DVNext Rheometer

The DVNext Rheometer is AMETEK Brookfield’s latest model that incorporates new advanced features that our customers have been asking for with the repeatability and reliability you expect from us. It is an easy-to-use, stand-alone instrument for measuring viscosity, gel time, and yield stress. It is available in a Standard version and a 21 CFR Part 11 Compliant version

The DVNext Rheometer with Gel Timer Functionality measures gel time using unique magnetic coupling that attaches the glass rod to instrument. When gel time is reached, display shows both gel time and equivalent viscosity value. The glass rod is quickly and easily detached from instrument. Integrated temperature probe provides peak exotherm data if needed. The DVNext can be ordered with glass measurement rod, compression-fit glass rod adapter, lab stand with adjustable stop for quickly positioning glass rod at proper immersion depth in test sample, and temperature probe. Test method can be run either manually or using program stored in instrument memory.

Accuracy and reliability of the DVNext with Gel Timer Functionality make this instrument the preferred choice in QC for measuring gel coats, resins, and potting compounds. Viscosity data generated during the test may also prove helpful for complete characterization of material flow behavior.Packs of 10 glass rods are available; use part number GT-1010. Spare magnetic couplings can be retrofit to existing viscometers; use part number GT-2000.The DVNext instrument can also be used as a standard rotational viscometer with any standard viscometer spindle set or measurement accessory.

Each of our standard Laboratory Viscometers/ Rheometers are supplied with an internal spring used to calculate the viscosity of a material. These springs have different measuring capabilities:

1. LV is for low viscosity materials and can measure the thinnest materials. Typical examples include inks, oils, and solvents.
2. RVis for medium viscosity materials than those measured with an LV torque. Typical examples include creams, food, and paints.
3. HAis for higher viscosity materials than those measured with an RV torque. Typical examples include gels, chocolate and epoxies.
4. HBis for even higher viscosity materials than those measured with an HA torque spring. Typical examples include asphalt, caulking compounds, and molasses.
