Celloscope Automated Cell Counter
Celloscope automated cell counter was developed in the 1950s for enumeration of Red blood cell, erythrocytes, White blood cell, leukocytes, and Platelet, thrombocytes in blood samples. Together with the Coulter counter, the Celloscope analyzer can be considered one of the predecessors of today's Hematology analyzer, automated hematology analyzers, as the principle of the electrical impedance method is still utilized in cell counters installed in clinical laboratories around the world. History The Celloscope was developed for the Swedish company AB Lars Ljungberg & Co under the direction of engineer Erik Öhlin at Linson Instrument AB. In an interview published in the Clinical Biochemistry in the Nordics, a membership magazine for the Nordic Association for Clinical Chemistry, Lars Ljungberg explains that he and his coworkers had been considering different solutions for counting blood cells for some time when they came across a method presented by the American Navy on how partic ...

Red Blood Cell
Red blood cells (RBCs), referred to as erythrocytes (, with -''cyte'' translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen () to the body tissue (biology), tissues—via blood flow through the circulatory system. Erythrocytes take up oxygen in the lungs, or in fish the gills, and release it into tissues while squeezing through the body's capillary, capillaries. The cytoplasm of a red blood cell is rich in hemoglobin (Hb), an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells and the blood. Each human red blood cell contains approximately 270 million hemoglobin molecules. The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiological Cell (biology), cell function such as erythrocyte deformabil ...
