我们已经开发了一个简单的系统，用于在10（-3）至10（1）Pa. s范围内测量粘度。在旋转的外部磁场下，铝球在样品池中旋转，球体的旋转速度给出样品粘度。低粘度可以通过使用微探针球体来测量，因为施加到球体的粘性扭矩克服了在足够小的球体半径处的摩擦力。该系统无污染，可以很容易地应用于医学和生物学研究。(C)2010日本应用物理学会
We have developed a simple system for viscosity measurement in the range of 10(-3) to 10(1) Pa.s. An aluminum sphere revolves in a sample cell under a rotating external magnetic field, and the rotational speed of the sphere gives the sample viscosity. Low viscosities can be measured by using a micro-probe sphere, since the viscous torque applied to the sphere overcomes the frictional force at a sufficiently small sphere radius. The system is free from contamination and can be easily applied to medical and biological studies. (C) 2010 The Japan Society of Applied Physics
