Laboratory Glassware…To Be Handled With Care
means the varied apparatus made of glass which is used for experiments and work in science. It is an important feature of scientific laboratories where quality considerations are very high. The demand for laboratory glassware arises from its qualities of withstanding high temperatures, high pressures, chemical attacks and blocking infrared and ultraviolet radiation.
How Is Laboratory Glassware Produced?
Normally, laboratory glassware is bulk-produced; however, specific apparatus is custom-made through glass blowing. Scientific glass blowing is a specialized field wherein several glass parts are fused together with great precision to get the required shapes and dimensions. The skill of the glass blower becomes very crucial in satisfying the requirement of high precision. Special reaction flasks, vacuum manifolds are some of the specialized items made through glass blowing.
Varieties of Laboratory Glassware & Its Uses
Some of the commonly observed glassware in laboratories and their uses are detailed below:
Beakers, flasks, bottles, vials are containers in different shapes and sizes which are used to store or hold samples or reagents. Jars are other cylindrical sealed mediums which act as containers and the Bell jar variety is used to hold vacuums.
For precision in volumes, Graduated cylinders, Burettes and glass pipettes are used.
Flat glassware includes Watch glasses, glass petri dishes and glass evaporating dishes which are used as surface covers, to culture living cells and evaporating materials respectively.
Some other items are glass retorts used for distillation purpose, stirring rods for mixing chemicals, drying pistols for eliminating water or impurity content from samples and microscopic slides.
How Do You Clean Laboratory Glassware?
Various cleaning solutions made from chromium-free and phosphate-free formulations are available in the market. The instructions given for its use should be closely followed. These are obtained from any of the suppliers or dealers in laboratory glassware equipment.
