Reagent System Sampling System: 1000 μl syringe for reagent sampling and 100 μl syringe for sample collection. Removable volume μL 400-110 for R1 and removable volume μl 180 -0 for R2 and R3. Sample removal volume of μl 30-1 with 0.1 μl yield, Reagent needle is equipped with an initial heater. In order to prevent the contamination of the reagents and samples, the prescription needles are equipped with a surface sensor and the presence of the system allows for the detection of the volume in the reference bottles. Reagent and sample needles, in addition to the surface sensor, are also equipped with a collision sensor.
