8 - CLEANING AND STERILISATION

Cleaning:
External surfaces of the pipetting pushbutton (1)
- Fig. 6, the ejector pushbutton (2), the handgrip
(5) and the body (6) can be cleaned with tissue
dipped in isopropyl alcohol. Remaining parts
removed from the pipette during disassembly (7
to 17) can be washed with distilled water or iso-
propyl alcohol.
Sterilisation:
The pipette can be subjected to sterilisation, as
a whole, in the autoclave at temperature 121°C
for 20 minutes. After performing the sterilisation
the pipette should be dried and cooled down to
room temperature.
It is recommended:
- to sterilise the pipettes in an autoclave with
initial vacuum and drying cycle,
- to test pipette calibration every 10 sterilisation
cycles.
The pipettes are UV resistant which was con-
firmed by our tests. The recommended distance
from the radiation source to exposed element
should be not less than 50 cm. Prolonged and
very intense UV exposure can cause de-col-
oration of pipette parts, without affecting its per-
formance.
