The 40 Standard Rod has the sturdiness suitable for the majority of general laboratory applications. Made entirely of steel, it has a 1.5 in. diameter and is 14.0 in. tall. Steel provides much greater dynamic rigidity than aluminum due to its almost order-of-magnitude greater material loss factor. This means the 40 rod has a high resonant frequency and correspondingly low vibration amplitude required for optical laboratory use. Also, with its inherently greater stiffness and strength, it supports larger loads with greater stability. Steel construction has other advantages such as steel has half the thermal expansion coefficient of aluminum and a higher heat capacity so thermal stability is enhanced. 1/4-20 thread.
