A centrifuge can define as a laboratory device that use rapid rotational Force to separate component’s of a mixture based on their Density difference’s, and it is considered a key Instrumentation in many biological / chemical workflows. What is Relative Centrifugal Force (RCF)? Relative Centrifugal Force (RCF) is the effective acceleration a particle experiences in … Read more
What is Lane-Eynon Method? Principle of Lane-Eynon Method The method based on reduction of cupric ions (Cu²⁺) to cuprous oxide (Cu₂O) by the reducing sugars in alkaline condition. In the reaction, CuSO₄ from Fehling A and alkaline tartrate from Fehling B react to form a deep blue cupric–tartrate complex, which remain stable in hot solution … Read more
Microorganisms are everywhere in their the distribution. In any given environment, many microorganisms are present at any given time. It is difficult to identify a specific kind of microbe until we understand their ecological needs. For instance, anaerobic microbes do not require oxygen those that are aerobic require oxygen micro-aerophiles to have oxygen however, in a small amount. So, we require cotton plugs to provide an conditions that are aerobic and keep the growing culture uninvolved with unwanted microbes. Cotton plugs are made of cotton along with air pours. Air can flow through air pours, but not the bacteria that cause microbial contamination. They are fixed to the surface of cotton fibres , and prevent them from being able from getting into flasks, tubes, etc. Air aids in for the development of microorganisms within glass equipment.
