The PTR Series are compact variable-speed, variable-angle vertical rotators providing vertical rotation, reciprocation, and vibration.

  • 360° vertical rotation – creates long wave motion for mixing large particles
  • Reciprocation – creates long and medium wave motion for medium and large particles
  • Vibration – creates short wave motion for mixing for small particles
  • Pause

All actions may be set for continuous or timed operation, and individual phases may be linked together for absolute flexibility.

  • 360° vertical rotation, reciprocation, and vibration can be set for continuous or timed operation, or linked together in different combinations to ensure optimum mixing conditions for your application
  • Choice of two models – PTR-35 or PTR-60 – with different speeds and microtube capacities
  • Vertical rotation speed: 1 to 100 rpm
  • Reciprocal rotation: 1 to 90° turning angle
  • Vibration: programmable in a burst of 1 to 5 seconds
  • Very easy to operate, with the simple set-up of multi-segment programs via push buttons and the 2-line LCD status display, fully programmable sequence of functions, including pause
  • The capacity of up to 26 (PTR-35), 48 (PTR-60) microtubes, and a maximum rotating speed of up to 100 rpm.
  • An optional accessory platform for accommodating tubes of different diameters
  • The reliable and extremely quiet motor produces regulated and reproducible rotation throughout the speed range
  • Compact with a low profile and small footprint – fits neatly into the workspace
  • Suitable to be used in cold rooms and incubators


Suitable for 360° vertical mixing applications including immuno precipitations and other affinity matrix applications, prevention of blood coagulation, latex diagnostics. Used in a variety of applications, from hybridisation reactions, cell growth, soft extraction and homogenisation of biological components in solution as well as reactions for binding and washing magnetic particles.
