GX-271 Liquid Handler

This small footprint, medium capacity liquid handler and autosampler offers small-to-large volume injection, fraction collection, and liquid handling capabilities. Its dynamic syringeless pumping system is capable of delivering microliters to hundreds of milliliters, with no change in hardware.

Innovative Injection Modules

This mid-throughput liquid handler can be configured with a Direct Injection Module for injection onto an HPLC or LC/MS system. An innovative injection port design that attaches directly to the injection valve reduces void volumes and minimizes carryover associated with calibrated connection tubing, allowing. injection volumes from 2 µL up to 25 mL.The continuous flow path design on all injection valves allows the system flow to continue even as the injection valve switches from load to inject, ensuring consistent pressure and flow.

Versatile, Space-saving Design

With a small footprint of only 23 inches of linear bench space and with a mid-size bed capacity, you’ll have the perfect blend of size, performance, and capacity. On-bed reservoirs provide access for up to four solvents without utilizing a position on the bed. The modular design supports the use of Code 20, 200, or 34X Series Racks and easily accommodates a variety of tubes, vials, and microplates.
