Abstract
A needle-type colloid osmometer is disclosed. This osmometer comprises a hollow needle body having at least one hole at its outer wall and acting as a part of a pressure sensing chamber, a cylindrical semipermeable membrane fitting the needle body therein, and a sampling chamber receiving the needle body with the membrane. The osmometer is usable for measuring colloid osmotic pressure of blood, lymph, body fluid or the like in the fields of clinical pathology, physiology, biochemistry, biology and the like.
