FEATURES OF FRACTION COLLECTORS & AUTOSAMPLERS

LAMBDA OMNICOLL for safe handling and easy programming

Safe handling

The LAMBDA OMNICOLL fraction collector / autosampler prioritizes user safety with its low voltage operation and innovative design, ensuring minimal spill risk while maintaining optimal conditions for heat-sensitive samples in a robust, easy-to-clean construction:

  • The highest safety for the user has been attained by supplying fraction collector LAMBDA OMNICOLL with low voltage current (9 V / 12 W).
  • Only the liquid conducting tubing (i.e. sampling tubing) moves, instead of the recipient tubes, which in-turn requires much less energy and allows the fraction collector to be miniaturized.
  • All the electronic and mechanical components have been placed above the fractions, therefore, no danger of spilling and the lower part of the collector, for example: can be placed into a thermo-stabilized container or water bath, to maintain the heat-sensitive samples at low temperatures during sample handling.
  • Solid metal construction makes LAMBDA OMNICOLL insensitive to solvents and easy to clean/disinfect the external surfaces of the instrument. Thus, the fraction collector and autosampler could be used under sterile conditions.
  • The supplied plastic fixing mat helps to keep the desired racks or recipients in position, on the collecting surface of the fraction collector.

Programming and operation of fraction collector

  • Modern microprocessor system using several optical sensors, which register stop signals and time based or volume based fraction collection
  • Pauses (from 0.1 to 999.9 min and 1 to 9999 min, almost 7 days) can be programmed between fractions. Hence, OMNICOLL can be used for taking samples (single or multiples). 
    The pause function can be used also for an automatic startup of the fraction collection. Washing of tubing between samples is possible, as the number of fractions in a series can be chosen.
  • Fraction collection in lines, row or meander-like (zig zag)
  • An auto stop function switches off the collector and the fractionation after a selected rack or at the end of the range

Remote control, RS-interface and other parameter controls

  • Remote control allows sampling after reception of an external signal (parameter controlled auto sampling, such as an alarm, TTL, etc.).
  • LAMBDA OMNICOLL can be equipped with drop counter (1-9999 and 60-599940), inert valve, RS-232 for PC control and other accessories (optional)
  • With the remote control option, it is possible to obtain important samples during long continuous processes and even in the absence of laboratory personnel.

LAMBDA OMNICOLL + Laboratory peristaltic pumps = Autosampler

  • Using peristaltic pumps with LAMBDA OMNICOLL can be used for automatic sampling at regular time intervals during fermentation and other biological or chemical processes.
  • LAMBDA OMNICOLL automatic liquid sampler can be combined with LAMBDA peristaltic pumps or any third party multichannel peristaltic pump (if it can be controlled remotely by analog signals) on the market.
  • Peristaltic pump flow-stop function during the change from one fraction to the next and at the end of the run
