Overview
A
Preventive Maintenance (PM)
regimen for the 405 LS includes rinsing and
soaking the fluid path and cleaning and/or autoclaving the various components.
The level of maintenance required to keep the instrument performing as expected
is dependent on several factors, including the type of fluid dispensed, the
frequency of use, and the work habits employed.
The
Recommended Maintenance Schedule on page 119
summarizes BioTek’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 BioTek to recommend a fixed
frequency for each task to be performed. The frequency of conducting these tasks
must be based on the risk and performance factors of your assays.
Develop a maintenance schedule for your 405 LS based on the characteristics of the
fluids used and the activity level. Here are some guidelines for each component:
Washer
o
When using fluids prone to dry and harden quickly, the washer’s dispense and
aspirate tubes can clog quickly, and must be rinsed frequently and cleaned
regularly. Run
AutoClean ultrasonic cleaning regularly, when available.
Otherwise, Remove and clean the washer manifold on page 131.
o
If the washer will be idle for several hours or days at a time, soak the tubes to
keep them in a ”wetted” state. Enable
AutoPrime if the washer is idle for more
than 3 hours.
o
Wash solutions affect the rinse frequency. If the solution does not contain
surfactant, consider rinsing (or running AutoPrime ) at least once an hour.
Recommended Maintenance Schedule
The schedule recommends preventive maintenance tasks, the frequency with which
each task should be performed, and the predefined 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 suggested in this schedule.

Water : Daily maintenance is the key to keeping the liquid handler performing
to specifications. In the maintenance procedures provided in this manual, the
requirement to use distilled (dH2O) or deionized (DI) water can be met by
