The GX-281 features a large bed capacity within only 35” of linear bench space. The revolutionary Solvent System is offered in a Preparative and Analytical versions providing flow rate and volume options ranging from nLs to 100s of mLs. The innovative GX Z-injection technology offers ideal injection performance for volumes ranging from uL to mL ranges with minimal extra volume. Gilson’s 15X Series UV/VIS detectors offer an interchangeable flow cell design making it suitable for applications ranging from analytical to semi-preparative flow rates. Add on the new prepELS Detector to any Gilson analytical or semi-preparative system for increased detection capabilities of any compounds or impurities lacking chromophores.

GX Z-injection Technology
GX Z-Injection Module features fast, low carryover /maintenance injections by aspirating the sample directly into the valve.

Low Mount Fraction Collection
Separate injection and fraction collection pathways eliminate contamination of fractions from sample injection.

GX-281 Liquid Handler
A single instrument for high throughput injection, fraction collection and re-injection – no need to transfer tubes or racks to another system.
