Gilson ASPEC 271
The Gilson ASPEC 271 system is an automated sample preparation platform designed for positive pressure solid phase extraction (SPE) and advanced liquid handling workflows. It supports a wide range of extraction techniques, including SPE, supported liquid extraction (SLE), liquid–liquid extraction (LLE), and gel permeation chromatography (GPC)/SPE, with optional on-line integration to liquid chromatography (LC) systems. The system accommodates large cartridge bed volumes within a compact footprint, enabling unattended, high-throughput processing and methods that require multiple cartridge extractions. Dual syringe pump configurations allow accurate handling of volumes from microlitre to millilitre scale, supporting both sample clean-up and precise reagent delivery.
Reproducibility is enhanced through positive pressure extraction and a sealing cap design that ensures consistent flow across samples, while pressure-sensing technology monitors each fluid path to detect blockages or abnormal cartridge pressure. Mobile rack technology enables multiple fraction collection and additional preparation steps within a single method, extending flexibility for complex workflows. Optional jet wash stations help reduce carryover and cross-contamination. System operation is controlled through TRILUTION software, which supports sequential or batch processing, multi-fraction elution, and method development across different extraction techniques, making the ASPEC 271 suitable for clinical, forensic, food, environmental, and research laboratory applications.
