3 PROGRAMMING OF THE FRACTION COLLECTOR
A short video on programming the OMNICOLL fraction collector can be found at

3.1 Principle of programming
Laboratory practice shows that programming of instruments equipped with microprocessors
is not simple and mistakes are easily made, especially when such instruments are used
occasionally.
We have developed a new method, which should eliminate such problems and make the
programming easy for all types of tube racks.
Figure 3.1-1
Magnetic coding band used for the
fraction positioning.
Figure 3.1-2
The fraction positions are indicated
by white lines drawn on the black magnetic
coding band as shown.
The white lines should be about 2 mm broad and full-length. These lines are detected by the
photo-detectors of the OMNICOLL fraction collector and the fraction collector stops at these
positions. The actual fraction position is about 1 mm after the first edge of the white lines.
Figure 3.1-3
The beginning and the end of a
row are indicated by short lines (about half the
length of the normal stripes or less and ~5 mm
broad) made on the lower edge (for the
beginning) and upper edge (for the end) of the
coding band, respectively.
Figure 3.1-4
The distance between the fraction
rows is programmed in a similar way. If you wish
to switch off the collector automatically after the
last row, draw the last line broader (approx. 1
cm)
