2.2.5. Main Dilutor
This unit includes two dilutor channels – one (pair) for diluent, and another one for lyse, and one
for lyse EOS reagents. There are two stepper motors, a common motor opto board, four
syringes with piston rods and gear transmission.
Maintenance should be provided to the piston tips, by applying neutral silicon grease
to the cogged end of the Dilutor and Lyse pistons, between the syringe and the tip
itself. This will ensure optimum sealing and longer lifetime of piston tips.
DO NOT grease the piston with black bottom plastic part!
Greasing of the cogged transmission parts (cogwheel and cogged bar) should be
done regularly using machine grease.
It is recommended to check and repeat greasing of piston tips, and transmission gear
every year, or after 10000 measurements.
