Chapter 4: Preventive Maintenance
Overview
A Preventive Maintenance (PM) regimen for the ELx405™ includes rinsing and
soaking the fluid path and cleaning the washer’s various components.
The chart on the next page summarizes Bio-Tek’s recommended maintenance tasks,
and indicates approximately how often each task should be performed. Daily and
periodic routines and minimal guidelines for frequency are listed. Beyond that, it is
difficult for Bio-Tek to recommend a fixed frequency for each task to be performed.
The risk and performance factors of your assays should determine the frequency with
which to conduct these tasks.
Therefore, Bio-Tek recommends you develop a maintenance schedule for your washer
based on the characteristics of the fluids used and the washer’s activity level. Some
questions you should consider are:
•
Are the fluids you’re using prone to dry and harden quickly? If yes, the dispense
and aspirate tubes can clog quickly, and therefore they must be rinsed
frequently and cleaned regularly.
•
Is the washer in use continuously, or does it sit idle for several hours or days at a time?
If the washer will be sitting idle, the tubes should be soaked to keep them in a
“wetted” state. The rinsing procedure (or the
AUTOPRIME program) should be
performed if the washer is idle for more than 3 hours.
•
Is a solution containing surfactant used throughout the day? The wash solutions in
use will affect the rinsing frequency. If the solution does not contain surfactant,
consider rinsing (or running
AUTOPRIME ) at least once an hour.
Schedule
The following chart recommends preventive maintenance tasks, the frequency
with which each task should be performed, and the pre-defined onboard
Maintenance program that should be run (if applicable).
It is important to note that the risk and performance factors
associated with your assays may require that some or all of the
procedures be performed more frequently than presented in this
schedule.
