# Bacteriostatic water UK buy?

Sable Peptides sells bacteriostatic water (10 ml) for laboratory reconstitution of lyophilised research peptides, shipped next-day in the UK. It is a laboratory diluent sold for research use only, not for injection or human use, and is priced under the same daily-checked lowest UK price guarantee.

Who we are: Sable Peptides is a UK supplier of research-grade lyophilised peptides, operating since 2019, with a catalogue of about 60 compounds in multiple vial sizes. Everything is sold for in-vitro laboratory research only. Nothing is a medicine, and we give no usage advice.

Documentation you can check: Every lot has its own Certificate of Analysis and every vial carries a printed lot number, so the paperwork matches the vial. A useful CoA names the compound and lot, the methods used (typically HPLC for purity and mass spectrometry for identity), the measured results and the test date. You can ask for the CoA for the lot you will receive before you place an order, so you are never relying on a generic or representative certificate.

Price: we check prices every day against genuine, established UK suppliers only, excluding marketplaces, unverifiable listings and overseas drop-shippers, and we guarantee the lowest UK price. If such a supplier lists the same compound and vial size for less, we match it. Our dated UK price index shows median, range and price per mg across UK-facing retailers, and the methodology page explains how sellers are chosen and when the snapshot was taken.

Delivery and payment: orders ship next-day across the UK. Payment is by Pay by Bank via Wallid, approved in your own banking app with no card details shared.

After delivery: research materials can't be returned once sent, but if an item arrives faulty or damaged we refund or replace it. Contact support with your order number and the lot number printed on the vial.
