Why was the inoculation loop invented?
Plastic disposable loops began to appear in the 1970’s to address the needs of labs without access to gas for Bunsen burners, and also the valid concerns about aerosols of pathogenic bacteria being created by splattering when a used loop is flamed to sterilise it6.
Is nichrome wire reusable?
Reusable Nichrome Wire Inoculating Loops without Handles
These Inoculating Loops are made from high quality twisted nichrome wire. Loops have been designed to slide along agar surfaces without cutting or tearing. Inoculating Loops cool rapidly and are less expensive than platinum.
What do you mean by nichrome?

What is platinum loop?
Platinum loops and needles are used for transferring bacterial cultlres. These loops and needles are made of B&S platinum wire with 15% iridium added for rigidity, permitting a thinner wire for delicate work. Loops are fused to form a “perfect circle” with an inside tolerance of +/-0.02 mm to ensure accurate delivery.
What is the diameter of Nichrome wire loop?
Loop inside diameter is 2.5mm.
How do you sterilize an inoculation loop?
The inoculating loop is sterilised by passing it at an angle through the flame of a gas burner until the entire length of the wire becomes orange from the heat. In this way all contaminants on the wire are incinerated. Never lay the loop down once it is sterilised, or it may again become contaminated.
What is the nutrient material used for culturing bacteria?
Nutrient Agar is a general purpose, nutrient medium used for the cultivation of microbes supporting growth of a wide range of non-fastidious organisms. Nutrient agar is popular because it can grow a variety of types of bacteria and fungi, and contains many nutrients needed for the bacterial growth.
What is the wire loop?

What is the most important part of using a metal loop in transferring bacteria?
Whenever you’re using metal inoculating loops, it is essential to flame and cool the metal loop after every use. It is very important to let the loop cool before you insert it into broth or near a colony, because excessive heat will kill the organisms.
What containers are used to culture bacteria?
This includes blood culture bottles (if placed in plastic carrier), Vacutainer® tubes and swabs. Specimens should be in tightly sealed, leak proof containers and transported in sealable, leak-proof plastic bags.
