Many substances, because of the nature of their yield values, have been considered unsuitable for viscosity or consistency measurements with rotational viscometers. Any rotating spindle, be it cylinder, disc, or paddle, will create a channel in such substances and after a very short time exert a negligible and meaningless torque on any sensing device. This effect also occurs with materials that have a gel structure.
The Brookfield Helipath™ Stand is designed to slowly lower or raise a Brookfield Viscometer/Rheometer so that its rotating T-bar spindle will describe a helical path through the test sample. By always cutting into fresh material, the problem of channeling or separating is eliminated and meaningful viscosity/consistency measurements can be made. The automatic reversing feature of the Helipath™ Stand allows measurements to be made over a variable period of time.
Helipath Stand is coming with six T-bar spindles and 15% discount just this week!
