Viscosity Mug NOVOTEST VMS

Viscosity Dip Mug NOVOTEST VMS is used to determine the convectional viscosity of the dispersion polyvinyl-acetate homopolymers coarse dispersion.


The device is a cylindrical brass vessel with a handle and three orifices, two of them are located at the lateral wall of the cylinder (by manual – lateral orifices), and the third – at the centre of the base (base orifice).


Conventional viscosity using the standard viscosity mug is to be determined at (20 ± 2) ° C. The dispersion need to be thoroughly mixed, and poured a full mug. Than lift it and watch the level of the dispersion. When the dispersion level in the viscosity mug decreases and opens the upper lateral orifice – start the stopwatch. The stopwatch is to be stopped at that moment when the dispersion comes to the level of the lower lateral orifice. The viscosity index is definite by the time (in seconds) that takes the dispersion to lower the level  from the upper lateral orifice to the lower lateral orifice. The result of the testing is the average value of three parallel testing (the discrepancy between of them should not exceed 10%).
