Types and Scientific Use of Laboratory Glassware
Glass containers or beakers are common Laboratory Glassware which is available in various forms. These are used for heating chemicals or for transporting and mixing different types of fluids during experiments. Most of these beakers are graduated and can be classified as boiling tubes, thistle tubes, test tubes, NMR tube and centrifuge tubes.
Volumetric flask has oval base and long narrow neck with glass or PTFE stopper and these are used for preparing of various standard solutions. Pipets are used for drawing specific amount of sample during any experiment. Some of these pipets are graduated and have squeeze bulbs attached to one end. Funnels, burettes, pipettes and graduated cylinders are also used for performing various types of experiments and are considered as commonly used glassware.
Manufacturers use quality raw materials and modern tools for manufacturing these glass products. Borosilicate glass and clear plastic are some of the most commonly used raw materials which give rigidity and durability to these products. The manufacturers carefully select these raw materials and check each and every step during the manufacturing process. They remove the broken test tubes and flasks and reuse them to manufacture new products and through this way they reduce the cost of production. Most of these manufacturers supply these glass items to various scientific institutions and research Center.
One can purchase this glassware directly from the distributors and manufacturers. One can even ask them to alter the shape and the size of these glass items as per their requirement. There are various online stores from where one can buy these items at a discounted price.
One should always take care of these glass items in order to use them for various types of experiment and also for a longer period of time. To remove the stains and grease one should soak these items in detergent solution. One can use brushes and scrubbers to remove heavy stains and particles. Hydrofluoric acid, chromic acid and aqua regia are used to clean these glass products. One should avoid the usage of the harsh chemicals and cleaning agents to keep these items in a perfect state. After cleaning, these beakers, test tubes and funnels should be dried and then used.
