Zahn Cup Immersion Viscosity Cup No.1/2/3/4/5 Stainless Steel 44ml for Test The Viscosity of Newtonian or Approximate Newtonian Liquid (NO.5)

• 【Core Specs & ASTM Compliance】: This Zahn cup has a 44ml volume and comes in 5 precise specifications (#1 to #5), complying with ASTM D 4212 (Standard Test Method for Viscosity Cup Immersion). Crafted from stainless steel with CNC precision-drilled orifices and molded bodies, it ensures accurate viscosity testing.
• 【Wide Fluid Applicability & Size Selection】: Ideal for quickly measuring viscosity of Newtonian/similar fluids—including paint, ink, varnishes, syrup, and oil. Choose cup sizes by viscosity: use large-number cups (e.g., #4-#5) for high viscosity, small-number cups (e.g., #1-#2) for low viscosity.
• 【Precision Measurement】: Viscosity is expressed in Zahn seconds. The high-speed CNC-drilled orifices and precisely molded stainless steel construction guarantee consistent, reliable test results every time.
• 【Practical Product Protection】: Designed to maintain product viscosity stability during use, keeping it within the set range. This ensures the product’s color and performance remain consistent.
• 【Worry-free After-sales Service】: Buy with peace of mind. If you’re unsatisfied for any reason, you can contact us for after-sales service. We stand behind every Zahn cup, ensuring you order with confidence.

Description: The immersion viscosity cup, also known as the Zahn Cup. The viscosity cup is used to test the viscosity of Newtonian or approximately Newtonian liquids. Scope of Application： 1 #: apply very thin liquid 2 #: thin oil, mixed paint, varnish 3 #: medium viscosity, mixed paint, varnish 4 #: thicker fluids and mixtures 5 #: particularly viscous fluids and mixtures Specifications Cup material: stainless steel Weight:136g Dimensions: 380 × 70 × 80mm (length × width × height) Package Included: 1* Zahn Cup  Use and maintenance: 1. Before and after use, the appropriate cosmetic agent was cleaned 2. Select the appropriate cup number to control the elapsed time between 20 and 80 seconds. See Table 1 with a variety of cups to apply the viscosity range. 3. The cup body is immersed in the container for 1-5 minutes. Then, the cup body achieves heat balance, and the cup is lifted vertically. The action should be fast and smooth. From the upper end of the cup, from the liquid surface, from the time. Liquid outflow should be kept in the vertical body, and the liquid surface distance should not be more than 150MM. When the first breakpoint to stop the time is reached, then the flow of time in seconds is determined for a certain size of viscosity value. The difference between the two measured values should be less than 5% of the average.
