Automated laboratory extractor DRQ

solid-liquid

Overview
RayKol DRQ Automated QuEChERS Extraction System is a benchtop automated sample-preparation platform designed for the QuEChERS workflow. Its compact hooded enclosure saves fume hood space and allows flexible placement. The system operates unattended after sample weighing and automates liquid dispensing, homogenization, shaking, centrifugation and layer separation.

Key features

• Continuous batch processing — up to 60 samples per run
• Fully automated QuEChERS workflow
• Efficient dual-channel capping module (≤3 s per cap)
• Solvent adding: 6-channel syringe pumps, 25 mL, <±1% RSD
• Layer separation with sensor detection, ≤±2% RSD, using disposable pipette tips
• Homogenizer bead dispensing: 0–99 beads per cycle
• Vortexing up to 3500 rpm; vertical shaking up to 1000 rpm (30 mm amplitude)
• Centrifuge up to 5500 rpm, optional cooling
• Built-in touch-screen control software
