Cedex Bio System 12 ISE description
Hardware
ISE tower A hollow, transparent cylinder with multiple inlets and outlets for air and solutions.
In the ISE tower, samples and diluents are mixed using an air stream.
Tubing Tubing is used for transporting the fluids. It connects the ISE unit with the water and
waste system, and also with the ISE Reference Solution and ISE Calibrator
indirect/urine bottles, which are placed on the ISE unit.
Sensors The ISE sample sensor detects the presence of liquid (sample, control, standard
solution, or ISE Calibrator indirect/urine) or air and enables the correct placing of
segments for measurement and cleaning.
The ISE Reference Solution sensor detects the presence of ISE Reference Solution.
ISE fluid bottles Two bottles are placed on the ISE unit:
o ISE Calibrator indirect/urine bottle (blue label)
o ISE Reference Solution bottle (red label)
Level monitoring is performed on the basis of weight, the bottles are placed on scales.
