GX-271 ASPEC

This ASPEC® system provides the ultimate in versatility by combining flexible positive pressure solid phase extraction (SPE), precise liquid handling, large bed capacity, and on-line integration with liquid chromatography (LC) systems. With its large cartridge capacity and small footprint, it enables unattended processing of a high number of samples per day for any SPE application, even those requiring multiple extractions. The dual syringe pump option and injection module allow for automation of any liquid handling protocol such as SPE, supported liquid extraction (SLE), liquid-liquid extraction (LLE), and gel permeation chromatography (GPC)/SPE, including LC integration. Combined with ASPEC SPE Cartridges, the system generates reproducible sample cleanup for clinical, forensic, doping, food and environmental testing, and research labs.

Positive Pressure for Reproducible Extractions
Positive pressure extraction with unique sealing cap design increases reproducibility from sample to sample. The syringe pump delivers accurate volume dispensing.

Smart Design for Maximized Performance
Mobile rack technology enables multiple fraction elution and extraction per sample, and additional sample preparation steps after SPE. Broad volume range with dual syringes pump option handles volumes as low as 10 µL for combined sample cleanup and liquid handling applications.

Intuitive Error Handling for Trusted Results
The syringe pump pressure-sensing module provides error handling for high cartridge pressure or clogged liquid lines and monitors pressure on each fluid path individually. Optional jet wash rinse stations minimize carryover and cross contamination.

Versatile Software Control for Optimized Productivity
TRILUTION® Software allows for multiple liquid handling applications such as LLE and SPE on the same ASPEC system. Optimize throughput and efficiency by processing samples in either batch or sequential mode. Multiple fraction elution allows you to automate and optimize method development.
