Visiprep™ manifold cover (flow control valves and gasket included) is a solid phase extraction vacuum manifold, which allows to continuously process up to 24 solid phase extraction (SPE) tubes. It provides an accuracy in flow control through each solid phase extraction tube by rotating the independent, screw-type valves, thus it ensures that the packing will is not dried in some of the tubes while others finish draining. It also helps in preventing the PTFE solvent guide running through each valve from resting on the work surface and becoming contaminated or damaged.
