Figure 1-17 Reaction tank
The reaction tank contains non reactive oil, which keeps the temperature of the liquid in
reaction tray (RRV) cuvettes at a constant 37 °C ±0.1 °C. The temperature is controlled
by a heater and a thermostat.
Sample tray
Sample tray
The sample tray holds patient samples, controls, calibrators, and diluents for
measurement. The tray rotates to move the samples to the aspiration position.
The sample tray has two sections:
STT (outer section): Used for general samples and reference samples for multipoint
calibrations. It has two rows, each with 42 positions (total 84). You can place serum or
urine samples into each position.
A barcode reader identifies samples in the STT. It can interpret barcode formats Code 39,
Interleaved 2 of 5, Codabar, and Code 128 format A, B and special characters ( . - + / * $
% ).
CTT (inner section): Used for calibrators, controls, and special purpose diluents. It has
two rows. The outer row has 34 positions and the inner row has 27 positions (total 61).
The CTT is water-cooled.
