Lab Equipment - Finding Out Whether the New Pump Will Improve Your Results

Lab Equipment - Finding Out Whether the New Pump Will Improve Your ResultsA chemistry grad student measures the performance of the new pump in his La Jet. He knows that the same pump will be used in many other tests in the lab. The equipment is expensive, so he has to do some comparison shopping. What would you do if you found yourself in the same situation?The student is testing a new pump. The pump he is using is nearly seven years old. When he does his math, it comes out to about twenty-five percent performance improvement, a little less than the usual amount.The previous study was to compare the new pump with some of the other pumps available. The results were that the other pumps performed better in the experiments. The student simply assumed that this is the case. He never asked anyone for their opinions. He just assumed it.When he submitted his report, he did not get the results he was expecting. He should have taken time to look at the results before he submitted his report.T he next time he tests the pump, he'll ask for feedback on the performance of the new pump. He'll also compare the results to those from the last study. The results could turn out to be better or worse.When the pump he is using breaks down and requires replacement, he will find that the results from the last study are relevant in the new test. It might take several years for the pump to break down and require replacement. After that period, he might not find a better pump.If he is a graduate student, he will be curious about whether there will be any improvements in the performance of the pump. If the performance is not better, he will not be too happy. He might try to run another study at the same time. That could take a lot of time and cost more money.He can't let something like that stand in the way of a test. The idea is to perform tests as quickly as possible. That means that he must test different pumps and see what happens. Sometimes, it will help to have more than one test ru n to find out what is going on.
