From the ancient times till today, chemical research teams have used glass containers for a very basic reason which is the transparency of glass which actually appears almost invisible. And so the contents and the reaction are clearly visible. But because chemists must heat, cool and mix chemical substances, ordinary glass is not always adequate to be employed as laboratory glassware. Laboratory work requires apparatus made with glass which can readily be moulded into any desired shape or form, which offers maximum inertness when in contact with the widest range of chemical substances, which can withstand thermal shock without fracture and high temperature work without deforming, and which will be resilient enough to survive the everyday knocks to which it will be subjected in normal laboratory handling, washing and sterilizing processes. Glass items represent optimum mechanical, thermal and chemical behaviour. This glass is used in laboratory glassware as well as for industrial applications where maximum thermal resistance, thermal shock resistance, mechanical resistance as well as unusual chemical resistance are required.
Lab Hot Air Oven is commonly used for dry heat sterilization. Dry heat sterilization is a method of controlling microorganisms.The working principle is based on fine gravity air convection in an electrically heated chamber. The machine is equipped with various components to ensure the uniform heating throughout the chamber. Two jacket design, automatic control unit, PID controlled, PT 100 sensors, temperature preset, etc. allows the machine to work efficiently and return to normal temperature when the test process is over. It is designed to simplify the process of dry sterilisation and pre-treatment of different materials like rubber, plastic, etc.
Inside the chamber of hot air oven, the air flows in a forced circulation manner, this allows the appropriate heat distribution inside the chamber. As the air inside the chamber becomes hot, it becomes lighter and moves in the upward direction. As it reaches the top, the fan inside the chamber pushes it back to the bottom.It employs higher temperatures in the range of 160-180°C and requires exposures time up to 2 hour, depending upon the temperature employed. This creates a circular motion inside the cabinet and makes a consistent circular flow of the air. With this process, eventually, the optimum temperature is achieved.The benefit of dry heat includes good penetrability and non-corrosive nature which makes it applicable for sterilizing glasswares and metal surgical instruments.
It is always to be taken care that articles kept for sterilisation should not be taken out immediately.
Dry heat in a lab muffle furnace also destroys bacterial endotoxins (or pyrogens) which are difficult to eliminate by other means and this property makes it applicable for sterilizing glass bottles which are to be filled aseptically). Dry heat kills by Oxidation, Protein Denaturation and toxic effects of eleveated levels of electrolytes.Let the oven comes to a normal temperature and then the articles are taken out.

The story behind the subject dates back to the IT boom and service sector industry revolution in the late 90’s. India became the second largest exporter of IT related products on the global platform. Now with this IT revolution came the need for IT talent and skill oriented manpower. The scarcity of skilled manpower coinciding with the boom in the industry led to massive pay packages for the IT skilled man power.
Getting an IT job in a multinational company became the dream of majority of youngsters and their parents in India. Suddenly IT became the most sought after engineering course in the country. Even If one could not make it to the computer science & engineering branch at the graduation level they dreamt of doing their masters in CSE. Everyone wanted to join an IT company irrespective of the branch of engineering they completed their bachelors in.
This led to a huge demand for IT oriented courses in the country which paved the foundation of mushrooming engineering colleges in the country. But there was a limitation to the number of seats in CSE branch as the intake had to be at par with the intake in any other engineering course branch as per the policy made by council of technical education. So here colleges created a shadow branch of Computer Science Engineering which is known Information and Technology Engineering.
IT is just a reflection of computer science & engineering just to fill the gap in supply and demand for the skilled manpower in the IT sector. Hence it can be said that theoretically there is no difference in both the branches, the mere reason of creating the two is to provide a larger number of pass outs with the same skill set by staying in the limitations of bureaucratic guidleines.
Numerous courses have evolved for science education students other than the traditional courses of medicine and engineering offering a wide platter of degree and diploma courses. If communication and creativity is your forte then colleges are offering various courses ranging from mass media to journalism. These courses include bachelors and diploma program in journalism, mass communication, advertising, digital media. Completion of these courses leads to well established careers in the respective fields.
There has been a very old notion that technical education is necessary to future development and innovation. This is a major reason why all developed and developing economies across the globe have technical educational institutions as part of their social infrastructure.
Hot air oven is an electrically heated test device that are basically used in sterilization. The Hot Air Ovens use dry heat to sterilize articles. These are known to work by circulating hot air inside the test chamber to achieve maximum and uniform heat distribution around all corners of the oven . These types of hot air ovens do not require water and there is not much pressure build up within the oven that makes them more suitable to be used in a laboratory environment.
