1.1 Assembling the fraction collector

The setup of the fraction collection - sampler, LAMBDA OMNICOLL is very easy - a short video of the installation can be found at www.youtube.com/watch?v=33J9U_2-b-o

Figure 1.1-1 Push the first tub-sheet into the slots on one of the
shorter side of the yellow support.
Figure 1.1-2 Push the second tub-sheet into the slots on another
shorter side of the yellow support.
Figure 1.1-3 Insert the black frame into the corresponding slots
of the yellow supports
Figure 1.1-4 Pay attention to proceed at the same speed on both
sides otherwise it will end up in blocking. The tub-sheet should not
slip out of the slots.
Figure 1.1-5 Fix both frames in position with four bolts.
Figure 1.1-6 Tighten it securely with the help of the provided
hexagonal key.
Figure 1.1-7 Push the metal rod through both fixation nuts on the
right side of the frame and fasten them with screws. If needed fix
the support plate on the metal.
Figure 1.1-8 Place the fixing mat in the support. When needed
clean the mat from dust and dirt with a humid cloth. Make sure that
the mat is dry before use.
Figure 1.1-9 Place the control unit just at the beginning of the gear
rails. The distance from the edge should be the same on the left
and right sides. The gear wheels of the control unit must engage
correctly in the gears of both rails. Be sure that nothing will disturb
the movement of the control unit during fractionation.
Figure 1.1-10 Connect the cable of the control unit of the OMNICOLL fraction collector and sampler to the cable of the power supply plug.


Available plug types: AU, EU, US, UK
Figure 1.1-11 Place the supplied magnet on the right inner side
of the frame to stop the fraction collection.
Figure 1.1-12 Place the tube rack on the fixing mat, so that the first tube is just under the tip of the tubing and the edge of the rack is parallel to the yellow frontal support.

1.2 Assembly of fraction collection tubing

(a) PTFE tubing (external diameter 1.8 mm)
(b) Fixing nut
(c) O-ring (1 x 1.5mm)
(d) Tubing guide

Figure 1.2-1 Place the magnetic tubing holder conveniently in the center of the fraction collector carriage and control unit.
Figure 1.2-2 Push the delivered PTFE tubing through
the pipe guide as shown.
Figure 1.2-3 Slide the O-ring on the PTFE tubing.
Figure 1.2-4 Push the tubing through the tubing guide and make
sure a few mm (≈ 5mm) of PTFE tubing reach out of the tubing
guide so that the drops form only at the tip of PTFE tubing.
Figure 1.2-5 Screw the pipe guide onto the tubing guide to such
an extent that the PTFE tubing does not move freely inside the
tubing guide. Do not screw more strongly than necessary!
Figure 1.2-6 Let the PTFE tubing pass through the magnetic tubing
holder. Fix the tubing guide, with the help of the adjusting screw in
the holder, on the moving arm of the fraction collector at a convenient
distance above tubes.

1.3 Connecting the drop-counter detector (optional)

The drop counter is an optional device which could be obtained on request.

Fractionation can also be done according to the desired number of drops in the fraction collector using the drop-counter.

Figure 1.3-1 Showing drop counter (detector) cable with the
communication module (Art. No.: 6929)
Figure 1.3-2 Connect the drop-counter (detector) cable to the
“DROP” socket of the communication module.
Figure 1.3-3 Partially unscrew the tubing guide holder screw (A), so that the tubing guide (B) can be rotated. Slightly loosen the nut (C), so that the PTFE tubing (D) can move freely inside the tubing guide (B). Screw the drop counter (E) on the lower end of the tubing guide (B). Tighten the tubing guide holder screw (A) until the tubing guide (B) does not move freely. Securely tighten the nut (C), to prevent the movement of PTFE tubing (D) inside the tubing guide (B). Fix the drop counter cable (F) to the tubing guide (B) with the help of Teflon or a spiral wrap, etc. Let the drop-counter cable (F) pass together with the PTFE tubing (D) through the magnetic holder (H).
Figure 1.3-4 Connect the power supply to the “POWER” socket
in the communication module.
