Testing process

How a lot gets released

Four steps, in order, for the lot currently on the shelf.

  1. Filled and sealed as one lot

    A single production run is filled into 30 mL rubber-stopper vials and sealed. Every vial from that run carries the same lot code on its label.

    Group of sealed 30 mL bacteriostatic water vials with pink flip-off caps from a single production lot

  2. Sampled and sent out for analysis

    A sample from the finished lot goes to Chromate, an independent laboratory. Nothing from the run is released until the lab reports back.

  3. Analysed against a written specification

    Identity and benzyl alcohol concentration by RP-HPLC with UV detection. Sterility by USP <1223> BacT/ALERT. Endotoxins by kinetic chromogenic LAL assay.

Sterile fill & lot control

What holds the standard between lots

  • Sterility verified per lot

    Sterility is confirmed on every production lot by USP <1223> BacT/ALERT before that lot is released for sale.

  • Sealed multi-dose closure

    A sealed rubber-stopper vial preserved with 0.9% benzyl alcohol, built for repeated access under proper aseptic technique.

  • One lot, one certificate

    The lot code printed on your vial label matches the certificate published on this page. Nothing ships without one.
