Do you know an answer to a following question. What is the most common reagent you find in all kinds of laboratories types, am I correct? You got the answer right! For instance.
Water can be found in any laboratory type, be it medical, pharmaceutical, chemistry, and microbiological. These laboratories need different levels of water purity for the different levels of sensitivity of their analysis and experiments. Water Purification Process The whole water purification process is long and involves many steps. Now pay attention please. The most common purification processes used to decontaminate water of its impurities are the following.
Distillation -Water is heated and the condensed vapor is trapped and collected. So there’re still impurities found in distilled water just like silica, ammonia, and similar organic compounds. Storage of distilled water is also important to keep it from contamination. Reverse osmosis -Osmosis is the movement of water from higher concentration to lower concentration as caused by the osmotic pressure. With that said, in reverse osmosis, water is passed through a filter using a higher pressure than the osmotic pressure to separate the impurities. Of course ion exchange -This process removes various metals particularly heavy metals present in water however ion exchange will retain microorganisms. Activated carbon -known as adsorption media and works effectively removing chlorine in water by a catalytic mechanism and dissolved organics by adsorption. Now look. Ultraviolet disinfection -It uses ultraviolet light which is a powerful sterilizing agent to kill bacteria and similar microorganisms. Filtration -Filtration of water using different pore sizes ensure that other impurities which are of various sizes are also trapped and the water is uncontaminated.
These are just quite a few water purification methods used and their progressions differ from system to system as well.
There are also different kinds of water types in accordance with their use in the laboratory. This is dependent on the purification process and more importantly on the quality of water that results after the long and careful methods of purification.
Types of Laboratorygrade types Water According to the Genetic Engineering and Biotechnology News, there’re three main kinds of laboratorygrade water.
Type This is the ultrapure water which has very low levels of ions, organic molecules, bacteria, and particles.
It is commonly manufactured by combining purification technologies similar to activated carbon, reverse osmosis, ion exchange resins, ultraviolet photooxidation, filtration processes, and electrodeionization. It is used for analytical methods like ‘highpressure’ liquid chromatography, gas chromatography, and ‘inductivelycoupled’ plasma mass spectrometry. It’s very important for reagent as well as equipment preparation for molecular biology and cell culture. Type This send water type is known as pure water and may contain a minute quantity of ions, organic molecules, and possibly a small quantity of microorganisms. Known I know it’s the type which is commonly used in preparing the usual reagents and buffers inside the laboratory.
Type generated by reverse osmosis or ‘ion exchange’ this water type is used for less sensitive applications just like qualitative analyses, glassware rinsing, and water baths. Contrary to popular belief, tap water can not be used for just about anything in the lab because of the impurities found in it. Organic and inorganic compounds, microorganisms, particles, and dissolved gases are present in tap water and these impurities can affect the results of the experiments.
There are different kinds of water types corresponding to the different needs of a laboratory.
Deionized water is good for most laboratory needs but there’re certain analyses and experiments which are more sensitive and therefore, needs higher grade of lab water.
