GX-281 Liquid Handler – for Injection, Fraction Collection and Re-injection

The new GX-281 Liquid Handler features a revolutionary solvent delivery system: there are no syringes to replace or change to accommodate various volumes and flow rates. The Solvent Delivery System features an innovative technology that allows for a large dynamic range of 5 µL to 100 mL and flow rates of 1 µL/min to 25 mL/min.

Cat. No. GA-2603601

Features:

Revolutionary new Solvent Delivery System with integrated solvent selection of up to 5 solvents: No syringes to replace or change to accommodate different volumes and flow rates; allows for immediate access to up to 5 solvents and provides a large dynamic volume and flow rate range
Continuous flow path design on all injection valves for flow rates up to 200 mL/min: Allows system flow to continue even as the injection valve switches from load to inject, ensuring a more consistent pressure and flow
Direct Injection Module features an injection port that is integrated into the valve: Removes a source of potential carryover; reduces rinsing times, sample waste and X/Y travel for quicker injection cycle times
Enhanced bed capacity over other similar liquid handlers—uses only 33" of linear bench space: Holds up to six Code 200-Series racks with an efficient bed design
Separate injection and collection pathways: Ensures that fractions are never contaminated from the injection process
New rinse station system includes a high-flow rinse pump: Provides fast and efficient probe cleaning with up to 6 rinse solvents
