With liquid ends made of durable, lightweight materials new mechanical designs, the XLS+ offer unique advantages over other multichannels. Reduced weight (up to 35% less than previous models), lighter pipetting forces and reduced peak tip ejection forces make the XLS+ easy to use, even for the most strenuous tasks. The sealing system minimizes “piston stickiness,” providing greater control, particularly with applications that require slow, careful pipetting. Sophisticated mechanical designs ensure high performance, and superior channel-to-channel consistency.
