bacteriostatic water 20ml – Laboratory Grade Sterile Diluent

bacteriostatic water 20ml is a sterile, non-pyrogenic preparation of water for injection containing 0.9% (9 mg/mL) benzyl alcohol added as a bacteriostatic preservative. This 20ml multi-dose vial format is manufactured specifically for in vitro research applications, analytical standard preparation, and laboratory reagent solubilization where sterility maintenance across multiple withdrawals is required.

Each milliliter of bacteriostatic water 20ml contains:

The benzyl alcohol component suppresses bacterial growth without acting as a true bactericide, allowing the bacteriostatic water 20ml to maintain sterility for up to 28 days after initial penetration when stored under appropriate conditions. This preservation mechanism is critical for research environments requiring multiple access events from a single container.

Every batch of bacteriostatic water 20ml undergoes comprehensive analytical validation:

Independent third-party laboratory verification is provided via Certificate of Analysis (COA) with each bacteriostatic water 20ml unit. Safety Data Sheets (SDS) documenting hazard classification, handling protocols, and emergency procedures are available for download.

bacteriostatic water 20ml serves as a fundamental laboratory reagent across multiple analytical disciplines:

Analytical Chemistry: Diluent preparation for HPLC mobile phases, spectrophotometric standards, and chromatographic sample reconstitution where aqueous solubility and sterility are required.

Biochemistry: Reagent hydration for enzyme assays, protein dilution buffers, and immunological test systems requiring preserved aqueous media.

Microbiology: Culture media preparation, serial dilution blanks, and reagent reconstitution in controlled laboratory environments.

Cell Culture: While not classified as tissue culture grade, bacteriostatic water 20ml may serve as a diluent for non-therapeutic analytical procedures following appropriate validation.

Store bacteriostatic water 20ml at controlled room temperature (15-30°C). Protect from freezing and direct sunlight. Once accessed, maintain vial integrity and use within 28 days. Discard if visible particulate matter, cloudiness, or discoloration is observed. Do not use beyond the expiration date stamped on the container.

The 20ml multi-dose presentation minimizes waste in research settings requiring multiple small-volume withdrawals compared to single-use ampoules. The rubber stopper design permits repeated sterile needle access when aseptic technique is employed.

bacteriostatic water 20ml is supplied as a laboratory chemical for research purposes only. It is not manufactured, labeled, or intended for therapeutic administration, injection into humans or animals, or clinical diagnostic applications. The benzyl alcohol preservative is contraindicated for certain research applications including neonatal studies—consult your institutional safety protocols.

Each bacteriostatic water 20ml vial is labeled with:

Australian domestic supply ensures 1-3 business day delivery to metropolitan centers, minimizing transit time and thermal exposure risk. All shipments include insulated packaging and temperature monitoring during transit.

bacteriostatic water 20ml is available to verified research institutions, analytical laboratories, and qualified scientific professionals. Account verification and institutional affiliation may be required prior to shipment. Bulk pricing available for quantities exceeding 10 units.
