Gilson - ASPEC 271 Dual Syringe System

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, supported liquid extraction (SLE), liquid-liquid extraction (LLE), and gel permeation chromatography (GPC)/SPE. The dual syringe pump allows for automated internal standard addition or partial loop injection. 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 and full control of sorbent drying.

Smart Design for Maximized Performance
Large bed capacity for processing up to 144 samples unattended. The mobile racks accommodate 1, 3, and 6 mL SPE polypropylene and glass cartridges and enable multiple fraction elutions per sample. The dual syringe pump manages volumes from 10 ?L to 25 mL with high accuracy and precision, allowing the transfer of eluted fractions in sealed injection vials or directly in the LC system with the optional GX direct injection module.

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 enables liquid handling and SPE applications 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.
