What are the general rules in the use of cleaning equipment?
Rules for the use of cleaning equipment depend on the type of cleaning equipment is being used. Using the equipment safely would be a general rule. Keeping the equipment clean and in good condition is another general rule. Other general rules might be storing the equipment properly, storing chemicals properly, and using the correct chemicals.

You can use a simple balance.

Who was Dr Cecil Paine?
He was the first person ever to use penicillin, he worked with Sir Alexander Fleming.
What type of math did Alexander Fleming use?
At a guess exponentials, series and statistics would have been important in studying micro-organisms.
Who is Alexander Fleming and what he do?
Fleming discovered that penicillin was a mould that could kill certain types of bacteria that caused disease. The Use of penicillin did not begin until the 1940s when Howard Florey and Ernst Chain made a powder form of penicillin
What could be treated as a result of Alexander Fleming's discover of penicillin?
Alexander Fleming's discovery of penicillin came about by accident. Fleming was an untidy worker, often leaving his equipment uncleaned. When he went away for a holiday during 1828, he left a clutter of plates growing various bacteria lying about his desk. After he returned, whilst working on an influenza virus he noticed that mould had grown on a staphylococcus culture plate. Not only that, the mould had created a bacteria-free circle around itself. Working on an hypothesis, he experimented further to determine that even a weaker-strength mould culture prevented growth of staphylococci. Thus, Fleming initiated the development and practice of antibiotic therapy for infectious diseases.
Who was 'mouldy mary' and what part did she play in the pencillin story?
'Mouldy Mary' was Mary Hunt, a lab assistant who played a crucial role in the discovery of penicillin by Sir Alexander Fleming. She maintained the cultures of Penicillium mold that Fleming used in his experiments, ensuring their viability and purity. Hunt's dedication and attention to detail helped Fleming in isolating and developing the penicillin mold, paving the way for its use as the first antibiotic.
How do you use pencellin?
er, do you mean penicillin? penicillin is used as a antibiotic that tends to form in...mold. Many pain relievers or over the counter drugs contain this "chemical". Alexander Fleming discovered this thing with the microscopes of the time.
How did Alexander Fleming change people's lives?
In 1928 bacteriologist Alexander Fleming made a chance discovery from a discarded contaminated petrie dish that the mould that had contaminated the experiment turned out to be a powerful antibiotic, penicillin. Florey and Chain worked out how to manufacture the penicillin and use it as a drug to combat bacterial infections, thus saving many lives.
Who is credited with with inventing penicillin?
Originally Englishman Alexander Fleming noticed the activity of penicillin when it had accidentally contaminated a culture he was working on. He made a note of it and did no further work with it. Howard florey an Australian and Ernst Chain got wind of Flemings discovery and went to work to isolate penicillin. They succeeded in producing the drug. however it took the backing and infrastructure of the US department of defense to bring the final development of penicillin to fruition. Once all of the work was completed Fleming stepped in to share in the credit for the discovery.In 1928, Sir Alexander Fleming observed that colonies of the bacterium Staphylococcus aureus could be destroyed by the mold Penicillium notatum, proving that there was an antibacterial agent there in principle. This principle later lead to medicines that could kill certain types of disease-causing bacteria inside the body. At the time, however, the importance of Alexander Fleming's discovery was not known. Use of penicillin did not begin until the 1940s when Howard Florey and Ernst Chain isolated the active ingredient and developed a powdery form of the medicine.Penicillin wasn't invented. It was discovered by accident by Sir Alexander Fleming in 1928 that penicillin killed bacteria. It was discovered at St Mary's Hospital, England.Wikipedia lists Sir Alexander Fleming discovering Penicillin. It was further developed by Howard Walter Florey.Alexander Fleming.Alexander Fleming. It might be apocryphal (almost true !) that had Pennicillin not been invented twice as many people would have died in WW2 than actually did.AnswerFleming from England
Who invented penicellin?
Penicillin is a group of antibiotics that is derived from the Penicillum fungus. It was discovered by a Scottish scientist, Alexander Fleming, in 1928. However, the development of penicillin for medical use is attributed to Howard Walter Florey, Ernst Chain, and Norman Heatley.
How did Alexander Fleming impact your world?
Alexander Fleming made a great contribution to the world though an accident led to the discovery. he noticed in a petri plate of his that there was a clearing area of bacteria around a golden yellow mold. this mould was penicillin species . therefore he thought that the bio product released by penicillin is responsible for the restriction of growth for the bacilli species.Because of this, Howard Florey and Ernst Chain managed to concentrate penicillin and make it effective to use as a antibacterial drug. It is currently a medical standard today
What tools and equipments does a cytologist use?
Some of the tools and equipment used by a cytologist are a microscope, slides, and neutral solutions. A cytologist studies cells and their presence of mutations due to cancer.
