Fraction Collectors, the Retriever® 500 for Compact Simplicity
Overview
The Retriever 500 is a simple and compact fraction collector designed for column liquid chromatography, HPLC, and other applications involving measured collections of fractions.
Only the size of a notebook page, Retriever 500 still holds over a hundred tubes. More compact than other fraction collectors of similar or less capacity, the Retriever 500 takes minimal space in a HPLC or low-pressure LC system, and fits easily in a cramped cold room.
The Retriever 500’s multiple-rack, linear-movement configuration allows the removal of filled tube groups at any time. A special "stop" rack, color coded red, marks the end of the run, shutting off the collector and a connected pump. The simple, reliable drive mechanism uses only one motor and has been proven in over 30,000 similar Isco instruments. An infrared rack sensing device precisely locates when mixed racks are used or when racks are left out.
The Retriever 500 operates on 14 volts supplied by a wall transformer. A thin low-voltage cord passes easily by a refrigerator door gasket.
The Retriever 500 is also available in a complete isocratic LC system with pump and UV detector.
Fractions can be collected on the basis of time (5 seconds to 999 minutes), counted drops (1 to
999 drops) or other counted events (1 to 999) such as pump pulses.
Features of the Retriever 500 Fraction Collector:
Compact, only the foot print of notebook page, yet holds over a hundred tubes
Stationary drop former
Collect uniform fractions by time or drop count.
Multiple rack design lets you remove small groups of tubes anytime during a run.
Automatic pump shutoff
Protection against spills, automatically stops or diverts flow before each tube change, at the end of a run or during a power failure
