The resulting wide gap between the bob and the vessel’s wall is assumed to be infinite.
Rotational viscometers cover a very wide measuring range. Sample Typical sample volume for manual operation: Tests are performed at ambient temperature. Viscosity measuring range – for a model for medium viscosity materials, with several different spindles: Still, thermostat baths are available that can hold even a mL beaker.
Rotational Viscometer / infinite-gap geometry :: Anton Paar Wiki
Product Detail – ASTM-D2393-86
Rotational viscometers are the widest spread viscometers on the market and can be found in more or less all industries independent of company size. A great number of standards is available for rotational viscometers, among them for example: Temperature control Rotational viscometers that test typically mL of sample in an open beaker are in most cases operated without temperature control.
Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: We offer typical values which are based on the values in brochures and standards but are not related to specific instruments. Each viscometer model comes with a number of different measuring spindles.
Results provide reasonable repeatabilty but the absolute precision is not reliable due to inadequate temperature precision.
In addition, there are special sample adapters available for reducing the required sample volume, for extending the measuring range and for a wider temperature range. For systems that use a spring for measuring the torque, there are different models designed for different viscosity ranges. Performance Rotational viscometers cover a very wide measuring range.
The listed specifications apply to a typical instrument with spring mechanics and a classic cylinder or disc spindle in a large sample vessel. One spindle is suitable only for a part of the model’s measuring range. The viscosity calculation is based on this assumption.
