The GX-241 Liquid Handler provides large or small volume injection with automatic fraction collection using tubes, vials, or microplates in a small footprint, taking up less than 39 cm (16") of bench space.

A compact workhorse that provides the perfect balance of size, performance, and capabilities to individual labs!  Ideally suited for applications and labs where bench space is at a premium, the GX-241 Liquid Handler features a large injection volume range of 1 µL to 5 mL using a minimal dead volume direct injection design. The GX-241 also features two transfer ports for delivering sample to off-bed detection devices in Flow Injection Analysis (FIA). This two rack capacity liquid handler has the ability to hold hundreds of samples ranging from 2 mL vials to 100mm test tubes. The flexible platform can also hold up to 4 shallow or deep well 96 well microplates.
