Chemistry is all about different chemicals. These chemicals are divided basically into acids and bases, both of which if come in contact with the human body, create problems. Acids lead to burns and deteoration of the human skin whereas bases can cause blisters and give the skin an unhealthy look. To prevent such accidents and keep these chemicals well contained different laboratory instruments are used. But what makes these instruments contain the harsh and dangerous chemicals? The answer to this question is the glassware used to make these instruments. Also known as scientific glassware, it is prepared according to the needs of the chemicals and is pretty strong in the case of containing high power acids.
Different types of scientific glassware are mentioned below, along with a little description related to each of them.
Flask- The most commonly used glassware, it is used to store different liquids in the laboratory. It comes in different sizes and shapes. Round bottom flasks and volumetric flasks are most common among them.
Burettes- These are long tube like structure which have readings marked on them to measure the liquid. These are basically used to measure the liquids and give accurate results. They come with separate metal holder to support the tube without direct contact, in case it is heated up.
Beakers- These are also containers and quite similar to a flask. But the major difference is that while the flask is conical in shape these beakers are cylindrical in shape which leads to easier access due to an open mouth.
Test Tubes- These are small cylindrical structures in the form of tubes. These are mainly used for mixing small amount of chemicals and can also be used for temporary storage. Also serve a numerous amount of purposes such as can be kept in plants in sunlight.Scientific Glass Services
Bottles- The very common glassware, these bottles are used in the case of long term storage and have a lid to cover up the liquid hence preventing the escape of harmful and toxic gases into the environment.
The above mentioned instruments can be made up of any type of glass material but their primary function is always the same, to handle the chemicals and the scientific glassware remains same as divided into the types above and its material does not really make a difference to its types.
But there are a number of factors which need to be kept in mind before selecting the right type of scientific glassware. It should provide maximum resistance to thermal shock and should have high chemical potency as well as survival at high temperatures. A thin and standardised wall of the glassware lasts longer. Lower is the alkalinity of the scientific glassware ; longer is the life of the glassware. Rather than going for cheap alternatives, go for products which have been standardised and approved by the industrial certifications. The properties of transparency, shock resistance, almost no reaction to the chemical substances and being easily washed off make glassware perfect for daily use in laboratories.
