Buy Bacteriostatic Water in Wales

Bacteriostatic water (often shortened to BAC water ) is sterile water containing 0.9% benzyl alcohol - a laboratory diluent used when reconstituting lyophilised research compounds where the applicable protocol permits its use. The benzyl alcohol is bacteriostatic: it inhibits bacterial growth after a vial has been punctured, which is what distinguishes it from preservative-free sterile water. It does not sterilise contamination or make the vial usable indefinitely. New-U supplies USP-grade bacteriostatic water in sealed 3 ml and 10 ml vials, in full 10-vial research packs.

The benzyl alcohol is bacteriostatic: it inhibits bacterial growth after a vial has been punctured, which is what distinguishes it from preservative-free sterile water.

How Bacteriostatic Water is used in the lab

In the lab, bacteriostatic water is one reconstitution option for lyophilised compounds that are compatible with an aqueous vehicle and with benzyl alcohol. The powder is dissolved by adding a measured volume of BAC water when the documentation or protocol allows it; preservative-free sterile water, saline or another solvent may be required instead. Working out the volume is a simple concentration calculation (concentration = mass ÷ volume); New-U's free reconstitution calculator computes it for any peptide. Supplied strictly as a laboratory consumable for research use.

Why labs choose New-U Bacteriostatic Water

New-U bacteriostatic water is manufactured or supplied to the stated USP-grade specification, filled into sealed, tamper-evident vials with batch traceability. Peptide HPLC certificates do not verify accessory water quality. We ship it direct as single-vial samples and 10-vial research packs where listed (3 ml and 10 ml) so a lab keeps enough diluent on hand for a complete run of reconstitutions - no single-vial mark-ups and no relabelled stock.

Buying Bacteriostatic Water in Wales - FAQ

Bacteriostatic water (BAC water) is sterile water with 0.9% benzyl alcohol added as a bacteriostatic preservative. It is a laboratory diluent for reconstituting lyophilised research compounds where the protocol permits its use. The preservative inhibits bacterial growth after puncture but does not sterilise contamination. Supplied for laboratory and research use only - not for human use.

Both begin sterile at manufacture. Plain sterile water carries no preservative and is generally single-use. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits microbial growth and supports repeated withdrawal when the label permits multi-dose use. Choose the diluent specified by the compound documentation or experimental protocol.

Follow the product manufacturer’s instructions. Where no different period is provided, punctured multi-dose vials are commonly discarded within 28 days under CDC guidance, and that date must not extend past the original expiry. Storage temperature is also label-specific - some official products specify controlled room temperature rather than mandatory refrigeration.

It depends on the peptide mass and the stock concentration required by the study - concentration = mass ÷ volume. Our free reconstitution calculator works out the volume for any peptide. New-U provides this as a math utility only, not as dosing guidance.

Yes - "bac water" or "bac" is the everyday shorthand researchers use for Bacteriostatic Water. New-U supplies Bacteriostatic Water strictly as a research compound for laboratory and research use only - not for human use. 21+.
