10. Maintenance
Biohit
m
LINE pipettors have been designed for easy in-house service.
If the pipettor is used daily it is recommended to clean/decontaminate
and check the performance of the pipettor every three months. Biohit
also provides complete repair and recalibration service for your pipettor
including a service report and performance certificate.
Note
: Please make sure that the pipettor has been decontaminated
before you send it to us or your local representative. Please advise if
any hazardous material has been used with your pipettor.
Note
: The use of the tip cone filters may prolong the interval of the
service. Change the filters regularly.
Note
: It is recommended to always use gloves when cleaning the
pipettor.
10.1. Daily cleaning of the outer surface of the pipettor
Your Biohit
m
LINE pipettor should be checked every day for
cleanliness. To clean and decontaminate the outer surface of your
pipettor use Biohit Proline‚ Biocontrol (Cat.no. 724004, 5 litres) and a
soft lint-free cloth. It is also possible to use ethanol (70%), isopropanol
(60%) or a mild detergent as a cleaning agent.
Gently clean the surface of the pipettor with moistened cloth and wipe
dry. Pay special attention to the tip cone. Change the tip cone filter if
needed (Chapter 7.3.)
10.2. Cleaning and decontaminating the lower part of the pipettor
If your pipettor is in daily use it is recommended to clean/decontaminate
and grease the pipettor every three months. It is recommended to send
the multichannel pipettors to your local Biohit service representative for
cleaning and greasing. To clean and decontaminate the lower parts of
the single channel pipettor, follow these steps:
