Viscosity Bath Manufactures in Ahmedabad Brand: Hema Typically, a viscosity bath consists of a tank filled with a heat-conducting medium, such as water or oil, which can be precisely heated or cooled. The sample liquid is placed in a container or tube that is submerged in the bath. Temperature sensors ensure the bath maintains the desired range, preventing overheating or underheating. This setup ensures that the sample liquid is tested at the correct and uniform temperature required for viscosity testing. Temperature-controlled baths are essential for processes that require stringent control over physical properties.
