788 IC Filtration Sample Processor
21
Do not connect the dialysis cell with anything other than the
6.2744.000 PVDF compression fittings supplied. If 6.2744.010
PEEK compression fittings are used, stress cracks may appear in the
ultra-filtration cell !
3 Connection pump tubing 10 – ultra-filtration cell
x Mount a PEEK compression fitting 6
666 on the end of the PTFE
capillary 24 24 24 24 and screw it on to coupling 19 19 19 19.
x Mount a PVDF compression fitting 22 22 22 22 on the other end of the
PTFE capillary 24 24 24 24.
x Screw this PEEK capillary with the PVDF compression fitting
to inlet opening 48 48 48 48 of the bottom part of the cell (see Fig. 9).
x Push coupling 19
19 19 19 on to the outlet end of the pump tubing 10 10 10 10
(yellow/yellow) (see Fig. 10).
4 Connection ultra-filtration cell – waste
x Mount a PVDF compression fitting 22
22 22 22 on the end of the PTFE
capillary 25 25 25 25.
x Screw this end of the PTFE capillary with the PVDF
compression fitting to outlet opening 49 49 49 49 of the bottom part of
the cell (see Fig. 9).
x Mount the other end of the PTFE capillary to a waste bottle
(e.g. optional: 6.1608.070 bottle with 6.1602.150 siphon
GL45).
5 Connection ultra-filtration cell – pump tubing 11
x Mount a PEEK compression fitting 6
666 on the end of the PTFE
capillary 21 21 21 21 and screw it on to coupling 19 19 19 19.
x Mount a PVDF compression fitting 22
22 22 22 on the other end of the
PTFE capillary 21 21 21 21.
x Screw this PTFE capillary with the PVDF compression fitting
to outlet opening for the filtrate 47 47 47 47 of the top part of the cell
(see Fig. 9).
x Push coupling 19
19 19 19 on to the inlet end of the pump tubing 11 11 11 11
(orange/yellow) (see Fig. 10).
6 Connection pump tubing 11 – injection valve
(Underlined numbers are parts or controls from the Instructions
for Use for the 733 IC Separation Center)
x Mount a PEEK compression fitting 6
666 on the end of the PEEK
capillary 20 20 20 20 and screw it on to coupling 19 19 19 19.
x Push coupling 19
19 19 19 on to the outlet end of the pump tubing 11 11 11 11
(orange/yellow) (see Fig. 10).
x At the 733 IC Separation Center, loosen the rotary nipple
screwed onto the interior side of connection 22 22 22 22 or 28 28 28 28.
x Take PTFE suction tubing 84
84 84 84 (see Fig. 14 and Fig. 15 of the
732/733 Instructions for Use) completely out of connection 22 22 22 22
or 28 28 28 28 and unscrew from connection "1" of injection valve 66 66 66 66.
