The GX-241 liquid handler is compact and suited for applications and labs where bench space is at a premium. The liquid handler features a large injection volume range of 1 µL up to 5 mL using a minimal dead-volume direct injection design. The liquid handler also features two transfer ports for delivering samples to off-bed detection devices in flow injection applications. The two-rack capacity liquid handler has the ability to hold hundreds of samples ranging from 2 mL vials to 100 mm test tubes. The platform, in addition to tubes and vials, holds up to four standard or deep-well 96-well microplates.
