  The instrument is controlled on-line in real time from an external dedicated PC. In each of the elements of the A15 analyser, BioSystems has used leading edge tech nology to obtain optimum ana- lytical performance, as well as taking into account eco no my, robustness, easy use and maintenance. A three-axis Cartesian operating arm prepares the reactions.

• Page 9: Operating Arm

  The A15 analyser has a tray with 4 free positions for racks of reag e nts or samples. Each reagents rack can carry up to 10 reagents in 20 ml or 50 ml bottles. Each samples rack can contain up to 24 tubes of samples. The samples can be patients, calibrators or controls.

• Page 10: Reactions Rotor And Reading

  Service manual 1.1.3. Reactions rotor and reading The preparations are dispensed in an optical quality methacrylate reactions rotor thermos tated at 37ºC. The optical absorbance readings are taken directly on this rotor. Each reaction can be read for 10 minutes. The readings are taken as they are programmed in each measurement procedure.

  1.2. FUNCTIONING OF THE ANALYSER The A15 analyser is an automatic random access analyser specially designed for performing biochemical and turbi- dimetric clinical analyses. The analyser performs patient-by-patient analyses and enables the continual introduction of samples. The analyser is controlled from a dedicated PC that is permanently com muni cated to the instrument.
