Alternative to Gardner Tube Viscosity Measurement

[Lue]

I am currently using garder tubes to measure the viscosity of a material (mainly adhesives and some wax) in the process of manufacturing Newtonian as well as non-Newtonian materials. I am looking for an alternative method that is less qualatative in an attempt to decrease the defects per million opportunities as well as capture the data in some sort of software. The cone and plate viscometers have been researched and don't work well for us due to a very fine film that accumulates over a small amount of time. I am looking into a m-vroc by RheoSense does anyone have any experience with this? Do you have an alternative?

I have used the RheoSense m-VROC for viscosity measurements of non-Newtonian materials and it is a reliable system. It is easy to use, and the data is captured in a software package that can be used to analyse the results. You may also want to consider using a rotational rheometer which provides more detailed information about the viscoelastic properties of the material than the m-VROC. However, the cost of these systems is significantly higher than the m-VROC. Another option is to use a falling ball viscometer, which is a low-cost alternative to the m-VROC and can provide accurate viscosity measurements of non-Newtonian materials.
