PLC5 Leaf Cuvette
The cuvette leaf gaskets will require periodic replacement. Over time the gaskets can become worn,
damaged, cracked and/or creased. The leaf gaskets are seated in individual channels with adhesive
backing. We strongly recommend that the cuvette head is in the open position when not in use to keep
the gaskets from compressing.
Replacement of leaf gaskets
1. Loosen the “Cuvette Head Release Screw” by rotating it counter-clockwise and slide it out from the
handle.
2. The cuvette head can now drop down making it very easy to replace the leaf gaskets.
3. Using a fine screwdriver gently pry the old leaf gaskets out of each respective channel. There are
two rectangular gaskets below the chamber window (25 x 18mm) and two round gaskets (18mm
diameter) at the rear of the chamber. Make sure each channel is clean of any debris and adhesive
material that may have accumulated in that area.
4. Carefully replace the gaskets and make sure that they are seated properly in each respective
channel.
5. Close the cuvette head and reassemble by securing everything in place using the “Cuvette Head
Release Screw”. Slide the screw into the small hole and turn clockwise until snug. Do not
overtighten.
