Prices for Bacteriostatic Water start at £5.49 for the 10ml vial, and all of it is already in British stock at diluents.co.uk rather than sourced to order. There are 2 strengths to choose from (10ml, 30ml), offered as vial. Order on a weekday before 2pm and the parcel leaves that day, tracked, in a box that gives no clue to its contents.
Because the parcel never leaves the country, nothing has to clear customs, no import charge falls due and nothing is held at a border. Each batch tests at ≥99% by HPLC, and a certificate of analysis for the stock you receive is available on request.
Tracked delivery costs £4.95, or nothing above £75. The ordering steps, one by one.

Buying Bacteriostatic Water in the UK: where and how
How does ordering work?
Choose a strength, add it to the basket and go through checkout; no account is needed. An order confirmation comes through at once, and since the site never takes a card, the payment details arrive separately by email.
What difference does UK stock make?
Your Bacteriostatic Water is sent from a warehouse in Britain, so it skips customs, attracts no import charge and loses no days travelling from overseas. A courier collects it the same afternoon if the order is in before 2pm on a working day; the parcel then travels tracked in a plain outer box.
What do you receive?
| Purity | ≥99%, measured by HPLC |
|---|---|
| Labelling | Compound name, strength, format, purity and a research-use statement |
| Certificate of analysis | Available on request for the stock you receive |
| Delivery | UK addresses only, tracked. £4.95, or free over £75 |
| Returns | Within 14 days for sealed, unopened items, see the terms |
Bacteriostatic Water storage
| Vial, still sealed | Keep it dark, dry and cool; the freezer suits long-term storage best. |
|---|---|
| After mixing | Refrigerate it upright and shaded. A mixed solution should never be frozen. |
What is its shelf life?
| Condition | Typical life |
|---|---|
| Unopened, in a −20 °C freezer | Years. No other condition preserves a lyophilised peptide as well |
| Unopened, in a fridge at 2–8 °C | Months |
| Unopened, at room temperature | Weeks. It copes with the time in transit but should not be kept like this |
| Mixed, in the fridge | Weeks rather than months. With bacteriostatic water added, the usual working figure is four weeks, and making that possible is the job of its preservative |
| Mixed, then frozen | Not recommended. Peptides are torn by ice crystals, and each freeze–thaw cycle compounds the damage |
These are the standard figures for lyophilised peptides in general; no stability study on a single batch produced them. Time is gained by keeping it cold and dry, and lost to damp, warmth, light and rough handling. A certificate of analysis is available on request.
Is Bacteriostatic Water legal in the UK?
Here it is supplied strictly as an unlicensed compound for laboratory research use only. No UK marketing authorisation covers Bacteriostatic Water and it is not a licensed medicine, nor is it intended for human or veterinary use, or for food.
Compounds of this kind are not controlled drugs, and they can lawfully be sold as laboratory material; it is selling or marketing them for use by people that the law does not allow. That boundary is why this site carries no dose, protocol, route, frequency or medical claim, and why an emailed request for one is declined as well.
Some molecules in this range are also present in a licensed medicine marketed under a brand name. Its authorisation covers only the finished product for which it was granted, not the molecule in any other setting. Read the full terms.
