PREP 9100 State of the art Fraction collector for GC

Micro-Preparative techniques allows you to .......

Separate complexe mixtures and structural isomeres
Isolate impurities for identification or for use as standards
Collect components for further use e.g. NMR

The new PREP9100 System based on the SNIFFER 9100 System has been completely redesigned in order to fit to the future needs. The system now is available as a stand alone unit to be installed to any GC available on the Market. The PREP9100 System has been designed to be a dedicated Preparative System connected to any GC available on the market by using a flexible heated interface line to the preparative unit. The new Electronic- and Pneumatic design , based on the newest technologies allows the system to be as flexible as possible for the future needs and to protect your investements in the Laboratory.
