Gilson GX-271 ASPEC

Gilson GX-271 ASPEC

Flexible SPE and precise liquid handling that can be integrated with HPLC – all in one convenient package

The innovative mobile racks allow you to automate sample preparation steps before or after SPE, and the unique sealing caps allow for positive pressure extractions, which are more precise and robust.


The single probe Gilson GX-217 ASPEC is a complete solution for your SPE workflow.  With the optional GX Direct Injection module, the GX-271 ASPEC can even prepare samples and inject them directly on to your Gilson HPLC system!  With so many racks and accessory configurations, the Gilson GX-271 ASPEC is one of the most versatile SPE instruments in any lab.

Whether your application is pharmaceutical, clinical, forensic, or environmental, SPE has become the technique of choice for sample cleanup, sample prep, and trace analyte enrichment due to its inherent versatility, selectivity, speed and low solvent usage. Designed with today’s laboratory in mind, the GX-271 ASPEC™ has large cartridge capacity while minimizing its linear bench space footprint. System pressure is constantly monitored by a pressure sensing module to provide error handling for over pressurization as well as to monitor real-time cartridge pressures. Carryover and cross-contamination concerns are minimized with the use of Gilson’s revolutionary jet wash rinse stations. The GX-271 ASPEC combines the throughput and reliability to run unattended making this instrument an ideal choice for SPE, sample prep, sample clean up and GPC / SPE applications.
