Cleaning Instructions - BRAND Transferpette S-8 Mode D'emploi

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. We recommend using the BRAND
leak testing instrument PLT unit.
Alternatively: to do this aspirate a sample, and then hold the instru-
ment in a vertical position for about 10 sec. If a drop forms at the tip
orifices, see the troubleshooting guide, page 50.

Cleaning instructions

1.
Clean single nose cones, pistons and nose cone support bar/piston
support bar (these components only) with soap solution or isopro-
pyl alcohol. Afterwards, rinse 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!
