Abstract
A method of sealing a cryogenic tube comprising the steps of inserting the tube into a tubular body made from a heat-shrinkable material and having a length greater than that of the receptacle, heating the tubular body to a temperature sufficiently high to effect shrinkage of the tubular body and compressing the ends of the tubular body to cause the opposite tube walls to melt together to form an envelope completely surrounding the receptacle.
