Sample Injection Tube
This is the stainless steel tube that carries the cells from the sample tube to the flow cell.
The tube is covered with an outer sleeve that serves as part of a droplet containment
system. See Figure 3-3. The droplet containment system employs a vacuum pump to
aspirate fluid and prevent drips from splashing onto the countertop.

Tube Support Arm
This arm supports the sample tube. The arm has three positions: centered below the
sample tube, to the right, or to the left of the sample tube. Its main function is to
activate the droplet containment vacuum. The vacuum is activated when the arm is in
the right or left positions and off when the arm is centered.
