Gilson FC 203B Fraction Collector
The Gilson FC 203B Fraction Collector is a compact, low-pressure fraction collection system designed for routine chromatographic applications where reliability and straightforward operation are required. It is commonly paired with the MINIPULS 3 pump and is suitable for use with FPLC, flash chromatography and other fractionation systems. The instrument supports both standalone operation and software control via TRILUTION LC, allowing flexible integration into existing laboratory workflows.
Designed to fit easily within most fume hoods, the FC 203B accommodates a range of collection formats, including test tubes and microplates, while maintaining a small footprint. Configuration options such as an optional diverter valve and multicolumn adapter enable tailored fraction collection based on time, volume, or detector signal, making the system suitable for laboratories processing fewer than 100 fractions per day.

Features
- Model Variants Available – Supplied as FC 203B (part number 171011-GIL) or FC 203B with integrated 3-way diverter valve (part number 171011DV), allowing selection based on collection method requirements
- 3-Way Diverter Valve – Enables diversion of void volumes, equilibration phases, or non-relevant peaks to waste; required for peak detection or time-window-based collection
- Application Scope – Suitable for laboratories collecting fewer than 100 fractions per day
- Flexible Collection Formats – Holds one rack accommodating up to 128 fractions (12 × 75 mm tubes), up to 105 fractions (13 × 100 mm tubes), or one shallow- or deep-well microplate
- Standalone or Software-Controlled Use – Can operate independently or be controlled through TRILUTION LC software for method-driven collection
- Multicolumn Collection Capability – Optional multicolumn adapter allows parallel fraction collection from up to eight channels
- System Integration – Multiple input/output contacts support easy integration with a wide range of chromatography systems, including FPLC, flash chromatography and HPLC
- Compact, Fume Hood-Compatible Design – Small footprint allows safe operation when handling hazardous materials
