PS-M3D Variable Speed / Angle, Multi-Function 3D Rotator

Ideally sized for personal use, the Grant bio PS-M3D multifunction rotator provides all that is required for thorough mixing in flasks, dishes, petri dishes and boxes :

  • 3D rotation - creating long wave motion, best for mixing large particles.
  • Reciprocal 3D rotation - creating long and medium wave motion, best for mixing medium and large particles.
  • Vibration - short wave motion, best for mixing small particles.


Suitable for mixing applications in many different fields, with specific applications including: immuno precipitations and other affinity matrix applications, treatment of adherent tissue culture in small volumes, e.g. for trypsinisation, gel staining and destaining, antibody staining, washes, hybridisations, Southern blots, western blots, in situs.
