Gilson GX-271 Liquid Handler

The GX-271 Liquid Handler




The GX-271 Liquid Handler provides a small footprint, medium capacity liquid handler and autosampler offering small to large volume injection, fraction collection and liquid handling capabilities. This instrument can be configured with either a GX Prep or Analytical Solvent System which features a syringeless pumping technology capable of delivering a wide range of flow rates and volumes. Taking up only 23” of linear bench space with a mid-size bed capacity, the GX-271 is the perfect blend of size, performance and capacity. All injection modules feature a continuous flow path design for preparative flow rates up to 200 mL/min. The GX-271 can accommodate large injection volumes up to 25 mL with minimal sample waste and carryover.




The GX-271 Liquid Handler or autosampler can be configured with a GX Direct Injection Module for injection onto an HPLC or LC/MS system. The GX Direct Injection Module features an innovative injection port design that attaches directly to the injection valve reducing void volumes and minimizing carryover associated with calibrated connection tubing.
