Buy Bacteriostatic Water in Northern Ireland
Bacteriostatic water (often shortened to BAC water ) is sterile water containing 0.9% benzyl alcohol — the standard diluent used to reconstitute lyophilised research peptides into solution. The benzyl alcohol is bacteriostatic, meaning it suppresses microbial growth, so a reconstituted multi-use research vial stays stable across repeated laboratory draws over several weeks under refrigeration. New-U supplies USP-grade bacteriostatic water in sealed 3 ml and 10 ml vials, in full 10-vial research packs.

What is Bacteriostatic Water?
Bacteriostatic water (often shortened to BAC water ) is sterile water containing 0.9% benzyl alcohol — the standard diluent used to reconstitute lyophilised research peptides into solution. The benzyl alcohol is bacteriostatic, meaning it suppresses microbial growth, so a reconstituted multi-use research vial stays stable across repeated laboratory draws over several weeks under refrigeration. New-U supplies USP-grade bacteriostatic water in sealed 3 ml and 10 ml vials, in full 10-vial research packs.
How Bacteriostatic Water is used in the lab
In the lab, bacteriostatic water is the reconstitution medium of choice for almost every lyophilised peptide: the powder is dissolved by adding a measured volume of BAC water, and the 0.9% benzyl alcohol keeps the resulting stock solution free of bacterial growth across repeated handling — unlike plain sterile or preservative-free water, which is single-use. Working out the volume is a simple concentration calculation (volume = mass ÷ target concentration); 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
Every batch of New-U bacteriostatic water is USP-grade and sterility-assured, filled into sealed, tamper-evident vials with batch traceability. We ship it direct in full 10-vial packs (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 Northern Ireland — FAQ
Bacteriostatic water (BAC water) is sterile water with 0.9% benzyl alcohol added as a bacteriostatic preservative. It is the standard diluent for reconstituting lyophilised research peptides, and the preservative lets a reconstituted vial be drawn from repeatedly over several weeks. Supplied for laboratory and research use only — not for human use.
Plain sterile water carries no preservative, so it is single-use — once opened it must be discarded. Bacteriostatic water contains 0.9% benzyl alcohol, which suppresses microbial growth and lets a reconstituted multi-use research vial stay stable across repeated draws. For multi-use vials, bacteriostatic water is the standard choice.
Thanks to the benzyl alcohol preservative, an opened vial of bacteriostatic water is typically usable for around 28 days when stored refrigerated and handled with sterile technique. Always follow the batch label and your own laboratory protocols.
It depends on the peptide mass and the stock concentration you want for your study — it is a simple calculation (volume = mass ÷ target concentration). 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+.
