Benefits of Glass Lab Apparatus
You can use lab instruments such as conical flasks, petri-dishes, round bottom flasks, pipettes, measuring cylinders, beakers, burettes, volumetric flasks, vials, test tubes, and more that are made out of plastic or glass. Production of plastic lab equipment proceeds centuries of people using glassware lab equipment. The types of glass that are used to manufacture glass lab ware are soda-lime and borosilicate glass. Glass lab instruments have these benefits.
You may argue that glassware breaks quickly thus causing losses to the lab operators, but when you take care of them and take precautions, these lab ware items can last for a considerably long time.Stick to the thermal shock and mechanical stress of glass lab ware by adhering to safety measures to prevent them from breaking. For example, stir and cool sulphuric acid and use the appropriate vessel. Never heat volumetric instruments on heating plates for they will break.Heat glass beakers and flasks using hot plates to minimize the risk of breakage. Do not use volumetric flasks and graduated cylinders for exothermic reactions. You increase the risks of breaking your glass lab ware when you expose them to sudden temperature or pressure changes.
Glass lab ware have high clarity that enhances visibility to enable you to see, measure and recording volumes clearly and accurately. Keeping lab glassware spotlessly clean is easy because you have to maintain their visibility so that you are not obstructed when you need to measure and record the contents. You should remove the protein residues first from the apparatus using cold water. Mix a disinfectant solution at the correct dilution ratio and soak the glassware in the solution. Use a brittle brush to scrub off materials adhering to the glass gently. Use ultrasonic bath or soak the apparatus for the second time in a disinfectant solution that has been mixed at a correct dilution ratio but do not use the solution that you used earlier. Rinse the detergents from the glassware using deionized water. Dry the apparatus in a clean environment by placing them on a rack or in a hot air over to drain water from them.
They are highly compatible with common laboratory chemicals. Acids and water minimally react with glass, but the glass apparatus do not rust when they are exposed in an environment that has moisture, warmth, and oxygen. When the reaction between water or acids with glass occur, a layer of silica gel forms on the surface of the glass to prevent further reaction. However, the layer cannot form if the acid in question is hot phosphoric acid and hydrofluoric acid.
