BAC-Wasser 10 ml

Specification

Function and properties

BAC Water 10 ml is sterile, pyrogen-free water containing 0.9% benzyl alcohol. The alcohol acts as a bacteriostatic preservative: it inhibits the growth of microorganisms that can be introduced when a multi-dose vial is repeatedly punctured. The product is supplied as a laboratory reagent and serves as the aqueous base for preparing ready-to-use solutions. Its consistent composition from batch to batch makes it a reproducible starting material for laboratory test series. Researchers who buy BAC Wasser use this 10-vial kit as a defined reference for in-vitro work.

Handling and first use

Handle the vial aseptically: clean the port before each use and puncture it only with sterile equipment. After the first opening, the contents remain usable for up to 28 days when aseptic technique is maintained. Keep the vial closed between withdrawals and protect it from direct light so that the solution stays clear and free of visible particles. Discard the solution if cloudiness or particles appear.

In-vitro research

In in-vitro research, BAC Water 10 ml serves as a solvent for the reconstitution of lyophilized laboratory reagents. The powder is taken up in the sterile medium according to the protocol of the laboratory performing the work, yielding a ready-to-use solution. The volume depends on the individual study design and is recorded in the laboratory protocol. The bacteriostatic action supports the stability of the prepared solution across multiple withdrawals, which simplifies work with standardized setups in cell culture and comparable in-vitro models.

Quality and analytics

Each batch of BAC Water 10 ml is tested for sterility and pyrogen content according to USP. The composition, with 0.9% benzyl alcohol as the preservative, is documented for every batch. Testing covers the finished product rather than a single vial: all vials in a box come from the same batch and carry the same documented content. The tests are completed before the batch is released, and the results are recorded for that batch.
