5.2 Mounting Laboratory Test Cuvette to Sensor
LTC is mounted on the PR-23-AC sensor using a 2.5” EPDM sanitary gasket and clamp
(Figure 5.2). Position the gasket in its seating groove with the lip downward. Now position
the assembled LTC with the gasket groove correctly seated on to the gasket. Attach
clamp and lock. Check that the clamp is tight, if it is not adjust the tension using the clamp
adjustment screw.

5.3 Connecting hoses
The temperature control Water Jacket is connected to the Thermostatic bath and to an
external sample delivery system using the 8 mm (0.3 inch) hoses (Figure 5.3). The hoses
to the Thermostatic bath should each have a ball valve inserted between the thermostatic
bath and the water jacket. The valves are to enable the shutting off of the water flow to
the water jacket to allow disassembly for cleaning. The water jacket inlet pipe is the one
positioned nearest the base and the outlet is positioned at the top. Thus the circulation
through the water jacket is from bottom to top, therefore avoiding air pocket formation within
the water jacket.
The continuous sample supply hoses allow liquid flow throught the cuvette via two pipes
at the top. The hoses are connected for the inlet and outlet hose connections and to an
external sample delivery system with a pump. With the sample delivery pump the sample
can be further directed to an external laboratory pilot process, e.g. kilolab filtration.
