Apparatus for measuring coloidosmotic pressures (Machine-translation by Google Translate, not legally binding)

摘要

Apparatus for measuring colloid osmotic pressures, characterized in that it comprises a calibration assembly, a dosing and sample washing assembly, and a colloid osmotic pressure measurement assembly, the calibration set consisting of a compressor device and a column pressure meter of mercury, both interconnected with each other and with the dosing and sample washing assembly, whose dosing and washing assembly comprises in turn a chamber from which three conduits depart, provided with the corresponding stopcocks, one for intercommunication with the calibration set another that flows into the atmosphere and the third that leads to a collection tank of washing liquid, whose tank is in turn in communication with a suction device, with the interposition of an aspiration meter, also communicating said chamber with another camera belonging to the measurement set, filled with a liquid isotope the measuring assembly further comprises a pressure translator which is connected to an electronic amplifier and this in turn to a recorder, the dosing chamber and the pressure meter chamber being separated by a semi-permeable membrane, below the which, inside the measuring chamber, there is disposed a device for supporting said membrane, whose device defines one or more capillary passages between the lower face of the membrane and the bottom of said measuring chamber, from whose bottom part a conduit through which the pressure existing below the semipermeable membrane acts on the pressure translator.
