The tubing is attached to the flowcell using threaded inserts; push the sample
tubes into the inserts and screw into the top of the flowcell.
The tubing is then inserted into the pinch valve channel; push
both
tubes
down into the pinch valve on the side of the cell area. Ensure the join between
the PTFE and silicone tubing is within the cell area.
Cleaning cuvettes
Two main types of cuvette are available:
Disposable polystyrene
Do not clean and re-use disposable cuvettes. It gives inaccurate results.
Reusable glass or quartz
The cleaning procedure depends on the sample measured so specific instructions
cannot be given. Follow these guidelines:
Rinse the cuvette with the dispersant that was used for the measurement.
Try submerging the cuvette in an ultrasonic bath of clean solvent.
Once clean, wipe the cuvette with a lint free tissue (photographers’ lens clean-
ing tissues are recommended).
The smaller and more dilute the sample, the more important cleanliness is.
