Apart from general care and occasional discharging (when the battery symbol starts flashing)
and recharging of the pipette, no special maintenance is necessary if the pipette is used
correctly. For information on charging the battery pack when the pipette is stored for a long
period, see Sec. 3.3. The lower part of the pipette may be replaced completely. (see Sec. 6.2.)
The process for replacing the seals in the lower part is described in Part B: "Ordering
information/service parts". Maintenance on the Research pro may be carried out by the Service
Department. If you require maintenance work, send your pipette to your authorized distributor.
The current addresses of our marketing partners can be found on our home page at http://
www.eppendorf.com.
In the case of the lower parts of the eight- and twelve-channel models, it is necessary to replace
the O-rings (seals for pipette tips), which means that the lower part must be unscrewed. A tool
for replacing the O-rings is contained in the accessories package:
With the 1,200 µL version, the O-ring is severed by pressing the tool firmly onto the nose cone.
The O-ring is removed. The new O-ring can be attached without any assembly aids.
Information: Only O-rings made of red silicone are now available for the Research Pipettes. The
force required for fitting or ejecting pipette tips has been further reduced with these red O-rings
- in comparison with the previous black O-rings. Uniform alignment of the pipette tips on the
lower part of the multi-channel model has also been improved. It is no longer necessary to
relubricate the red O-rings.
If the Research pro is to be checked, repaired or calibrated by Eppendorf AG or
another service partner, it must be free of hazardous substances and clean!
A form called "Decontamination certificate for return of goods" and general notes about
decontamination are available on our home page: www.eppendorf.com
A signed decontamination certificate must be enclosed with the pipette when it is returned.
The serial number of the Research pro must be entered on the decontamination certificate.
The serial number becomes visible on the housing of the Research pro when the ejector is
operated.
The bottom part of the Research pro can be decontaminated of potentially infectious
substances by being steam-autoclaved (see Sec. 6.2). The surfaces of the pipette can be
disinfected with alcohol (ethanol, propanol) or with a disinfectant containing alcohol.
–
Press opening A of the tool over the nose cone. The
sharp edge in the opening of the tool fits together with
the O-ring.
–
To cut the O-ring, press the tool heavily against the nose
cone. The tool and the O-ring are then removed.
–
Put the assembly aid (a shortened pipette tip) onto the
nose cone and slide the new O-ring onto the nose cone.
