Gilson 331 HPLC Pump

1x Gilson, 331, HPLC Pump

Description
Semi-preparative, multi-solvent pumps designed for use in Gilson's HPLC Systems
accommodating flow rates ranging from 0.15 mL/min to 30 mL/min at pressures
up to 8,700 psi (600 bar) and with columns up to 20 mm ID.
Dual-piston pumps for semipreparative and preparative chromatography.

Feature a variable-volume, dynamic mixer for optimized gradient performance.
• Milligram-level sample mass throughput per injection: >50 mg with a 20 mm ID column
• Easy linear transposition from analytical to preparative HPLC methods on a 4
to 20 mm ID column packed with high-efficiency stationary phases
• Solvent selection on each pump with optional four-solvent valve (up to eight solvents)
• Control from 331 Master Pump: flow-rate gradient, four-solvent selection
and step gradient (additional valve), composition gradient (one or two additional pumps),
sample-injection pump, UV/VIS detector, and electrical input/output contacts
with any other associated equipment
• Keypad control: safety files (pressure limits, emergency signal and power failure);
anomaly processing procedures with related outcomes; GLP functions: solvent consumption,
diagnostic helps, maintenance logs, leak test, piston seal installation, mixing test and audit trail
