GX-274 Liquid Handler
This small footprint, medium capacity liquid handler and autosampler offers small-to-large volume injection, fraction collection, and liquid handling capabilities. The VERITY® GX-274 Liquid Handler increases the throughput and efficiency of liquid transfers, serial dilutions, and other common tasks by processing up to four samples in parallel.
Increased Automated Throughput
Experience full automation of your HPLC workflows and get results more quickly. When the four-probe Z-arm is paired with two VERITY® 4220 Dual Syringe Pumps, each of the liquid handler’s four channels can accommodate unique syringe volumes, increasing your flexibility in many common liquid transfer tasks.
Increased Versatility
The VERITY GX-274 Liquid Handler features on-bed reservoirs that allow access to up four solvents without using a position on the bed. Transfer ports also allow access to two additional large volume solvent reservoirs without taking any bed rack positions, a capacity that can be extended with a VALVEMATE® II Valve Actuator. The rinse station design minimizes cross-contamination and provides two sets of transfer ports. The liquid handler design supports the use of Code 200 or Code 34X Series Racks.
