Zahn viscosity flow cups.

The ez viscosity cup series is a logical and necessary outgrowth of the standardization studies on the zahn signature and similar cups for the promotion of this most popular type of viscosity measuring instrument as a national and international standard. Vtsyiqi 1 zahn cup stainless steel zhan viscosity cup with 1 zahn cup viscosity cup viscometer flow cup 1 brand new 44ml cup volume white. Viscosity is determined by the time required for a definite volume of liquid to flow through the orifice. Free shipping by amazon.

The zahn viscosimeter is a bullet shaped corrosion resistant stainless steel cup with a precision drilled orifice. The zahn cup s reading could be less sensitive than an automated viscometer employing a higher shear methodology. Also known as zahn cups these testers let you calculate viscosity based on the speed at which a liquid drains through a cup with a hole at the bottom. Use the included formula to convert seconds.

The size of the hole is in mm and a zahn 4 means a zahn cup with a 4mm hole. The only forces at work are gravity causing the flow and the hole size and gauge of the cup. To determine viscosity dip the cup in a liquid until it is completely filled lift the cup out of the liquid and time how many seconds it takes for the liquid to drain out of the hole in the bottom. Different cups have different shapes and hole sizes and because times too short or too long are unsuitable for any given viscosity there is an optimum cup with times in the 15 60s range.
