mixed solution.
Is bacteriostatic water the same as peptide mixing water?
Yes, bacteriostatic water is commonly referred to as peptide mixing water in research, as it’s ideal for dissolving peptides before lab use.
How does BAC water compare to sterile water for injection?
BAC water contains 0.9% benzyl alcohol, making it multi-use for up to 28 days, unlike sterile water which is single-use only and lacks preservatives.
How do you reconstitute peptides with BAC water?
Use a sterile syringe to draw the appropriate volume of BAC water and slowly inject it into the peptide vial. Gently swirl until fully dissolved. Do not shake.
Why does BAC water contain benzyl alcohol?
Benzyl alcohol at 0.9% acts as a bacteriostatic agent, preventing the growth of bacteria in the solution and extending its usability.
How long is BAC water good for after opening?
BAC water is viable for up to 28 days after the first use, as long as proper sterile technique is maintained.
Can BAC water be used for all peptides?
Most peptides used in laboratory research are compatible with BAC water, but always check specific peptide solubility before mixing.
Is BAC water safe for human use or injection?
No. Real Peptides BAC Water is for research purposes only and is not intended for human or animal injection or therapeutic use.
Where can I buy high-quality BAC water for peptides?
You can order lab-grade BAC water from Real Peptides, shipped in sealed, sterile 10ml vials ideal for research applications.
How should I store BAC water after use?
Keep BAC water stored in a cool, dry place, ideally between 36°F–77°F (2°C–25°C). Avoid contamination by using sterile handling practices.
