CycloGraph & AccessoriesKey Features of theCycloGraph• Variable speed control (100-1400 RPM)CycloGraph with RAVE technology(Radially Accelerated Variable Engine)The CycloGraph system is a centrifugally accelerated device forperforming preparative thin layer radial separations. The separations occurquickly (within 20 minutes) with no need for scraping separated bands aswith traditional Thin Layer Chromatography.• Integrated 4 watt UV lamp forhands-free viewing of separations• ON/OFF switches for motor andUV lamp• Adjustable plane angle setting(0-45 degrees)• Solvent pump with associated ON/OFFpump control switchPrinciple of OperationThe compound to be separated is applied as a solution inside theadsorbent ring of the pre-cast Rotor (Analtech’s prepared consumable forthis device) by way of a solvent pump or hand held syringe. The chosensolvent mixture is then pumped (at an appropriate speed) through theadsorbent layer effectively separating the individual components as aresult of their different affinities for the layer and solvent mixture. As theindividual rings reach the outer rim of the Rotor they are spun off the edgeof the glass and collected in the special circular trough. The angle of thetrough allows the eluent to collect at the bottom and drip out the collectionport.• Ultra quiet and accurate low flowsolvent pump (0-30ml/min)• Compatible with all commonchromatography solvents includingacetic acidStandard system includes:• CycloGraph instrument• Solvent pump with tubing• Vial of Rotor Test Dye• Instruction manual• One year warrantyCheck out a videodemonstration of theCycloGraph atwww.analtech.com34
