ENTRIFUGE WELL
The MCS+ centrifuge well is designed with the following components.
Optical bowl sensor
There is an optical sensor located on the upper portion of the centrifuge well. The
sensor is aimed at the core of the bowl and will measure optical reflection as the
various blood components pass in front of the optical beam.
Note: The interface between the optical sensor in the centrifuge well and the con-
tents of the bowl is often referred to as “bowl optics” and will be discussed in fur-
ther detail in each respective MCS+ protocol manual.

Caution: The optical bowl sensor must be kept clean, and should be cleared after
any spills. A dirty or clouded lens will interfere with proper functioning of the
MCS+ device.
Fluid detector(s)
The MCS+ centrifuge well is equipped with an electronic fluid detection system
designed to detect the presence of liquid. Depending on the style of centrifuge in
use, there will be either one long fluid detector, or one or two round fluid
detector(s) mounted on the wall of the centrifuge well. The MCS+ safety system
will automatically stop the centrifuge (and the pumps) if there is contact between
liquid of any sort and the fluid detector(s).
