SPECiFiCATiONS
PIPETMAN M Connected is a high quality pipette that offers excellent accuracy and
precision; it is fully compliant with ISO 8655 and is CE marked.
The figures given in the
Gilson Maximum Permissible Errors
Table 2 on page 32 were
obtained using “PIPETMAN DIAMOND Tips”. These figures are only guaranteed when
using genuine PIPETMAN DIAMOND Tips.
Each pipette is inspected and validated by qualified technicians according to the Gilson
quality system. Gilson declares that its manufactured pipettes comply with the
requirements of the ISO 8655 standard, by type testing.
Non-immersible Parts
1.
Wipe the handle of the pipette with a soft cloth or lint-free tissue covered with
the chosen decontaminant.
2. Wipe the handle of the pipette with a soft cloth or lint-free tissue covered with
distilled water.
immersible Parts
Only the following components can be immersed in a decontaminant solution:
●
Single channel models
a
tip ejector, tip holder (both parts), connecting nut,
piston (including holder), and guide.
●
Multichannel models
a
tip ejector, ejector locks, and ejector spacer.
Please note that although the lower part of PIPETMAN M Connected multichannel can
withstand a few number of autoclaving cycles, we do not recommend autoclaving it.
1.
Disassemble the pipette as described in Chapter 15
on page 22).
2. Immerse the components in the decontaminant solution or wipe them according
the intructions given by the manufacturer or supplier of the decontaminant.
3. Rinse the individual components with distilled or sterile water.

or soft cloth.
5. Lubricate the piston and reassemble the pipette according to the instructions
given in this chapter.

LEAk TEST
This test may be performed at any time to check that the pipette does not leak,
especially after performing a maintenance or decontamination procedure. If a pipette
fails this test, you should replace the faulty part (e.g., O-ring, tip holder) and repeat this
test, after making sure that the pipette is correctly reassembled.
1.
Fit a PIPETMAN DIAMOND Tip.
2. Set the pipette to the nominal volume.
3. Aspirate the nominal volume from a beaker of distilled water.
4. Hold the pipette in the vertical position and wait for 20 seconds.
If a water droplet appears at the end of the tip, there is a leak (refer to Chapter 18
on page 31)
If you see no droplet, re-immerse the tip below the surface of water.
The water level inside the tip should remain constant; if the level goes down then there is a
leak (refer to Chapter 18
on page 31)
For multichannel models, check if the water level between each tip is the same.
