What is Bacteriostatic Water ?
Bacteriostatic Water for Injection is sterile non-pyrogenic water that contains 0.9% benzyl alcohol (9mg/mL), which is added as a bacteriostatic preservative.
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.
This preparation of sterile water and benzyl alcohol (BnOH) allows repeated withdrawals to be made from a single 30mL plastic vial. Hospira, the world’s leading manufacturer and supplier of bacteriostatic and sterile water, recommends that once a vial of bacteriostatic water is open the preservatives will prolong its life for up to 28 days and that after this period of time the vial should to be discarded. Other sterile waters for injection without the bacteriostatic agent (single-dose vials) should be discarded after a single use. Visit our page to purchase online at wholesale supply prices.
The semi-rigid vial is fabricated from a specially formulated polyolefin. It is a copolymer of ethylene and propylene. The safety of the plastic has been confirmed by tests in animals according to USP biological standards for plastic containers. The container requires no vapor barrier to maintain the proper labeled volume.
DOSAGE AND ADMINISTRATION
The volume of the preparation to be used for diluting or dissolving any drug for injection is dependent on the vehicle concentration, dose and route of administration as recommended by the manufacturer.
