When you change your BactoBox® setup.
Example: You replace the flow cell.
Example: You replace the external filter.
Example: You replace the tubing kit.
When you switch from the SBT dilution vial to the DIY dilution vial.
Once the liquid passes through BactoBox®, its properties may change. Trace residues of disinfection liquid from the previous cleaning cycle can lower both the conductivity and the concentration of microspheres.
Always discard the QC vial after use!
What is a vial?
In SBT terms, a vial is a 15 mL conical centrifuge tube.
BactoBox® connects to a vial via the tubing kit. See the vial rack for a convenient way to store vials.
