Preparing the sheath container

Introduction

This topic describes how to prepare the sheath container.

Note:

If your system is using the FFSS, see the documentation

provided with your system.

When to check the
sheath container

Check the fluid levels in the sheath container every time you use
the cytometer. This ensures that you do not run out of sheath fluid
during an experiment.
