By far, one of the most important resources that most laboratory workers and other scientific professionals have available to them is ultimately the data they have to work with. Science is nothing if not very precise — under the right conditions, nearly anything can be understood and controlled to achieve a desired outcome. But if you're working from inaccurate data to begin with, almost everything you do afterward will be tainted in a way that can be difficult, if not impossible, to recover from.
This is ultimately why products like colony counters are so important to lab professionals all over the country. Not only do they make it easy to determine the concentration of microorganisms in a given sample, but they also guarantee that those pros are only working from the most complete and objective data set possible moving forward.
