The patent relates to a device for use with standard tensile testing machines for conducting low temperature measurements, such as, yield strength, tensile strength, modulus of elasticity, ductility, stress-strain relation and shear strength. One object of this invention is to provide a cryostat for use with standard tensile testing machines which is capable of obtaining any temperature in a range from between 4 and 300 Kelvin, without the use of an external heat exchanger.
