— Common Questions
Got questions.
How is each batch of Bacteriostatic Water tested?+
Every batch is tested by an independent laboratory for identity and HPLC purity before it is listed. Merit identifies batches by date: the current certificate for Bacteriostatic Water 10 mL is the July 2026 batch, 0.850% purity by HPLC, published at meritsciences.com/coa/COA-2026-1CR7RH. The QR code on each vial opens the same page. Open the July 2026 batch certificate →
Why does Merit ship lyophilized?+
Lyophilized (freeze-dried) material is stable in sealed storage: ≥24 months at -20°C. Peptides held in solution degrade far faster, so every compound ships as a dry powder in a sealed vial.
What does "independently assayed" actually mean?+
Every batch is tested by a laboratory independent of the facility that made it, and the certificate is published before the batch is listed. You read the same identity and purity figures we do, which is what separates Merit from a reseller catalog.
How fast does it ship?+
48 hours from order to dispatch, Monday through Thursday. UPS Ground, tracked + insured. From San Antonio, TX, most US addresses receive within 3-5 business days.
