MICROVAP Nitrogen Evaporator Configurations and Options

MICROVAP laboratory evaporators are Organomation’s most compact and affordable nitrogen blowdown instruments and are recommended for users with small sample sizes and limited bench space.  This product line includes 4 different models.  Single micro-titer instruments hold one 96 well plate, while the triple micro-titer model holds 3 microwell plates.  For evaporating sample tubes, there are two models which can concentrate up to 15 or 24 vials at one time.


Heating Unit

  • Dry block: All MICROVAP evaporators come with dry block heating.  The 15 and 24 position instruments have dry blocks with or without inserts that are custom drilled to fit the customer's sample tubes for optimum heat transfer. The single and triple microplate instruments have flat heating plates to heat a 96 well plate.
  • Bath for Flammable Solvents (-Z option) is recommended for use with flammable solvents, and as such it is offered for labs that work with highly flammable materials.  The Z-purge (-Z) reduces the classification from Division 2 (Zone 2) to unclassified/nonhazardous.  Purging is a world-wide accepted protection concept from explosion.  Explosion protection is achieved by keeping the potentially explosive atmosphere away from any source of ignition.  A small flow of nitrogen into the bath pan creates a slight positive pressure gradient inside the bath case. As the nitrogen leaks back out, the bath is continually purged. Highly flammable materials such as petroleum ether, ethyl ether and acetaldehyde should not be used unless the Type-Z Purge intrinsically safe bath option is installed and running.



  • We sell instruments all over the world, and therefore we can build your instrument for the correct wiring for your lab, no matter where you are located.  Wiring other than the standard US 110v requires cat# -2 option.  There are many different types of plugs.  North America, Europe, China and India all have their own type of plug--- and we can build them all.



Pasteur Pipet Adaptors:

  • For those that would rather use their own pipets rather than needles, pipet adaptors (NA0636 or NA0637) make pipets compatible with 15 and 24 Position MICROVAP evaporators.  Because Pasteur Pipets are considered disposable, this option is for those looking for their nitrogen blowdown vehicle to have a one-time use option.  Pipet adaptors are not compatible with the microplate instruments.
