The quick-volume-adjustment is performed with the volume rocker switch (3).
To set the required dispensing quantity, hold the rocker switch pressed and move the arrow
to the desired volume. Now unhand the rocker and make sure it fits correctly into the
sprockets. (For Labmax 100 ml
the arrow is easy to move, choose your desired volume and then fix the adjustment screw.)

Avoid personal injury from chemicals. To protect your self wear eye protection and use
appropriate safety equipment and clothing.
Please follow all safety instructions and observe operating procedures.

set quantity will be dispensed into the collecting vessel by pressing down the outer housing
(2) to the lowest point. The movements should be smooth and constant to achieve an exact
ejection volume.
