Phase B: Dilution vial fails

Before you move on

You are here because qualification phase B (dilution vial) failed. E.g., the measurement gave an error, or the concentration was outside the allowed range.

This assumes that phase A (QC vial) passed!

Is this not the case? Then let's take a step back. Is it phase A (QC test on the QC vial) that failed?

Use the SBT-provided dilution vial

Often, the issues are due to in-house or third-party consumables. E.g., do-it-yourself diluent and third-party empty vials.

Measure again with an SBT-provided dilution vial.

SBT's dilution vial is ready to use

We did everything for you already. SBT has a rigorous quality control procedure to ensure that the dilution vial pairs perfectly with BactoBox®.

The dilution vial is for single use only

Discard the dilution vial after use. Once it's been through BactoBox®, we can no longer guarantee the sterility and purity.
