Research background

About Sterile Water

It is also the diluent of choice where a sterile-filled finished preparation builds its preservation system into the formulation rather than the diluent. It is supplied as a characterized ancillary diluent rather than a research-target molecule.

Medabol supplies SWFI in sterile vial formats to USP Water for Injection monograph specifications; sterility and bacterial endotoxin (LAL) results are available on request and listed on the batch COA when tested; EP / BP / JP equivalents are available on request. Because there is no preservative, an opened vial has a limited multi-use life (microbial ingress after septum puncture is the limiting factor), so SWFI is matched to single-use or short-window preparation. Match the diluent to the peptide's stability profile: acidic-pH-requiring peptides use the 0.6% acetic-acid diluent; preservative-incompatible peptides use SWFI; preservative-compatible peptides for multi-use can use BAC Water.

For laboratory research use. This page describes published research and the material we supply; it is not medical advice.

Sterile Water FAQ

Why is SWFI the preferred diluent for benzyl-alcohol-incompatible peptides?

Benzyl alcohol (the preservative in BAC Water) associates with the surface of some short peptides, which can shift solubility, accelerate aggregation, or interfere with benzyl-alcohol-sensitive downstream assays. Preservative-free SWFI removes that concern entirely, at the trade-off that the opened vial must be used within a short window because nothing inhibits microbial growth after septum puncture. For documented benzyl-alcohol-compatible peptides, BAC Water is operationally simpler; for new or untested peptides, SWFI is the conservative default.

What pharmacopeia specification applies to SWFI?

Medabol supplies SWFI to the USP Water for Injection monograph (strict limits for total organic carbon, conductivity, microbial limits, and bacterial endotoxin); sterility results are available on request and listed on the batch COA when tested. International equivalents (EP, BP, JP) are available on request; specify the required monograph at quote stage so the documentation references it.

How to order

Ordering Sterile Water from Medabol

Kit and minimum
Sterile Water is sold by the kit (10 vials for 3 mL, 5 mL, 10 mL; 25 vials for 30 mL). The minimum is 1 kit per SKU, so an individual buyer can order a single kit and a lab can order many.
Price
Reference prices are listed per kit above, from $18.40. The kits of your whole quote list count together — 5–19 kits are 20% off every kit, and from 20 kits our sales team quotes the price — so Sterile Water adds up with anything else you order; your written quote has the final price.
Documents
COA per lot: the certificate of the lot you receive ships with the order; our sales team sends it before you order if you ask.
Shipping
Orders ship from China by international express courier. Shipping from $80 per order; the written quote confirms the exact charge for your destination.
Payment
Nothing is paid on this website. After you send your quote list, a sales representative confirms the amount and shipping on WhatsApp or by email and tells you in that chat how to pay.
Research goal
Listed under Lab essentials — Bacteriostatic water, sterile water, acetic acid water and benzyl alcohol.
