Enter the dispensing speed of the liquid in the
Dispense speed
field. Input range: 0.2
mm/s – 110
mm/s.
Select a low dispensing speed if you dispense larger volumes in empty vessels. A lower dispensing
speed decreases the risk of liquid spraying back. Use larger vessels to achieve better mixing results due
to a higher speed.
Enter the blow-out delay in the
Blow delay
field. Input range: 0
ms – 99999
ms.
The delay is the break between the end of the dispensing during liquid dispensing and blow-out. This
setting has an effect on the
Transfer type
Pipette
.
If you use liquids with high wetting behavior (e.g., solutions which contain proteins or detergents,
organic solvents) and delayed drain-off characteristics (highly viscous liquids), delay the blow-out. The
residual liquid collects in the lower part of the tip prior to the blow-out.
If you use liquids with low wetting behavior (e.g., water, saline solutions), set the blow-out delay to
0
.
Enter the dispensing speed of the blow-out in the
Blow speed
field. Application.: 0.2
mm/s – 110
mm/s.
Using liquids that tend to form bubbles on the outlet of the pipette tip increases the dispensing speed of
the blow-out. Decrease the dispensing speed if liquid sprays back into the vessel. This setting has an
effect on the
Transfer type
Pipette
.
In the
Blow movement
field, enter the path of the piston during blow-out. Input range: 0
% – 100
%
as
percentaged value of the setting
Initial stroke
.
No blow-out will be carried out during when
0
is entered. The full piston path is part of the dispensing
step.
When entering
100
, the entire piston path is available for the blow-out. The blow-out will be conducted
using the
Blow delay
and
Blow speed
parameters.
Increase and decrease the
Blow movement
along with the
Blow speed
setting. This setting only has an
effect on the
Transfer type
Pipette
.
In the
Initial stroke
field, enter the path the piston takes before the liquid aspiration. Input range: 0
%
–
100
% of the available path, dependent on the type of dispensing tool.
The higher the value, the larger the amount of piston path that is available for the blow-out after liquid
dispensing. To decrease the amount of residual liquid in the pipette tip after dispensing, increase the
value. To decrease the formation of foam during dispensing, decrease the value. Reducing the value can
increase the risk of dispensing errors. A blow-out cannot be conducted if
0
is entered.
If you change the value, the pipette tips will be automatically changed before the liquid aspiration due to
technical reasons.
In the
Prewetting
field, enter the number of piston movements for pre-wetting the pipette tips. Input
range: 0 – 9 cycles
Non-wetted pipette tips can be pre-wetted to create the same conditions for dispensings.
Wetting the pipette tips:
•
For liquids with low vapor pressure.
•
For liquids with reduced surface tension and delayed drain-off characteristics.
