The Bohlin Gemini HR nano is the latest flagship rheometer from Malvern Instruments, offering advanced technology that is simple and straightforward in operation.
The instrument enables the measurement and control of nano-torque levels enabling users to probe weak or sensitive material structures, yet retains a continuous torque range to 200mNm.
The patented Rotonetic 2 drive technology brings an unsurpassed range and sensitivity to control torque and speed across all steady, dynamic and transient modes. This enables Gemini HR nano Rheometer to perform perfect strain controlled tests, as well as all stress controlled tests.
The Bohlin Gemini HRnano is a high performance, modular rheometer system, with a wide range of measurement geometries and accessories. EasySwap™ temperature controllers include integrated Peltier devices, a forced gas oven with optional liquid nitrogen cooling, electrical heating and a range of fluids circulators. The Gemini HR nano can be quickly and easily configured to allow testing across a full range of materials and applications.
