Temperature control Rotational viscometers that test typically mL of sample in an open beaker are in most cases operated without temperature control.
Rotational Viscometer / infinite-gap geometry :: Anton Paar Wiki
Tests are performed at ambient temperature. For systems that use a spring for measuring the torque, there are different models designed for different viscosity ranges.
One spindle is suitable only for a part of the model’s measuring range. The easy filling of a simple sample container and the fast and easy exchange of the measuring bob make rotary viscometers the most versatile instruments, giving good results in various applications. Sample Typical sample volume for manual operation: Each viscometer model comes with a number of different measuring spindles.
Performance Rotational viscometers cover a very wide measuring range. Still, thermostat baths are available that can hold even a mL beaker.
The listed specifications apply to a typical instrument with spring mechanics and a classic cylinder or disc spindle in a large sample vessel. Rotational viscometers that test typically mL of sample in an open beaker are in most cases operated without temperature control. Rotational viscometers cover qstm very wide measuring range.
Viscosity measuring range – for a model for medium viscosity materials, with several different spindles: Density Redefined Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: Standards and Norms A great number of standards is available for rotational viscometers, among them for example: The higher the tested viscosity is, the stronger the spring has to be.
Rotational viscometers are the widest spread viscometers on the market and can be found in more or less all industries independent of company size.
Product Detail – ASTM-D2393-86
Results provide reasonable repeatabilty but the absolute precision is not reliable due to inadequate temperature precision. We offer typical values which are based on the values in d23933 and standards but are not related to specific instruments. A great number of standards is available for rotational viscometers, among them for example: Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: The resulting wide gap between the bob and the vessel’s wall is assumed to be infinite.
The viscosity calculation is based on this assumption.
