Pros of Glass Lab Instruments

Glass and plastic are used to make essential lab apparatus like conical flasks, petri-dishes, round bottom flasks, pipettes, measuring cylinders, beakers, burettes, volumetric flasks, vials, test tubes, and more. Glass lab ware has been in existence longer than plastic ones. The types of glass that are used to manufacture glass lab ware are soda-lime and borosilicate glass. Here are the advantages of lab glass apparatus.

You should take precautions when using glassware in the lab to protect them from breaking so that they can last longer. Understand the thermal shock and mechanical stress of glass lab ware and take precautions not to go beyond that by sticking to safety measures to protect them from breaking. A great example is to use the right vessel for sulphuric acid reaction by ensuring that you stir and cool that acid before using it for any experiment. Heating volumetric instruments on heating plates increase their risks of breaking.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. Glass instruments cannot withstand sudden temperature or pressure changes because that makes them break.

You can see, measure and recording volumes accurately and clearly from glass lab ware because they have high clarity that enhances visibility. Cleaning lab glass instruments is easy so that they remain visible for you to measure and record liquids and solids accurately. Clean the glassware in cold water to remove protein residues. Soak the apparatus in a disinfectant solution that has been mixed at a correct dilution ratio. A brittle brush should be used to 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. Use deionized water to rinse detergents off the lab glassware. 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. You can use or store them in environments that have moisture, warmth, and oxygen because glass is not susceptible to rusting and they also react minimally with water and acids. 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. When the reaction is between hot phosphoric acid and hydrofluoric acid and glass the layer will not form.
