Description
BAC – Bacteriostatic Water is specially prepared sterile water used in scientific laboratories. It contains 0,9 % benzyl alcohol, which acts as a preservative and allows repeated withdrawal of small quantities during laboratory experiments. This water is used primarily for rehydrating lyophilised substances and for other experimental procedures where sterility and solution stability are important.
Research interest and scientific focus:
Bacteriostatic Water is a standard solution used in laboratory experiments. It is essential for preparing peptide solutions and cell cultures, stability testing, sample rehydration and handling sensitive substances. Scientific teams frequently use it in tissue research, biochemistry and cell experiments.
How BAC is discussed in the community:
In the laboratory and biochemistry community, BAC is considered a fundamental tool for working with peptides and lyophilised substances. Users particularly value its sterility, reliability for repeated use and versatile role in preparing experimental solutions. It is often described as a “must-have” product in research setups.
