[Direct method for osmotic pressure measurement (author's transl)].
A new dynamic method to measure osmotic pressure was presented. The method is easy and with only a 1.8% degree of error. All determinations were done with an osmometer, equipped with three small chambers of methyl metacrilate and dialyser membranes. The central area had two capillaries: one for measuring and the other for changing dynamic pressure. The data from different albumin concentrations were satisfactory, and they agreed with published results from others. The present results indicate that osmotic pressure is an exponential function of albumin concentration.
