The use of Glass Apparatuses has been extensive in laboratories, where different types of chemicals require to be handled. Even after the introduction of plastic equipment, which are much cheaper and less breakable, Laboratory Glass Apparatuses continue to be on top of the preference lists because of their superior properties. They offer resistance to heat, have better transparency and can be easily customized. Such features make them suitable for performing multiple functions in laboratories, some of which have been discussed hereunder…
Storage: The most basic use of Lab Glassware is to store chemicals. Glass does not react with acids and bases and hence suitable for holding them. They can also be utilized for volumetric measuring if there are markings on the surface.
Heating: Reagents and samples can be heated while they are kept in Lab Glassware. Depending on the sample size and type of burner, different glassware can be selected. However, one must ensure that thermal expansion is uniform throughout the apparatus, in order to avoid fracturing.
Filtering: Specialized glass apparatuses are used for filtration of solids, liquids and gases. They are fitted with fine membranes for dispersion of gases or collection of particles. At times there are valves attached to the filters for allowing or restricting the flow.
Vacuum and Negative Pressure: Scientific Laboratory Glassware, such as, bell jars are used for vacuum and negative pressure applications, as they maintain the atmospheric pressure and also give visibility to the components inside. Make sure that the glass is not etched, cracked, chipped or scratched; else it is likely to break under the pressure.
Laboratory Glassware are very versatile in terms of their uses. However, not all apparatuses are suitable for all the processes. You must consult your Lab Glassware Supplier about the appropriateness of each equipment for different applications and also gain knowledge about their other significant features
