Questions

Good to know.

What is reconstitution solution?
A sterile mixing solution used to reconstitute lyophilized (freeze-dried) materials in research and laboratory settings — commonly known as bacteriostatic water. It contains a small amount of benzyl alcohol so a vial can be accessed multiple times. It is not the same as sterile water or saline — see bacteriostatic water vs sterile water and bacteriostatic water vs saline.
How should I store it?
Room temperature, away from direct light. Each batch's shelf life is printed on the vial. Our bacteriostatic water shelf life and storage guide covers opened vials and temperature in detail.
How fast do orders ship?
Orders before 2pm ET ship the same business day from Costa Mesa, California with tracked delivery. Most domestic orders arrive in 2–4 days. See our shipping and returns policy.
Can I get a Certificate of Analysis?
Yes — a COA is available for every batch on request (how to request one), and automatically for wholesale accounts. New to COAs? Read how to read a Certificate of Analysis.
