Superb Pumping Stability at Low Flow Rate - Optimum for Semi-microcolumn Analysis!
List of Sales Representatives Technical Materials
Metal-free Pump Head
The pump head is made of polyetheretherketone (PEEK) resin, allowing analysis of samples having high adsorption properties such as proteins or other physiologically active samples.
High Density Dual Plunger Driving
Flow volume of 9.42 µL per stroke. The internal pressure damper ensures a steady pulseless flow even at a low flow rate (flow rate range: 1-3000 µL/min). A precise gradient curve is drawn even by gradient analysis using multiple pumps.
Relationship between plunger position, dispensing rate, and pressure
Ultimate Reduction of Flow Pulsations (50% of conventional model)
Semi-microcolumns of 1.0 mm I.D. Also Available
BPA detection limit
Built-in Microcomputer for High-precision Control
Internal pressure damper renders a pulseless flow (flow rate range: 1-3000 µL/min). Accurate gradient mixing is possible at very low flow rates.
Accurate gradient curve at low flow rate
Stable Baseline (Semi-microcell)
Easy Operation by Numerical Input Keys
LCD panel-based operation is done via the ten-key control pad. Up to 50 steps can be set for flow programming (in 1 µL/min increments).
Networked System Control
Remote operation from a WindowsTM PC is possible by using Syscon-21 software.
Airtrap Included
An airtrap is built into the pump to prevent air from entering the pump head.
Redesigned Front Structure for Easy Operation and Maintenance (See the photo at right)
