Viscosity Measurement

Viscosity Measurement: DV2T and DV3T

What is Viscosity?

Viscosity behaviour allows manufacturers to understand and gather precious information about their product: predicting its pourability, its performance in a dipping or coating operation, or the ease with which it may be handled, processed, or used. The interrelation between rheology and other product dimensions often makes the measurement of viscosity the most sensitive or convenient way of detecting changes in colour, density, stability, solids content, and molecular weight.

Is Your Viscometer 21 CFR Part 11 Compliant?

Viscometers are a crucial part of research, development, and process control programs. Especially in some industries, like pharmaceuticals or cosmetics, where being able to have full traceability of your processes is so important.

Having a 21 CFR Part 11 Compliant Viscometer and Software package can make your life much easier.

How Can Brookfield Ametek Make Me Compliant?

The Brookfield Ametek Touch Screen Viscometers and Rheometers (example: DV2T, DV3T and RST) are 21 CFR Part 11 Compliant.

Furthermore, the Brookfield Ametek RheocalcT Software boasts secure 21 CFR features including:

• Stored Test Methods re-run on instrument for repeatability
• Test Methods stored on PC for unattended operation
• Test Methods locked for modification by operator
• Multiple access levels
• Password access restrictions
• Digital signatures
• Data results storage in a password-protected database.

Why the DV2T & the DV3T?

The DV2T and the DV3T are very versatile, cost-effective and all-rounder instruments for measuring viscosity. They are the perfect choice for any research, development, and process labs.

The DV3T is a sophisticated Rheometer with Easy-To-Use Intuitive Controls. A 7-inch full colour touch screen conveniently displays all test parameters along with measured values for yield stress, viscosity and temperature. On screen graphing shows real-time test data which can be captured in stand-alone mode, recorded on a printer or sent to a PC.
Quick, straight-forward, single point viscosity is also easily accomplished with the DV3T making it the ideal "all-in-one" instrument for busy QC labs as well as demanding R&D departments doing comprehensive flow behavior.
