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
l Dispense Precision Test. Precision tests measure the variability of volumes dispensed
from tube to tube across the manifold.
l Evacuation Efficiency Test. Measures the residual volume per well after the
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):
l Annual Buffer Switching Test. Measures the variability of volumes dispensed from
tube to tube across the manifold, for each valve, when the washer is equipped with
buffer switching.
l Verify Sensor Test. Compares the ultrasonic level sensor's measurement precision
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:
