BIOL 1208 Chapter : Cell Hemolysis Lab Report
Document Summary
Title: the effect of hemolysis in different types of glycols. In this experiment, the effect of hemolysis time was measured in three different glycols. Hemolysis is the bursting of red blood cells caused by water crossing the cell membrane. Red blood cells were placed in solutions of varying molecular weight (ethylene, diethylene, and triethylene glycols). As the blood was added to the test solutions, the hemolysis process began. Hemolysis occurred after the solution was clear and the black thread could be seen through the solution using the silt lamp. Ethylene glycol lysed cells faster at a mean of 15. 93 +/- . 417 seconds and triethylene glycol lysed the slowest at a mean of 26. 7 +/- 1. 731 seconds. Therefore, the longer it took for hemolysis to occur, the heavier the glycol was. Osmosis is the net movement of water across a cell membrane from an area of low concentration to an area of high concentration.
