ASPEC® 274 with Two ASPEC® 4260 Dual Syringe Pump and Z-Drive

Overview ×

This ASPEC® system for positive pressure solid phase extraction (SPE) maximizes throughput by processing up to four samples in parallel. With its small footprint and multiple probes, it is the ideal choice for high-throughput SPE automation on cartridges. Combined with ASPEC SPE Cartridges, it generates reproducible and efficient sample cleanup for clinical, forensic, doping, food, and environmental testing labs.

Parallel Processing for Maximum Efficiency

Four-probe Z-arm enables processing of four samples in parallel, increasing throughput and efficiency.

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 cartridges and enable multiple fraction elutions per sample. The syringe pump manages volumes from 1 mL to 10 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.
