Sartorius BIOHIT Biofiller Operator Instructions

Biofiller
Operator Instructions
Introduction
Biofiller may be used with glass or plastic pipettes to facilitate the pipetting
of a wide range of liquids. Pipettes within the volume range of 1ml to 100ml
can be used.
When correctly used, liquid only comes into contact with the pipette.
Operating Instructions
1. Fitting the pipette
Carefully attach the pipette by inserting it into the silicone holder inside
the nose cone. Do not use force.
2. Filling the pipette
Press the suction bulb first whilst holding the Biofiller 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 level is slightly above the required
mark.
NOTE:
Do not allow liquid to enter the Biofiller. The function of the filter
will be severely impaired reducing suction efficiency.
Spare filters are available see over.
3. Meniscus Adjustment
Wipe the pipette tip with a suitable lint-free tissue. Press the dispense
lever down slowly until the required meniscus has been reached.
4. Dispensing
Hold the receiving vessel in an inclined position, placing the pipette tip
against the receiving vessel's wall. Press the dispense lever down to empty
the pipette.
5. 'Blow-out' Pipettes
As soon as the meniscus in the pipette comes to a standstill, press the
discharge button to expel the last few drops. To ensure a complete
dispense Procedure, wipe the pipette tip upwards a few millimeters along
the inside wall of the receiving vessel.
