Yamato Mini Rotary Evaporator for Research and Development

    • Rotate faster & slower (315 rpms – 5 rpms) than any other rotary evaporator on the market, so you can test new SOPs and develop better methods.
    • Easily manage your expensive samples with small flask sizes (from 100ml to 2L).
    • Program rotation direction changes, ramps, and other automations to get more done in the lab at once.
    • Eliminate most manual steps in the sample drying and removal process by creating finer dry granules (ask us how).
    • Easily analyze the residue left over after distillation.
    • Orient for left or right-handed operation based on your limited bench space.
    • Easy operations with one-hand jack
    • 200mm stroke for convenient flask replacement

Why choose a mini rotary evaporator for R&D?

If you’re in process development, method development, or doing basic R&D, most rotovaps on the market aren’t actually built for you.

If your job is testing new recipes, why use an instrument that’s built to follow a recipe?

Yamato mini rotary evaporators are built specifically for process development, with a wider range of rotation speeds than any other rotovap on the market (at 5 to 315 rpms).

That’s about 15% more range than any other rotary evaporator.

And a more appropriate flask size for your work, from a max of a 2L rotary evaporator flask down to 100ml.

Plus, you can program your test methods or SOPs into the system and walk away.

  • Spin forward at 15 rpms for 20 seconds
  • Spin backward at 15 rpms for 20 seconds
  • Repeat for 60 minutes

It’s the only one that lets you work out the best method for your new process without limitations.

Plus, depending on your model, these are priced 10-20% better than comparable models from the other names you know.

DigiVac’s Vapor Pressure Controller (VPC)

The DigiVac Vapor Pressure Controller allows you to determine set-points and maintain vacuum at that level. The vacuum regulator is particularly useful when you are looking to maintain pressure at a certain level as needed for botanical processing and rotary evaporation or ideal for any vacuum process that involves vapors. Mounting can be bench-top or on a laboratory pole.

  • Display of both the set-point and current vacuum control
  • Fine control of target vapor pressure for more precise compound separation through distillation
  • Flow path designed to be tolerant of harsh chemicals
  • UL, CE, CSA and RoHS Certified, Fully safety certified for USA, Canada and Europe
  • Includes 10ft 3/8 silicone hose to connect from VPC to Rotary Evaporator

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The process of rotary evaporation is most often used to separate solvents with low boiling points, such a n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure. However, careful application also allows for the removal of a solvent from a sample containing a liquid compound, if there is minimal co-evaporation (azeotropic behavior) and a sufficient difference in boiling points at the chosen temperature and reduced pressure.


Example: The following table is a list of a variety of substances ordered by increasing vapor pressure (in absolute units).

Safety Notice

Your safety is important to us! Please use caution when operating. Users of glass reaction equipment must take all necessary precautions to avoid contact with rotating parts, particularly entanglement of loose clothing, hair, necklaces, or other jewelry. Under these circumstances, the winding action of the rotating parts can draw the user(s) into the apparatus, resulting in breakage of glassware, burns, and/or chemical exposure. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
