This is a specialized accessory for lab work: Rotor No. 0 for certain models of rotary viscometers, like the DHJ-5S or DHJ-8S. If you work in a lab measuring the thickness (viscosity) of liquids, you know different samples need different tools. The standard rotors (No. 1-4) that come with many viscometers are great for a wide range, but Rotor No. 0 is specially designed for one thing: measuring very LOW viscosity samples. We're talking about thin fluids like some solvents, light oils, or diluted solutions, with measurements potentially down to 0.1 mPa.s. It has a cylindrical shape which allows for a more precise calculation of the shear rate during testing – this gives you better, more detailed data for your product analysis reports. Another advantage is it only needs a small sample volume, about 25 ml, which is great when you don't have a lot of material to spare. If you're using a compatible rotary viscometer and often find yourself testing thin liquids where your standard rotor isn't sensitive enough, adding this Rotor No. 0 to your lab expands your machine's capabilities. It's a precision-made part that ensures accurate, repeatable results for quality control, R&D, or formulation work in industries like cosmetics, paints, chemicals, or pharmaceuticals. Always check that this rotor number is compatible with your specific viscometer model before purchasing.
