Liquid Testing the 405™ Microplate Washer LS

Which Tests to Perform?

We recommend that you perform these routine tests before first use (after the
IQ) and then monthly:
Washer
Dispense Precision Test.
l
from tube to tube across the manifold.
Evacuation Efficiency Test.
l
aspiration aspect of plate washing. The lower the residuals per well, the better the
evacuation efficiency of the washer.
Specially equipped washers: with Buffer Switching and/or Verify™ Technology,
perform test annually (starting one year after installation):
Annual Buffer Switching Test.
l
tube to tube across the manifold, for each valve, when the washer is equipped with
buffer switching.
Verify Sensor Test.
l
against a microplate absorbance reader's determination to ensure accurate, repeatable
volume-level detection.
Perform the tests applicable to the installed manifold type and feature set:
If you have:
96-Tube Manifold
192-Tube Manifold
Buffer Switching
Vacuum Filtration Module
