Getting Started
Priming
Open the cap of the dispensing tube (Fig. 6). For safety hold the discharge
tube orifice on the inner wall of a suitable receiving vessel.
1. Set the valve to 'Recirculate'. (Fig. 7)
For priming gently pull up the piston approx, 30mm and push it down
rapidly until the lower stop. Repeat this procedure 5 times
(Fig. 8).
2. Turn valve to 'Dispense' (Fig.9).
To avoid splashes when priming hold the discharge tube on the inner
wall of a suitable receiving vessel and dispense liquid to prime the
discharge tube until it is bubble free, Wipe away any remaining drops from
the discharge tube.
Note :
Before using the instrument for the first time, ensure it is rinsed carefully and
discard the first few samples dispensed.
Avoid splashing.
Important Guidelines
Operating limitations
This instrument is designed for dispensing liquids, observing the following physical limits:
● Use temperature from +15°C to +40°C (from 59°F to 104°F) of instrument and reagent
● Vapor pressure up to max. 600 mbar. Aspirate slowly above 300 mbar, in order to
prevent the liquid from boiling.
● Kinematic viscosity 500 mm
(dynamic viscosity [mPas] = kinematic viscosity [mm
● Density: up to 2.2 g/cm
