LEAN THE AS
If using a FlowPrep, gas delivery tubes should be wiped with a clean, lint-free cloth after each use
to remove any particles of sample that may have adhered to the tube. If a gas delivery tube
becomes clogged or damaged, it should be replaced.
1. Remove the gas delivery tube from the flexible tubing.
2. Attach a new gas delivery tube by pressing the flexible tubing over the gas delivery tube.
Ensure that the flexible tubing completely covers the ferrule at the end of the gas delivery
tube.

UBRICATE THE LEVATOR
The elevator screw is lubricated before it leaves the factory and should not require lubricating. If
the elevator starts to vibrate or becomes noisy when traveling, contact a Micromeritics Service
Representative for disposition.
Should lubrication become necessary, apply a light coat of Teflon Magnalube-G grease
[Micromeritics part number 004-16163-00] to the elevator screw. Do not grease the guide rods.
