Vortex Mixer - Variable Speed Lab Vortexer - 1000-2800 rpm - 3 mm Orbit, Touch or Continuous

The Master Science Variable Speed Vortex Mixer uses eccentric rotation to create a vortex in test tubes and other small containers, mixing solutions quickly and thoroughly, including liquid clinging to the tube wall. It handles tubes up to 50 ml and, with optional adaptors, a wide range of other vessels.

Speed is adjustable from 1000 to 2800 rpm with a 3 mm orbit, and the unit works either in touch mode, running only while a tube is pressed on the head, or continuously with a digital timer. Because nothing enters the sample, the Master Science Variable Speed Vortex Mixer avoids contamination and magnetic-field effects from stir bars.

Problems the Master Science Variable Speed Vortex Mixer Solves

Hand shaking is slow and inconsistent. The Master Science Variable Speed Vortex Mixer helps with:

• Incomplete mixing: A strong vortex brings down and mixes liquid from the tube walls.
• Contamination from stir bars: Mixing happens without inserting anything into the sample.
• Different tube sizes: Sponge modules hold various tubes securely.
• Inconsistent run times: The digital timer standardises mixing time.
