An automated osmometer.
A freezing-point apparatus, which measures osmotic pressure by determining freezingpoint depression, was modified by incorporating a slowly rotating circular tray with space for 30 sample vials, and a sample pick-up device. The instrument is designed to automatically pick up a cuvet containing a 2-mi. specimen of serum, urine, spinal fluid, or any biologic fluid, and to cool, supercool, freeze,...
متن کاملA Convenient Small Osmometer
A description is given of a simple, rugged instrument for determining the osmotic pressure developed by a solution of a high polymer. Other small osmometers described previously [1, 2, 3, 4, 5]/ have been, in some respects, too inconvenient to use. Although relatively easy to make, glass osmometers are fragile and may require frequent repairs. Small metal osmometers, in addition to being rugged...
متن کاملThe Erythrocyte Ghost Is a Perfect Osmometer
The osmotic swelling of intact erythrocytes in hypotonic solutions was measured using microhematocrit tubes, Van Allen tubes, and a calibrated Coulter counter. In agreement with earlier workers the intact cells did not behave as perfect osmometers, the cells swelling less than predicted by the Boyle-van't Hoff law. Erythrocyte ghosts were prepared from fresh intact erythrocytes by one-step hemo...
متن کاملA sensitive and accurate gel osmometer.
1. A bilayer strip, cut from a thin layer of cross-linked polyacrylamide gel cast on to cellulose tissue, forms an open circular loop whose ends are close together. Shrinkage of the gel, in response to the osmotic pressure of a non-penetrating solution, causes a proportional separation of the ends of the loop. This is measured with a microscope and micrometer eyepiece. 2. The resulting effectiv...
متن کاملLutetium-177 DOTATATE Production with an Automated Radiopharmaceutical Synthesis System
Objective(s): Peptide Receptor Radionuclide Therapy (PRRT) with yttrium-90 (90Y) and lutetium-177 (177Lu)-labelled SST analogues are now therapy option for patients who have failed to respond to conventional medical therapy. In-house production with automated PRRT synthesis systems have clear advantages over manual methods resulting in increasing use in hospital-based radiopharmacies. We report...
