Disinfection
When you need to disinfect or decontaminate the instrument, use the policies and
procedures defined by your laboratory.
Molecular Devices recommends that you disinfect the fluidics system after the washer has
not been used for more than a day or when changing the manifold. If the instrument is used
regularly, disinfect it at least once each week.
Always turn the power switch off and disconnect the power cord from the main power
source before using liquids to clean the instrument.
Use an appropriate disinfectant solution.
Recommended cleaning solutions include a 70% ethanol solution, a 2% SDS (sodium-
dodecylsulphate) solution, or a 4% glutaraldehyde solution.
Do not use bleach solutions. A thorough rinse still leaves traces of bleach in the fluidics
system that can corrupt the reagents in wash procedures.
Wipe the outside surfaces and the microplate carrier using a cloth or sponge that has been
lightly dampened with the disinfectant solution.
To remove the disinfectant residue, wipe the outside surfaces and the microplate carrier
using a cloth or sponge that has been lightly dampened with a 50% alcohol solution, and
then wipe again using a cloth or sponge that has been lightly dampened with water.
After all metal surfaces are dry, wipe the surfaces using a cloth or sponge that has been
lightly dampened with paraffin oil.
Disinfect the fluidics system by repeatedly dispensing and aspirating the disinfectant
solution.
To leave some solution in the fluidics system, turn off the power to the instrument
during the final aspiration.
Do not leave disinfectant solution in the fluidics system for more than 30 minutes.
To flush disinfectant from the tubing, run a manual or automatic rinse cycle using 200 mL
or more of distilled water.
WARNING! BIOHAZARD.
Always wear gloves when operating the instrument
and during cleaning procedures that could involve contact with either hazardous
or biohazardous materials or fluids.
