4 Functional characteristics
4.1
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 no air
bubbles are leaving the cannula. Perform regular and
smooth movements and make sure that the outer housing
(2) is always pushed all the way down.
4.2 Volume adjustment
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
and
250 ml
: turn
adjustment screw counterclockwise until the arrow is easy to move, choose
your desired volume and then fix the adjustment screw.)
4.3 Dispensing
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.
Raise the outer housing (2) until it stops at the point set by the volume rocker
switch. The 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.
