Gilson GX-241 Liquid Handler

GX-241 Liquid Handler

Small in size... BIG on performance and flexibility!

Introducing the GX-241 Liquid Handler. 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.
