Why heat the inoculating loop after each transfer of microorganisms?
Wiki User
∙ 14y ago
It is necessary to heat the inoculating loop after each transfer in order not to cross contaminate the media you are working with. It is also needed to maintain universal sterile procedures in a laboratory environment.

What is an inoculation?
Inoculating needle is used like a pen. Hold it like you hold a pen. Inoculating loop and a needle is mainly used to pick a single colony(pure) so u need to be gentle on the agar. practice using an inoculating needle on a paper with pen.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
Which type of heat transfer is by direct contract?
The type of heat transfer by direct contact is called conduction. Heat is transferred through a solid material or between two objects in direct contact with each other. This occurs as the particles in the material or objects collide and transfer energy to each other.
Why would you not use heat to kill microorganisms in a protein-rich solution?
You certainly can use heat to kill microorganisms in a "protein-rich" solution if you don't care whether the proteins get denatured or not.
What is the methods of heat transfer?
Heat can be transferred in 3 ways: Conduction, or through direct contact, Convection, or transfer of heat through a fluid, or Radiation, or heat transfer through space in the form of electromagnetic waves.
What is the problem for heat cold and microorganisms?
what is the promble for heat, cold microorganisms
Why should you let the inoculating loop cool first before and after using it?
The inoculating tube is cooled before use so that the organism is not killed by extensive heat.

What do conduction convection and radiation mean?
conduction is the transfer of heat between two surfaces in contact with each other convection is the transfer of heat into a moving fluid radiation is the transfer of heat via electromagnetic waves
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
How each mode of heat transfer varies with change in temperature?

What is the transfer of energy when molecules bump into each other through contact?
The energy that is transferred when molecules bump into each other is called conduction. Conduction is the transfer of heat energy between substances that are in direct contact with each other.
What do you call the transfer of thermal enegry from particles bumping into each other?
That would be a description of heat transfer by conduction.
Which type of heat transfer is by direct contract?
The type of heat transfer by direct contact is called conduction. Heat is transferred through a solid material or between two objects in direct contact with each other. This occurs as the particles in the material or objects collide and transfer energy to each other.
What is the transfer of heat when to objects are not touching?
convection and radiation heat transfer bot occur without either object being in direct contact with each other.
When does Heat transfer occurs in liquid and gasses?
Heat transfer occurs whenever two or more objects of different temperatures are in contact with each other. Spilling hot water on yourself causes heat transfer from the water to you. When you drive your car the hot engine and radiator transfer heat to the surrounding air in order to cool the engine.
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
