UVETTE ROTOR AND WASH POSITIONS The filling of the cuvette rotor is done bv means of a bellows pump that is driven bv a stepper motor The volume is 4 x 500 ul per rotation cvcle In total 4 cuvettes are washed filled and emptied at the same time Also the sample needle is washed with 500 ul water at the wash position When the water pump is switched on water will be pumped from the water bottle to the water cask The water cask is equipped with a svstem for detecting the water level see section 2 4 3 When the water level is too low the water pump will be switched on and when the level is high enough the pump will be switched off When the switch off circuit is defective the water will flow back into the water container via the overflow connection The filling of the cuvette rotor and sample wash position is performed as follows Valve V6 to V10 are not activated the bellows goes downwards and is aspirating water Then V6 to V10 are activated and the bellows goes upwards and is dispensing water in the cuvette rotor and sample wash position and the valves V6 to V10 are de activated again The reagent svringe fills the reagent wash position The reagent valve will move to the aspirate position and the syringe plunger will go downwards and the syringe will be filled with water Then the valve will move to the dispense position and the plunger will go upwards and water will be dispensed into the reagent wash position 2 6 2 EMPTYING THE
