Medical professionals, research scientists, and other scientific professionals do a lot of testing with various microorganisms. They will put those organisms in petri dishes or other containers so that they can test to see if a particular organism will be destroyed by a certain substance or to try to see what kind of bacteria is making a person or animal sick. The ability to be able to see what the microorganism is, and how much of it there is, can help save lives or improve the standard of living for the world. The problem comes when it's time to count whatever is growing in the dish. There are various ways to do so. One is to do it manually, while another is to do it automatically using something like a colony counter.
A colony counter is a machine that the container containing the microorganism can be loaded into. The counter will then take a look at the sample and give an estimate of how much of the organism there is in the container. It does this by counting all the colonies that happen to be in the dish. Alternately, the researcher can work with the machine and mark the colonies and then let the machine do all the work of counting. This machine comes with a lot of benefits.
One benefit is that the machine will have a higher accuracy rate than a human will. There is less of a risk of missing a small colony when counting or double counting one. It can be very important to make sure that a very accurate count of whatever microorganism is in the dish happens due to many reasons, including making sure that a patient has the right amount of medication or right treatment to handle whatever is going on.
Another benefit is that the researcher or medical professional can work on other things while the colony counter is doing its job. That could include setting up another sample to be checked or going to check on a patient. That benefit can make the research or medical professional more efficient because they are able to move on to other things.
Knowing what kind of microorganism is being grown and how much of it there is in a dish is really important. A colony counter can help make sure that finding out how much of any given organism is in a container happens quickly and efficiently.
