Evaporators and Manifolds

Vacuum manifolds are used to draw liquid through a filter or SPE plate into either a waste tray or a collection plate. The application of vacuum increases the speed at which samples can be collected. The MicroLute™ vacuum manifold from Porvair Sciences is precision machined from crystal clear acrylic (top plate) and acetal polymer (plenum chamber). Porvair´s vacuum manifolds are designed to take most filter and SPE plates manufactured to the ANSI/SLAS specification with long drip directors.
 

Microplate Blowdown Evaporators are used in sample preparation to remove fluids from well plates or vials. Faster than centrifugal evaporation, significant increases in sample throughput are achieved through advanced evaporator head technology and an innovative manifold design, which directly injects heated nitrogen into each individual well of the microplate simultaneously. The blowdown technique is not suitable for high boiling solvents such as DMSO and water.

Both MiniVap^® and MiniVap^®Geminimay be operated with a supply of clean, dry compressed air in place of nitrogen, if the chemistry allows. An in-line gas filter must be used in this case
