  • Ideal for routine plant quality control checks and research laboratory applications
This viscometer is extremely easy to use; first fill the tube with sample, then invert tube. Next, restore tube to nornal position, turn the knob to release the ball, and then simply measure the time of descent. The ball moves against a white background with red reference lines making it easy to read. Repeatability with good technique varies from ±0.2 to ±1.0%, depending upon time of descent. Viscometers require a 7-mL sample volume.
Viscometers have wetted materials of glass, Viton®, and Delrin® acetal. PTFE O-rings are available for use with lquids that adhere to Viton®; call our Applications Specialists for more information.
What's Included:
one glass and one 316 stainless steel (SS) high-precision ball. For higher viscosity ranges, use the optional tantalum ball (sold separately).
Hot Tips:
NT falling ball viscometers conform to ASTM D 1343-93.
Product Type Falling Ball Viscometer
Range 0.2 to 2 cp (glass ball)
1 to 10 cp (SS ball)
2 to 20 cp (optional tantalum ball)
Model GV-2100

  • Q:

    I haba been trying to measure the glycerin viscosity with this viscosimeter. The problem is when I put the ball in the tube, it has not been downing (just stop)..what could be the problem?
    Asked on 5/13/2013 by Antonio from Canadá

      A:

      Pure glycerin is approximately 1400 centipoise at standard temperatures, and this meter will only measure products up to 10 centipoise. Part number: 08702-10 is a more appropriate falling ball viscometer for such a viscous liquid, and will measure up to 2000 centipoise with the tantalum ball.

      A:

      Hot water or some compatible solvent that would remove the fluid that is causing it to stick perhaps? Please call for additional assistance.

  • Q:

    I cannot get the glass ball to stay in the ball release device. I have tightened all the way and loosened all the way. Is there a technique that I am missing or has the O-ring gone bad?
    Thanks

  • Q:

    Some time ago I purchased two viscometers and now I cannot find the pages with time versus viscosity that came with them. Are those sheets available for the medium and high-viscosity ball viscometers?

    thanks

      Comments about Gilmont<reg> Fallng Ball Viscometer, 0.2 to 2 / 1 to 10 centipoise:

      Provides an economical way to measure viscosity, a manual process requires accurate time keeping (the rate of ball drop between two measured points). Ambient temperature must be controlled and accurate vertical set up is critical for accurate, repeatable results.
      Our R&D department has found this to be a fast and easy to use method to measure viscosity of the protein solution development. Because it is manual, I do not consider it to be a precision quanitative or qualitative instrument, but it is a great value for feedback in your process development.

      We were not able to complete a single viscosity test with this instrument. I would recommend a Cannon viscometer instead.

      Comments about Gilmont<reg> Fallng Ball Viscometer, 0.2 to 2 / 1 to 10 centipoise:

      The knobs were difficult to use to drop the ball, and when I tried measruing the viscosity of water at room temperature it gave me 2 cp! I followed the instruction exactly, even building a tabletop just to make sure its perpendicular to the ground and that there's no micro-air bubbles or spinning of the ball.

      It is more accurate than rotating one. Rotating one is really not good compared to this (Brookfield) I guess I catch easily 0.2 centipose repeatability with this. They say you can do more.
