Microplate Evaporator


The single plate MICROVAP microplate evaporator is one of the most compact sample concentrators available, and it continues to meet the needs of the life science and pharmaceutical industries. This microplate concentrator is ideal for laboratories needing efficient solutions for the gentle evaporation of high capacity, low volume samples in 96-well microplates and 96-well deep plates. The gas delivery manifold offers continuous evaporation via 2-inch x 19-gauge stainless steel needles.

In order to evaporate solvents with a wide range of boiling points effectively, the digital temperature controls and solid aluminum heating unit provide uniform heat from room temperature up to 130°C with temperature accuracy of +/- 2°C. The newly redesigned heating unit allows excellent heat stability for low temperature applications. A version without heat is available for evaporations that will be performed at ambient temperatures.
