Fraction collector OMNICOLL

fraction collector
  • Delivers fractions in tubes of all sizes and in any existing rack and so is compatible with the most racks on the market.
  • Collects unlimited number of fractions. Several racks supports can be combined and connected together.
  • Very easy programming of rack and tube position.
  • Fractionation according to time (0.1 to 999.9 min) or volume (0.01 to 500 ml). A pause (0.1 to 999.9 min.) between fractions can be programmed. Washing of tubing between to fractions is also possible.
  • The same sample can be distributed in more tubes at the same time.
  • Can easily be placed in a thermostabilized container.


  • the only fractions collector which can be easily programmed for any rack or recipients according to your choice
  • all electronical and mechanical components have been miniaturized and placed in one moving part, which is placed above the fractions, therefore, there is no danger of spilling and the lower part of the collector may be placed into a cooled air or water bath
  • modern microprocessor system using several optical sensors, which register stop signals and collect fractions according to time or volume
  • only the liquid conducting tubing is moved instead of the tubes, this requires much less energy and allows the fractions collector to be miniaturized
  • the lower part of the fractions collector can be used for carrying or storage of fractions
  • new plastic fixing plate allows fixation of any rack or recipient to the collecting surface of the collector
  • the highest safety for user has been attained by supplying OMNICOLL with low voltage current (9 V/12 W). This allows also an easy field application of OMNICOLL
  • solid metal construction makes OMNICOLL insensitive to solvents
  • when not used, OMNICOLL can be easily dissembled and requires only a small storage space
  • an AUTOSTOP function switches off the collector and the fractionation after a selected rack or at the end of the range
  • flow-stop function during the change from one fraction to the next
  • practically no service required
  • since a pause (from 0.1 to 999.9 min) can be programmed between fractions, OMNICOLL can be used for taking samples (during fermentations, biological or chemical processes). Washing of tubings between samples is possible.
  • remote control allows sampling after reception of an external signal, such as an alarm. In this way it is possible to obtain important samples during long processes running even during the absence of supervisor. There is also the possibility to connect a computer with a RS232 inerface (option). A program for remote control is available.
  • linear or meander like collection
  • up to 18 fractions/columns can be taken simultaneously
