Bacteriostatic water with 0.9% benzyl alcohol, for laboratory research use. Made in the USA and third-party tested.

Single 10ml vial of bacteriostatic water with 0.9% benzyl alcohol.

Single 30ml vial of bacteriostatic water with 0.9% benzyl alcohol. Larger format for higher-volume reconstitution.
Shaking creates shear at the air liquid interface and foams the solution. Both denature peptides invisibly, so the vial looks perfect and no longer works.
Lyophilization freeze dries a peptide into a stable solid by removing the water it needs to degrade. Reconstitution reverses that, and starts the clock again.
Refrigerate at 2 to 8 C, protect from light, avoid freeze thaw cycling, and discard at 28 days from first puncture. Storage is where most sample loss happens.
