A bioreactor can define as a controlled Vessel where biological’ process are carried out for growing cells, microorganism’s, or enzymes, and It is considered an essential component of many Industrial Biotechnology fields . Definition of Bioreactor A bioreactor is a device or system used to cultivate and grow biological cells, tissues, … Read more
What are Microscopes? A microscope can define as an optical or electronic Instrument that is used for observing objects’ that are too small for the naked eye, and it gives a look into structures in biology/physics etc. In general terms, the device is characterized by lenses, illumination sources, and also by Magnification system’s that allow … Read more
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 Native Polyacrylamide Gel Electrophoresis? Native Polyacrylamide Gel Electrophoresis (often written as Native PAGE) can be defined as a technique where proteins’ mixtures are separated under non-denaturing condition’s, so their natural Shape and Charge are mostly preserved. In this method the protein’s are moved through a polyacrylamide matrix (PAM) by an electric field,and their … 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.
