Product description
EASY 9
may be used with glass or plastic pipettes to facilitate the pipetting of a wide range of liquids. Pipettes within
the volume range of 0.1 ml to 100 ml can be used. If the instrument is correctly used, the liquid comes into contact
with the pipette only.

Pipetting
1.
Fit the pipette
Carefully attach the pipette by inserting it into the silicone adapter inside the nose cone. Do not use force.
2.
Fill the pipette
Press the suction bellows first whilst holding the
EASY 9
in a vertical position with the pipette tip down. Place the
tip of the pipette into the liquid to be aspirated. Press the aspirate lever slowly upwards allowing the liquid to fill the
pipette so that the meniscus is slightly above the required mark.
Note:
Do not allow liquid enter the
EASY 9
. The function of the filter will be severely impaired reducing suction efficiency.
Spare filters are available see over.
The further up the lever is pressed, the stronger the suction becomes and the quicker the meniscus rises.
In the case of large pipettes the vacuum contained in the suction bellows is not sufficient to draw in all the liquid at
once. Therefore, press the suction bellows again and continue drawing up liquid.
3.
Adjust the meniscus
Wipe the pipette tip with a suitable lint-free tissue. Press the dispense lever down slowly until the required
meniscus has been reached.
4.
Dispense the pipette
Hold the collecting vessel in an inclined position, placing the pipette tip against the collecting vessel’s wall. Press
the dispense lever down to empty the pipette.
5.
In the case of ‘blow-out’ pipettes
As soon as the meniscus in the pipette comes to a standstill, press the blow-out bellows to expel the last few
drops. To ensure a complete dispense procedure, wipe the pipette tip upwards a few millimetres along the inside
wall of the collecting vessel.
6.
‘To deliver’ pipettes
As soon as the liquid in the pipette comes to a standstill, wait for the period of time required to ensure the timed
liquid has been fully dispensed.
7.
Remove pipette
Hold the pipette at its upper end and gently twist and remove from the silicone adapter.
8.
Replace the filter and clean the adapter
If the pipette has been overfilled or the suction capacity is impaired, proceed as described below:
a) Remove the pipette
b) Unscrew the nose cone
c)
Remove the silicone adapter out of the housing by pulling it upwards. Use a wash bottle to accurately rinse the
adapter. Blow out the liquid and allow drying completely.
d) Remove the filter and replace with a new one.
e) Re-assemble
9.
Leak test
Attach a pipette and aspirate liquid to minimum of half the capacity of the pipette. Hold the pipette over a suitable
reservoir. If liquid drips from the pipette tip, dismantle the unit (see 8) and re-assemble correctly.
10. Return for repair
When returning
EASY 9
for repair, please ensure the instrument has been cleaned and decontaminated. Please
ask for a decontamination statement form.
