Dispensing steps

4. Dispense liquid. You can change some parameters during dispensing.

5. There are two possible variants for continuing execution:

• Renewed aspiration

Perform further dispensing process with the previously set parameters.

• Empty the Combitip completely

Dispense the residual liquid from the Combitip to finish dispensing and to release

the Combitip.

5.2 Prepare the Multipette stream/Repeater stream

This chapter describes general operating instructions for Multipette stream/Repeater

stream. The Multipette stream/Repeater stream and Multipette Xstream/

Repeater Xstream differ as regards the available operating modes (see p. 11). Setting the

parameters is identical for every operating mode.

Proceed as follows to set the operating mode and the parameters:

1. Select a suitable Combitip and insert.

The size of the Combitip is recognized automatically by the Multipette stream/Repeater

stream and shown on the display for approx. 1 second.

2. If the Multipette stream/Repeater stream is in sleep mode, press any key to activate it.

3. Set the desired operating mode using the selection dial. The selected mode is shown

temporarily in the display.

The start display shows the parameters of the last operation with a Combitip of the

same size.

4. Setting the parameters . It is also possible to change some parameters in all operating

modes during operation. For this, press the select rocker switch during operation and

set the parameters.

• Change between the parameters using the select rocker switch.

• Change the parameters using the +/- rocker switch.

5. Press the actuate key to save your settings.

The display shows:

The liquid dispensing angle should always be as steep as possible. A dispensing

angle greater than 45° can result in an incorrect dispensing volume during the

final dispensing steps.

At high viscosity, select low aspiration and dispensing speeds. Solutions with a

viscosity up to 300 mPa·s must be dispensed using a Combitip with a maximum

size of 25 mL, set at the lowest speed. If a 50 mL Combitip is used, the viscosity

must not exceed 100 mPa·s.
