3 Functional characteristics
3.1 Air-purging
Before starting to pump, it is essential to place a collecting
vessel under the cannula. The valve axle has to be in the
dispensing position (arrow up).
Now perform short pumping movements until there are no
more air bubbles. Perform constant and smooth movements
and make sure that the outer housing (2) is always pushed all
the way down.
3.2 Volume adjustment
The quick-volume-adjustment is performed with the adusting switch. This assu-
res a maximum of exact reproduction of liquid quantities. To set the required
dispensing quantity, turn the calibration screw counter clockwise until the adjus-
ting switch can be moved easily. Tighten the calibration screw clockwise after the
indicator has been set to the required value.
3.3 Dispensing
Avoid personal injury from chemicals. To protect yourself wear eye protection and
use appropriate safety equipment and clothing.
Please follow all safety instructions and observe operating procedures.
Raise the plunger until it stops at the point set by the adjusting switch. By pres-
sing down the plunger to the lowest point the set quantity will be dispensed into
the collecting vessel. The plunger movements should be smooth and constant to
achieve an exact ejection volume.
3.4 Dispensing lock
The ejection cannula of the "Labmax airless" can be drained sa-
fely and easily. Turn the valve axle 180° to the left until it stops
(arrow downward). This way it is possible to lock the dispenser
which prevents any further drop out. The closing caps are no
longer needed. If slightly tilted backwards the ejection cannula
drains into the bottle.
