SMOOTHIE
Operator Instructions
Introduction
The Smoothie pipette filler may be used with glass or plastic pipettes
to facilitate the pipetting of a wide range of liquids. Pipettes within the
volume range of 1 ml to 25 ml can be used. When correctly used, the
liquid should only come 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. Choosing the correct thumb wheel setting
The Smoothie is equipped with a rotating thumb wheel which advances
the piston up and down the barrel for aspiration and dispensing. The
unique thumb wheel can be set at two different dispense resolutions for
maximum accuracy depending on the volume of liquid being dispensed.
Fast filling for volumes of 10 ml to 25 ml is possible when the thumb
wheel is positioned to the right. This is the default setting. Whenever
you are working with pipettes smaller than 10 ml we recommend that
you choose the fine setting – whereby the thumb wheel is positioned to
the left.
To change the thumb wheel setting the piston must be in its lowest
position (image 1A). To change from the default setting to the fine
setting use the thumb of your right hand to push the thumb wheel
by pressing the thumb wheel button all the way in to the left (image
1B). With your left hand rotate the fixing button until the gear locator
is locked in its respective groove ( image 1C), thus holding the thumb
wheel in its new position. The thumb wheel should now be positioned
to the left. The pipette is now ready for work in its fine setting as
recommended for volumes less than10 ml.
