Laboratory Glassware – Applications, Safe Handling And Cleaning-jkforum

Business What is Laboratory Glassware? Laboratory Glassware refers to the scientific instruments mainly made of glass. These Instruments are transparent, inert and more heat resistant than plastic. Various types of glass are used in manufacturing laboratory equipment like test tubes, reaction flasks, beakers, storage flasks and many others. For instance, boro-silicate glass is used in reagent bottles as it is less susceptible to thermal stress. Also, quartz glass is commonly used in manufacturing certain parts of electromagnetic spectrum as it possess high transparency and can withstand high temperatures. Further, Heavy wall glass is used for pressure reactor in high pressurized reactions. When in use, this glassware is held by clamps in place and initiate reactions. Application of Laboratory Glassware These glass wares are used for variety of purpose like volumetric measuring, storing strong chemicals or samples, mixing solutions and others. Laboratory glassware is commonly used to make clear and accurate observations. Various other processes in which such glassware is required include chemical reactions, heating, cooling, distillation, chromatography, spectrography, pressure reactors and others. Safe handling of Laboratory Glassware Equipment made of glass are fragile and have a tendency to break under various conditions. Hence, while working with these type of equipment, user needs to know the proper handling of such glassware. Also, it is necessary to know the compatibility between various chemicals and the glasses used to hold the chemical. For example, hydrofluoric acid is stored in polyethylene containers as it reacts with glass. Also, not every instrument can be used for all purpose. For instance, Round-bottom flasks are best used for boiling liquids. Test tubes need to be held firmly with hands or clamps to avoid breakage and accidents. It is required that the user wears proper laboratory gear like gloves and coats for proper handling in order to avoid accidents. Gloves in general, help in minimizing or eliminating the chances of skin coming in contact with various harmful chemicals. Insulated gloves must be used while working with extreme temperatures. Cleaning Laboratory Glassware It is a very tedious task to clean the thin test tubes and conical flasks. All glass wares need to be thoroughly washed after use. Cleaning process usually starts by dissolving the glassware into a cleaning solution. This helps in removing grease and loosening most of the contamination. Further, scrubbing with brush can help in removing the dirt and impurities left in tube. Acetone is often used for sensitive and final wash of urgently needed glassware. Then, the Glassware is dried using a hot air fan which blows it dry. The alternative method is to place the glassware under vacuum. Other cleaning reagents used for cleaning glassware are aqua regia, pirahna solution and chromic acid. Chromic acid is not advisable if the glassware is to be used for biological sciences. Moreover, Ultrasonic cleaners have been able to provide laboratories with versatility in cleaning. These provide lab technicians with the facility of cleaning efficiently as well as quickly. Therefore, saving man-hours is one of the main benefits of these cleaners. About the Author: 相关的主题文章:
