Single Magnet Mixer

"For SPME and SPDE Applications"

What is a Single Magnet Mixer?

This unit is nothing more than an automated stirring plate, which rotates the magnet located in each vial at speeds of up to 750RPM (1500RPM option available). At the same time, it can be used to heat or cool your sample.


The most beneficial application of the Single Magnet Mixer is SPME immersed in liquid. When immersed in liquid, the SMM is gentle with the fiber and needle. The liquid is mixed by a small magnet inside the vial and creates a vortex at high speeds. Fiber lifetime is significantly increased due to the gentle mixing within the SMM.
