28.7.4 Liquid Handling (LQH)
28.7.4.1 Liquid Handling parameters
The parameters for the Liquid Handling function are defined under
[Liq-
uid Handling param.].
Function
Type of Liquid Handling function.
Selection Dose | Fill | Aspirate | Eject | Exchange posi-
tion | Change port | Compensate | End volume
Dose
The given volume is dosed. The dosing cylinder neither is automatically
filled before nor afterwards.
Fill
The dosing cylinder is filled. The valve disc then remains at the selected
port.
Aspirate
Liquid is aspirated. The dosing cylinder neither is automatically filled
before nor afterwards. The aspirating volume has to be aspirated with
a single piston stroke.
Eject
The whole cylinder content is ejected. The piston is, in contrast to the
function End volume, lowered to the stop point, i.e. past the maxi-
mum volume mark. This function should only be carried out for prepar-
ing a dosing unit before the pipetting procedure.
Exchange position
The dosing cylinder is filled. This means that, for example, air can be
aspirated via Port 4. The valve disc is then rotated to Port 2 and the
dosing drive can be removed from the dosing unit.
Change port
The stopcock is moved to the given port, but no piston movement
takes place.
