Introduction
This chapter gives the description
of the main components
of the
instrument and describes the hydraulic system.
5.2
Main components
The main components of the washer are the control electronics, the plate
transport mechanism, the manifold transport, the dispensing and aspirating
pumps, the keyboard with the LCD display and the power supply unit.

Hydraulic system
5.3.1
Dispensing system
The dispensing system consists of the input selection valves, the
diaphragm pump, the damping tube, the pinch valve and the manifold. The
input selection valves are connecting the respective liquid reservoirs (wash
and rinse solution) to the internal dispense circuits. The valves are
controlled by the washer software to select the correct liquid. The
dispensing pump delivers the liquid to the manifold, the operating time of
the pump together with the operating time of the pinch valve are
controlling the programmed volume.
5.3.2
Aspirating system
The aspiration is performed by a liquid pump connected to the aspiration
needles of the manifold. Compared to the traditional vacuum pump
operation this method produces much less noise and does not require tight,
closed bottles. Any kind of container with sufficient volume can be used
for the waste. In addition the risk of infectious aerosols is much reduced.
