Overnight Loop
To keep the wash manifolds in a wetted condition, you can run these predefined
protocols to soak the tubes for several hours at a time:
l OVERNIGHT_LOOP: requires the washer to remain turned on.
l RINSE_AND_SOAK: alternatively, run this protocol and turn off the
instrument after the soak begins. The tubes will soak in the priming trough
until the instrument is turned on again.

Recommended for optimum performance, AutoPrime keeps the tubing wet in
between runs and can be an essential part of your daily maintenance routine.
About AutoPrime
AutoPrime automatically primes the tubing whenever the instrument is idle for a
specified time. Keeping the tubes wet prevents clogging and mitigates fluid
evaporation at the tips. AutoPrime's submerge feature lets you soak the tubes for
extended periods, which is an effective maintenance option.
