PIPETMAN® L
Lock System
For additional safety, the volume selected is lockable.
1.
Unlock the thumbwheel
by pushing it up with
your thumb.
2.
Set the volume
by turning the
thumbwheel.
The thumbwheel can be
turned using one hand
to slowly reach the
required setting.
3.
Lock the newly set
volume by pushing
down on the
thumbwheel.
To obtain maximum accuracy when setting the volume:
●
When
decreasing
the volume setting, slowly reach the
required setting, making sure not to overshoot the mark.
●
When
increasing
the volume setting, pass the required
value by 1/3 of a turn and then slowly decrease to reach
the volume, making sure not to overshoot the mark.
User Adjustments (Fixed Volume Models Only)
PIPETMAN L fixed volume models are factory calibrated using
distilled water and very high precision balances. The nominal
volume may be adjusted slightly to compensate for liquids of
different density or viscosity.
To accommodate for density or viscosity, an adjustment of one
full turn of the adjustment key in either direction equals:
± 0.05 μL (F1L to F2L)
± 0.2 μL (F5L to F10L)
± 0.5 μL (F20L to F25L)
± 2.0 μL (F50L to F100L)
± 5.1 μL (F200L to F250L)
± 20 μL (F300L to F1000L)
± 102 μL (F5000L)
The cover is graduated in
tenths of the key revolution
(letters A, B,..., J) and is read
from left to right. Each small
graduation mark represents
0.25 of the distance between each letter.
To adjust the nominal volume setting
to compensate for a specific density or
viscosity, engage the two hooks of the
spanner tool inside the two small holes on
the top of the body, and then turn the key
slowly:
●
Clockwise
to decrease the volume;
making sure not to overshoot the
mark.
●
Counterclockwise
to increase the
volume; pass the required value by
1/4 turn, and then slowly decrease
the volume to reach the required
setting.
