• Choice of six different collecting racks—four for standard mode collection and two for preparative (prep) mode. One 18/30 mm tube rack for standard mode collection is supplied with Frac-950. The others are optional accessories. • Two different methods for reducing spillage during tube change: DropSync or Accumulator.
• Operate in accordance with local safety instructions. WARNING! Pinch hazard. Do not have any part of your body within the unit base area when Frac-950 is switched on. An automatic calibration process starts when Frac-950 is connected to Pinch UNICORN.
To make it easier to move Frac-950 on the laboratory bench, first lift the front (approx. 30°) and tilt the unit until the rubber feet clear the bench.
The funnel-to-flask rack is actually the prep mode 30 mm tube rack but only 30 of the 80 holes are filled with funnels. Frac-950 is delivered with rack type 18 and 30 mm tubes. The other rack models are available as accessories.

Description Instrument Standard mode Prep mode Fraction Collector Frac-950 is an automated fraction collector for use in liquid chromatography as part of an ÄKTAdesign chromatography system. The fractionation base can be selected as time or volume. Collection vessel positions in a rack can be pre-programmed (using standard racks), or occupy any position within the fractionation area (new rack definition).
