2.2.4. Main Dilutor
There are two stepper motors, a common motor opto board, four syringes and piston rods
with gear transmission.
Maintenance should be provided to the piston tips, by applying neutral silicon
grease to the cogged end of the Macro and Lyse pistons, between the syringe and
the tip itself. This will ensure optimum sealing and longer lifetime of piston tips.
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.
