To connect dialysis cell 42 to the IC system proceed as follows (see
also Fig. 21):
Capillaries fitted with new connectors must have a perfectly flat cut
surface. Use the 6.2621.080 Capillary cutter available as an option
to cut capillaries.
Connections for sample solution
1 Attach pump tubing to 833 Liquid Handling Pump
Unit
• Attach the two pieces of pump tubing 6.1826.040 (black-
black stopper) as described in Section 3.2 to the 833 IC
Liquid Handling Pump Unit 833, see Fig. 7.
2 Connect aspiration capillary for sample
• Attach one end of aspiration capillary 16 (6.1803.040; L =1
m) to PEEK coupling 18 on the suction side of the black-
black pump tubing of channel 1 from the 833 Pump Unit
using a PEEK compression fitting 17 (6.2744.010) (see Fig. 7
and Fig. 21).
• Immerse the other end of aspiration tubing 16 in the sample
container and fix it in position.
