Auto EVA mini Automated Nitrogen Evaporation System is specialized in the concentration of small-volume samples, it uses nitrogen gas flow and sample rack heating to perform rapid and stable evaporation. RayKol Auto EVA mini is compatible with commonly used microplates on the market, such as 96 shallow-well plates, 96 deep-well plates, 24 and 48-well microplates. The design in 96 nitrogen-blowing needles makes the flow from each nitrogen-blowing needle consistent and stable. The optional nitrogen gas heating module can accelerate evaporation in a microplate. Auto EVA 80 is also compatible with 2mL GC vials and 1 to 2mL centrifuge vials, which can be applied in fast evaporation of 2mL purification solutions in QuEChERS.
