  • Laboratory Glassware

Laboratory Glassware may be used to store the chemicals (solid or liquid), transfer of chemicals, for making solution, reagents, etc. amongst others. Most of these laboratory glassware are heat, corrosion, chemical, and temperature resistant. These laboratory glassware’s include beakers, flasks, watch glass, Petri plates measuring cylinders, test tubes etc. of various shapes and sizes to incorporate a range of volumes. They can be autoclaved and used again if sterile conditions are required. They can also be washed with soap or detergent and can be reused. Generally, a separate space is allocated for the storage of laboratory glassware in a lab. Laboratory Glassware are all well calibrated and can be easily labeled using a marker or a sticker.

Working with Laboratory Glassware

Glass is extremely durable, resistant to heat and chemicals and can be easily sterilized. Perhaps the greatest benefit, when used in scientific experiments, is its transparent qualities, as this allows experiments to be easily observed.

However, when working with glass in a laboratory setting, it’s important to consider its limitations in terms of thermal shock and mechanical stress. New staff members need to be appropriately trained in the usage and handling of laboratory glassware, and strict safety measure should be adhered to.

When creating an exothermic reaction, make sure that the experiment takes place in a suitable vessel such as an Erlenmeyer flask. It is also important to avoid warming volumetric equipment on heating plates as this can cause breakage.

Laboratory Glassware and Chemical Resistance

Laboratory Glassware is typically manufactured from borosilicate glass which is resistant to most types of acid. In fact, glass is generally highly chemical resistant but is vulnerable to alkaline substances with a 9.0 or greater PH. Alkalis attack the surface of the glass, breaking down the bonds between the silica and oxygen. The glass surface dissolves, and the overall structure of the equipment is compromised.
