How can a Bunsen burner be used to maintain a sterile field in a laboratory setting?
A Bunsen burner can be used to maintain a sterile field in a laboratory setting by sterilizing equipment and surfaces through the application of high heat. The flame from the Bunsen burner can be used to sterilize tools, such as forceps or scalpels, by passing them through the flame before use. Additionally, the heat from the Bunsen burner can be used to create a sterile environment by burning off any contaminants in the air.
What are the differences between a meker burner and a Bunsen burner in terms of their functionality and applications in laboratory settings?
A meker burner produces a hotter and more focused flame compared to a Bunsen burner, making it suitable for tasks requiring high heat, such as melting metals. Bunsen burners are more versatile and commonly used for general heating and sterilization purposes in laboratories.
Why do you use the Streak Plate Technique in microbiology?
You first inoculate your loop with bacteria and streak a few times across your plate, heat your loop on a bunsen burner to sterilize it and let the loop cool to. Bring your loop back onto where you previously streaked a few times swiping back and forth....heat loop again to sterilize and let it cool. Then the last and third time take your inoculating loop back on where you streaked last time back and forth a few time across the plate always turning your plate 90 degrees. Always remember to stay close to the bunsen burner so you are in the sterile area of the flame to prevent any unwanted contamination of your bacteria. After your media is incubated you should notice 3 streak marks and the third streak mark should be the most dilute where the bacterial colonies are separate and easily observed and can be used further, if needed.

Which british scientists discovered the first anti biotic?
Sir Alexander Fleming, a Scottish bacteriologist, is credited with the discovery of the first antibiotic, penicillin, in 1928. He observed that a mold (Penicillium notatum) inhibited the growth of bacteria in a petri dish, leading to the identification of penicillin as an effective treatment for bacterial infections.
Why do we need to a Bunsen burner in aseptic techniques?
A Bunsen burner is used in aseptic techniques to create a sterile environment by providing a source of heat for sterilizing tools, such as inoculating loops and needles. The flame from the Bunsen burner can be used to sterilize the equipment before and after use to prevent contamination during experiments or procedures.
Flaming an inoculating loop?
There is no "set" time limit. For proper aseptic technique, you should wait until the inoculating loop/needle is visibly red so that all organisms are dead, etc.
What is the purpose of working near Bunsen burner?
The purpose of working near a Bunsen burner is to provide a controlled source of heat for tasks such as sterilization, heating solutions, or conducting chemical reactions in a laboratory setting. The Bunsen burner's flame can be adjusted to produce different levels of heat to suit the specific needs of the experiment.
What is a gas tap used for on a Bunsen burner?
The purpose is to control the combustible gas flow.
What is the purpose of a heat proof mat when using a Bunsen burner?
The purpose of a heat-proof mat when using a Bunsen burner is to protect the work surface from the intense heat generated by the flame. It helps prevent accidental burns, scorching, or damage to the surrounding area. Additionally, it provides stability for the Bunsen burner and prevents it from tipping over.
What is the uses of Bunsen burners?
A Bunsen Burner, is piece of equipment particularly used in a science lab. The Bunsen Burners creates a gas flame which is used to assist in experiments. The Bunsen burner originating from 1852, given the name by Robert Bunsen.
What is the function of a gas intake tube of a Bunsen burner?
The purpose is the introduce the fuel gas in the burner.
Chemisrty lab tripod is used for what purpose?
for placing things on and a Bunsen buner underneath e.g a beaker
When did Robert Bunsen invent the Bunsen burner?
Robert Bunsen invented the Bunsen Burner in 1867.
Did Bunsen create the Bunsen burner?
Robert Bunsen invented the Bunsen burner if that is what you mean?
Did Robert Bunsen make the Bunsen burner?
No, Robert Bunsen did not invent the Bunsen burner. It was actually invented by Michael Faraday in the 19th century. The Bunsen burner is named after Bunsen as he helped popularize its use in laboratories.
What is the laboratory tool that its purpose is heating and boiling?
this may be either a gas powered Bunsen burner or an electric hot plate
