15 Position MICROVAP
Nitrogen Evaporator


The 15 position MICROVAP benchtop evaporator is intended for small batch solvent evaporations, such as concentrations of sample groups in microcentrifuge tubes. It offers an effective and compact evaporation solution for samples in life science and pharmaceutical laboratories. 

Each MICROVAP uses minimal hood space while providing optimal temperature control for high and low boiling point solvents. The 15 position MICROVAP comes standard with stainless steel luer lock hubs and 4-inch x 19-gauge stainless steel needles for easy removal.

Up to 15 samples can be accommodated at once, and the instrument comes customized for one sample size with an outside diameter of 10-22mm. If multiple sample sizes will be used with the instrument, inserts can be purchased for each additional sample size.  

Each of the sample blocks and inserts are customized to your samples for a precise fit and optimum heat transfer.

Since these inserts and heat blocks are made-to-order, we will request that you deliver us three sample vials for each unique vial size upon placing an order for a 15 Position MICROVAP parallel evaporator. In situations where shipping sample vials to Organomation is not possible, we need precise measurements of your sample vials to be taken as illustrated in this guide.


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 temperature.
