Frequently Asked Questions
Common Research Questions
What is BAC Water?
BAC water, or bacteriostatic water, is sterile water containing 0.9% benzyl alcohol as a preservative. It is used in laboratory settings to reconstitute peptides and other research compounds. The benzyl alcohol inhibits bacterial growth in multi-dose vials. BAC water maintains sterility for repeated withdrawals over time. It is a standard solvent in peptide preparation protocols.
Does BAC Water need to be refrigerated?
BAC water does not require refrigeration for short-term use but is often stored in the refrigerator to extend stability. Unopened vials should be kept at room temperature, as freeze thawing, could result in the stability being damaged or reconstitution failure. Proper storage reduces contamination risk in research environments.
How long does BAC water last?
Unopened bacteriostatic water typically has a shelf life of 1-2 years from the manufacture date when stored properly. After opening, it is commonly used for 28 days in laboratory practice. Discard if cloudiness, particles, or contamination appears. The benzyl alcohol concentration maintains bacteriostatic properties during this period.
Is reconstitution solution the same as bacteriostatic water?
Reconstitution solution often refers to bacteriostatic water in peptide research contexts. However, some protocols use sterile water without preservative for single-use applications. Bacteriostatic water is preferred for multi-dose vials due to the preservative. Sterile saline or other buffers may also serve as reconstitution solutions depending on the compound.
