3 Connect dialysis cell
• Screw PTFE capillary 57 (6.1803.040; L =1 m) (23 in Fig. 7)
to PEEK coupling 21 (6.2744.034) on the delivery side of the
pump tubing with the black-black stoppers of channel 1
from the 833 Pump Unit using a PEEK compression fitting
17 (6.2744.010) (see Fig. 7 and Fig. 21).
Lead the other end of the capillary through one of the
feedthroughs 14 at the front or the side of the 820 Separation
Center in the column compartment and screw it on to inlet
opening 51 of lower part 46 of the dialysis cell using a PVDF
compression fitting 64 (6.2744.000) (see Fig. 15 and Fig. 21).
• Screw PTFE capillary 58 (6.1803.040; L =1 m) to outlet
opening 52 of lower part 46 of the dialysis cell (see Fig. 15)
using a PVDF compression fitting 64 (6.2744.000) and lead it
out of the column compartment through one of the
feedthroughs 14 on the front or side of the 820 Separation
Center. Attach the other end of the PTFE capillary 58 to PEEK
coupling 18 on the suction side of the black-black pump
tubing of channel 2 from the 833 Pump Unit using a PEEK
compression fitting 17 (6.2744.010) (see Fig. 7 and Fig. 21).
Use only the above-mentioned 6.2744.000 PVDF compression
fittings for the dialysis cell connections. If 6.2744.010 PEEK
compression fittings are used then stress cracks could occur in the
dialysis cell !
4 Connect waste container
• Screw PTFE capillary 59 (6.1803.040; L =1 m) (23 in Fig. 7)
to PEEK coupling 21 (6.2744.034) on the delivery side of the
pump tubing with the black-black stoppers of channel 2
from the 833 Pump Unit using a PEEK compression fitting
17 (6.2744.010) (see Fig. 7 and Fig. 21). Lead the other end
of the capillary into a sufficiently large waste container and fix
it in position.
Connections for acceptor solution
1 Connect pump tubing to 833 Liquid Handling
Dialysis Unit
• Attach the two pieces of pump tubing 6.1826.030 (orange-
yellwo stopper) as described in Section 3.2 to the 833 IC
Liquid Handling Dialysis Unit 833, see Fig. 7.
2 Connect aspiration capillary for acceptor solution
• Attach one end of aspiration capillary 16 (6.1803.040; L =1
m) to PEEK coupling 18 on the suction side of the orange-
yellow pump tubing of channel 1 from the 833 Dialysis
Unit using a PEEK compression fitting 17 (6.2744.010) (see
Fig. 7 and Fig. 21).
