Servicing and Cleaning
Servicing
In order to assure proper functioning, the Transferpette
should be serviced and cleaned at regular intervals.
What is to be inspected?
1.
Inspect nose cones, pistons and seals for damage and contamination.
2.
Test the sealing of the instrument. To do this aspirate a sample, and
then hold the instrument in a vertical position for about 10 sec. If a
drop forms at the tip orifices, see the troubleshooting guide, page 44.
Cleaning instructions
1.
Clean single nose cones, pistons and nose cone
support bar/piston support bar (these compo-
nents only) with soap solution or isopropyl alco-
hol. Afterwards, rince with distilled water.
2.
Let these parts dry and cool down completely.
Residual moisture in the nose cones may result in
a loss of accuracy.
3.
Lubricate the piston with a very thin coating of the
silicone oil supplied. For the central guide rod (Z)
only use the recommended fluorstatic grease!
Disconnecting handle from manifold
1.
Eject the pipette tips.
2.
To disconnect the manifold, pull it downward
as far as possible, and only then turn it
clockwise.
After one rotation, it should no longer be
pulled downward while it is being turned.
Attention:
Improper handling can damage the unit!
