Why must laboratory procedures and practices be clearly communicated? By Christina Lishman INTRODUCTION: Laboratory procedures and practices are a set of guidelines which provide a clear guide on how to plan‚ perform‚ record and report all experiments safely so that human health isn’t harmed. By clearly communicating these procedures‚ it ensures quality‚ reliability and safety of the experimental activities being carried out. Laboratory procedures and practices must be clearly communicated so that

operation Laboratory rules 1) Prepare a lesson carnestly before the experiment. Clarify the related basic principle‚ sequence of the operation‚ and safety measures in the experiment. 2) Put on the working clothes before entering the laboratory. Record the experimental phenomena and data. 3) Keep the floor neat. Don’t throw anything into the water trough so as to avoid stops up. 4) After every experiment‚ the students being on duty shall take responsibility for cleaning up the laboratory‚ inspecing

The Floating Egg Problem Introduction: This experiment was constructed to aid in the practice of using the volumetric system and the glassware that determines volume. Volumetric glassware contains an accurate amount of liquid and also measures the volume accurately. Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space‚ the denser it is. Although we often confused the two‚ density and weight are actually two

accuracy of scientific glassware. I figured the smaller the glassware the more accurate the measurements would be. Which when we were preforming the experiment proved my theory. As the glassware got smaller the easier it was to get the accurate amount of water into the glassware. We went from a big flask to a small beaker to an even smaller pipette. We used a scale to get the appropriate weight of the water in the different beakers. To test this‚ we weighed multiple glassware and different sized

Role of Laboratory in Clinical Trials Laboratory data forms the backbone of all the clinical trials. Hence it is important to have good laboratory support and interaction with the laboratory in all the clinical trials. Clinical trials typically include two kinds of activity a) evaluation and validation of new clinical laboratory testing systems or b) laboratory evaluation of patients subjected to new clinical products or protocols‚ particularly those related to new drug development

Why it is important for all laboratory procedures and practices to be followed and communicated through the team. It is very important that the laboratory procedures and practices are communicated throughout the lab for the most important reason being safety. This prevents any danger and minimises risks as much as possible. For example the chemical store management minimises risks by following the correct procedures and storing the chemicals in the correct and safe places. This minimises the risks
