Laboratory supplies & diluents

About this category

Bacteriostatic water is supplied as 10 ml × 10 vials of sterile liquid containing 0.9% benzyl alcohol — a liquid, never a powder. Acetic acid is supplied as 3 ml × 10 vials of sterile liquid, used where a sequence needs a mildly acidic vehicle to go fully into solution.

Both are sold as multi-vial liquid kits and ship with the rest of your order in the same tracked consignment.

Benzyl alcohol, septa and the small details that matter

Bacteriostatic water is a sterile liquid containing 0.9% benzyl alcohol as a preservative — a detail that surprises buyers expecting a powder, and one that changes how vials are handled: the septum is pierced once per draw with a sterile needle, and multi-use vials are held refrigerated between draws for the window the reference practice describes.

Acetic acid, supplied as 3 ml × 10 sterile liquid vials, is the alternative vehicle for sequences that dissolve poorly at neutral pH. Which vehicle a protocol needs is a decision from the reference method, not from preference — the calculator handles the volume arithmetic either way.

Ordering diluent with your kits

Both diluents travel in the same tracked consignment as peptide kits, so a reconstitution plan never waits on a separate shipment. Because diluent volumes per vial depend on the target concentration, the reconstitution calculator converts concentration into millilitres per vial before an order is placed.

If a protocol needs both vehicles, the quantities are small enough that a single supplies kit of each covers most published method conventions — 10 ml × 10 vials of bacteriostatic water and 3 ml × 10 vials of acetic acid per kit.
