Bacteriostatic water is a great product for any researcher. Unlike normal, sterile water, bacteriostatic water can be used multiple times in a 28-day period. Regular sterile water is single use and must be discarded after opening.
Many scientists use bacteriostatic water in their experiments. This type of water for injection is a non-pyrogenic water that contains 0.9% benzyl alcohol, which acts as a bacteriostatic agent. This makes it so bacteria cannot grow, which is why it can be used over and over again throughout a month.
