Abstract
Abstract A stand for instruments of metal for use in the field of medicine, particularly odontology, comprising a body composed of a large number of sheets of a liquid impregnatable paper material. The sheets are arranged vertically close together so that the instruments are insertable by their operating ends between the sheets to be retained there during the sterilizing process and are thus stored easily accessible for subsequent clinical work. The sheets of paper are impregnated with a corrosion inhibitor to protect the instruments at least during a sterilizing process.
