FC 203B Fraction Collector

FC 203B Fraction Collector

***This item has been tested for basic functionality.

The Gilson FC 203B Fraction Collector is an ideal compact fraction collector for a wide variety of collection samples, including microplates, vials, and tubes. Built-in keypad makes setup and operation simple and efficient, with easy connection to your HPLC system. Fractions can be collected by time, drop, or peak to suit your chromatography conditions.
