Bacteriostatic Water 10 ml

Bacteriostatic Water 10 ml — the reconstitution standard for multi-withdrawal laboratory work
Sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The preservative is what separates it from ordinary sterile water: it inhibits bacterial growth after the vial has first been entered, which is what makes repeated withdrawals from a single vial possible under proper aseptic technique.

What is bacteriostatic water?

Bacteriostatic water is sterile, non-pyrogenic water for injection to which a bacteriostatic agent has been added — in this case benzyl alcohol at 0.9%. Plain sterile water is single-use by nature: once the stopper is pierced, there is nothing to prevent microbial proliferation in what is otherwise an ideal growth medium. The benzyl alcohol addresses that directly, giving the vial a usable service life across multiple entries and making it the default diluent wherever a reconstituted preparation needs to be drawn more than once.

Where it is used

• Reconstitution of lyophilised material — the standard diluent for returning freeze-dried powders to solution, according to the instructions of the product being prepared.
• Dilution — used to bring concentrated preparations to a working concentration.
• Multi-withdrawal work — the bacteriostatic agent supports repeated access to a single vial when strict aseptic technique is observed.
• General laboratory preparation — a clean, preservative-stabilised aqueous base free of the particulates and ionic content of non-pharmaceutical water.

Note that benzyl alcohol is not compatible with every preparation; some compounds are specified for use with plain sterile or unpreserved water. Always defer to the instructions supplied with the product being reconstituted.

Specifications

• Presentation: Sealed, tamper-evident single vial
• Storage: Cool, dry place, protected from light; do not freeze

Handling & storage

Store at controlled room temperature in a cool, dry place away from direct light. Do not freeze. Before use, inspect the vial: the solution must be clear and colourless, free of visible particulates, and the vial itself intact with its seal undamaged. Discard any vial showing cloudiness, discolouration or a compromised stopper. Once opened, follow the storage and in-use period specified by the manufacturer of the product with which it is being used, and always employ proper aseptic technique when accessing the vial.

Why researchers buy from Rogue

• Batch-tested, not batch-guessed — purity and identity verified before a vial is ever listed.
• Authentic European sourcing — a short, controlled supply chain with sealed, tamper-evident vials.
• Consistency across orders — lot-to-lot control so repeat work stays comparable.
• Fast, tracked, discreet — quick EU-wide dispatch in unmarked packaging.
