Chemistry Glassware: Delicacy means

Each type of chemistry glassware has different functions and properties. It should be resistant to chemical attack, withstand sterilization, and need to measure specific volume, need to resist extreme temperature. It includes beakers, boiling flasks, burettes, funnels, pipettes, conical flasks, cylindrical flasks etc. To resist glass from breaking chemical need to be cool down or should be heated. So mostly they are made out of borosilicate such as Pyrex or Kimax which are more durable compared to ordinary glass. All chemistry glassware should be cleaned immediately after the usage.

The chemistryglassware is mainly used in laboratories and chemical companies. The peculiar characteristics required by these professionals are its transparency and heat and cold resistance. If you utilize it in specified manner it is easy to handle and maintain. Glassware are used in lab due to its utility in processes like mixing, separation, extraction, filtration etc. It is also not a good idea to dry the glassware using cotton cloth or other fabric because this may bring impurities and fibers and may destroy the chemical solution. It is better to leave it to dry by itself. If there is no time and you need to use it immediately it is a better to rinse two or three times with acetone. This will remove water and help to evaporate immediately. All glassware should be grease free because this will not help the glassware to be uniformly cleaned .When you are using or cleaning it; it is always advisable to wear gloves and eye protectors.

Three-way Stop Cock – Important apparatus for laboratories

Would you ever believe that a valve with three outlets allow the fluids to flow out of only a single outlet? Yes it is true and such an apparatus is known as three-way stopcock.

A stopcock is a valve used to control the flow of liquid or gases through a tube; it is also used to prevent excess water flow in a domestic water system. Such stopcocks are prepared from glass and rubber. Formation of a three-way stopcock is just similar to an ordinary tap. In a three-way stopcock, the cock is sensitive to direction of flow. It is made in such a way that there is a main tube with a small hole which is attached to another three different tubes arranged perpendicularly to each other. The main tube can be rotated in all the directions, which allows the fluid to pass out through different outlets in required amount. Such three-way stopcock is mainly used in laboratories and domestic water supply. Three-way stopcock is very much useful to mix the correct substance with other substance in properly required amount. But it is of utmost importance that you should know how to use it in a laboratory to get the desired results because a little negligence can alter the result of the experiments.

Such stop cocks have multiple uses as mentioned above. Besides, three-way stopcock also helps the work to be completed in less time. While using Three-way stopcock, no extra care is required and it can be easily transferred to other places as well.

Soxhlet apparatus: Extracting the insoluble impurity

Have you ever been to a scientific laboratory and seen the exotic equipment in the laboratories looking like the articles of embellishments? If you are not a person dealing with the science or scientific experiments, the talk matters little to you. But for a scientist or a person dealing with scientific laboratory would respect the value they have in bringing about astounding miracles in the field of science and technology. Soxhlet apparatus is equipment in the scientific laboratory that is used to extract the insoluble impurity from the solvents. It was invented in 1879 by Franz Von Soxhlet and the name soxhlet apparatus honors the inventor. Originally it was designed to extract lipids from solid material but with the passage to time its use has taken different dimensions.

Soxhlet apparatus made of glass material and is a combination of thimble made from filter paper, flask, chamber, condenser etc and through the support of heating it makes the distillation process possible. When a desired compound has a limited solubility in a solvent the soxhlet apparatus is used. By heating the solvent it is vaporized which travels up a distillation arm and moves into the chamber and through the use of condenser it is condensed here.

Soxhlet apparatus is used for a particular purpose and therefore its use in the laboratory is not as frequent as the other equipment like test tubes, pipettes etc. But no equipment can replace its use and as it is the combination of different parts it needs to be handled with care.
