New Gilson GX-271 & GX-274 ASPEC™

The Ultimate Solution for Automated SPE Introducing the new Gilson GX ASPEC Instrument range for automated solid phase extraction, now available from Anachem. Designed for today’s laboratories in mind, these instruments have large cartridge capacities with minimized bench space utilization and pressure sensing modules to ensure constant system performance. The revolutionary JetWash rinse stations vastly reduce concerns regarding carryover and contamination and combining throughput with the ability to run unattended the GX ASPEC is the perfect choice for SPE, sample preparation and sample clean up. The GX-271 ASPEC is a single probe instrument that can be integrated with a GX Direct Injection Module for performing on-line injections onto HPLC or LC/MS systems. The integration of mobile rack technology enables users to perform liquid handling tasks as well as SPE and depending on the application required the multiple rinse stations with optional rinse pump creates multiple rinsing parameters. By incorporating the new 406 single syringe pump, pressure can be monitored via the sensing module allowing for the control of error conditions. The GX-274 ASPEC is a four probe instrument that has capabilities of processing up to four samples simultaneously, increasing high throughput and efficiency for cartridge based applications. The GX-274 uses two 406 dual syringe pumps to transfer liquids, process multiple samples and monitor individual flow paths via pressure sensing. This instrument also has on bed transfer ports that allow access to two additional large volume solvent reservoirs without using precious rack positions, a capability that can be extended through the use of a VALVEMATE II. Each instrument utilizes 1, 3 and 6ml SPE cartridges allowing access for up to four separate solvents and by using an innovative sealing cap technology based on positive pressure elutions, cartridges can be sealed, run and monitored separately. The GX modular design allows for the use of code 20, 200 and 300 series racks and both the GX-271 and GX-274 ASPEC are controlled using Gilson’s Trilution™ LH software.
