Mooney Viscometer

Get Latest Price

Features

Mooney Viscometer is a shearing disk Viscometer, designed for accurate measurement of viscosity, scorch time and cure rates of the elastomers.

The instrument consists of flat, cylindrical disk, driven by a motor to rotate slowly and continuously in one direction. This disk is embedded into elastomer specimen which is confined in a heated die cavity maintained at specified temperature and kept closed by a specified force. As the disk rotates its experiences a shear strain. This resistance to rotation offered by the elastomer is shearing viscosity which is proportional to mean absolute viscosity of the specimen.

Normally a preheat period is given to the elastomer following which the disk starts to rotate. An initial high viscosity is recorded and then as the viscosity also decreases, to a minimum value Viscosity obtained with large rotor are approximately twice those of small rotor.

The viscosity is reported as under:

  • Method of sample preparation
  • Mooney viscosity number
  • Rotor size
  • Preheat time
  • Time interval to viscosity reading
  • Temperature of test

Typical test results are stated as under: 50ML(l+4)100C

Where,

  • 50M = Viscosity in mooney units
  • L = Large rotor (for small replace it with 'S')
  • l =Preheat time in minutes
  • 4 = Time in minutes after starting the motor at which the reading is taken
  • 100C = Test temperature

Features of Software and Hardware

  • Cromtech India will provide a unit on the Mooney Viscometer which will interface between computer and Mooney Viscometer
  • Delete Option (Stock, Batch No.)
  • Provision Quality Gates (pass/ fail criteria)
  • Statistical Analysis (Sigma, Range, Mean, Standard Deviation)

On-line Solvent Degassing
Interested in this product?
Get Best Quote

Description
This on-line solvent degassing equipment is installed between the mobile phase reservoir and HPLC pump. The mobile phase solvent enters the degasser entry through permeable membrane tube placed in a vacuum chamber. Because of the pressure difference of the wall of the permeable membrane tube, the dissolved gas continuously leaks out of the tube thus causing degassing for the mobile phase solvents. The degassed mobile phase is then moved to HPLC pump entrance through the gas-proof tube.
