Extended rheometer range
Magna Projects and Instruments has extended its range of MiniCer benchtop capillary extrusion rheometers by introducing the high-speed H-option to allow piston speeds up to 1,500mm/min
The new H-option allows pressures up to 100 MPa (approx 15,000 psi) to be attained at temperatures up to 400C These powerful and compact instruments, for testing under typical process conditions the flow properties of materials such as molten plastics, foods, ceramic pastes, pharmaceuticals, are fully computer controlled using Magna's RheoTenax software suite, and allow testing to a standard template or full manual control

Evaluating the strain
Magna Projects and Instruments offers evaluation kits for Mantracourt's DSC digital strain card and D-cell digital strain puck for only £125 + carriage and VAT
Melt pressure transducers
The series 2000 melt pressure transducers, which require no traditional transmission-liquid filling of mercury or sodium-potassium, is now available online from Magna Projects and Instruments
All raw data are retained, and the package allows analysis of the flow data for power law fluids, Herschel-Bulkley and Bingham fluids (both with yield stresses present), wall slip, and others.
Additionally, RheoTenax has four analytical procedures for determining extensional viscosity, an extremely important parameter for many production processes.
MiniCer capillary rheometers are available in single- and twin-bore configurations, with barrels in nitrided tool steel, stainless steel, or in materials of choice.
Accessories are available for the determination of the pressure coefficient of viscosity, die swell, shear heating, and others.
A wide range of capillary dies is available for Magna's and other capillary extrusion rheometers, again in a choice of materials.
The MiniCer complements Magna's other instruments which includes the Eta 2100 and BFR 2100 floor-standing capillary extrusion rheometers, the NPLER extensional rheometer, the TTPT Tattersall two-point tester for the workability of fresh concretes and cements, the Imas in-line rheological analysis system for injection moulding machines, and the Mantracourt range of high-speed, low-noise digital signal conditioning equipment for process monitoring and control.
