Conducting experiments is very expensive because the instruments, test kits, and equipment needed could cost up to tens of thousands of dollars. Samples can also vary, from those that can be easily obtained in your backyard up to those that can only be obtained in the deepest parts of the sea. Devices that can help analyze your data are also costly. And of course, the research chemicals you have to use in every step can cost from hundreds to thousands of dollars. Hence, scientists should always be really careful, precise, and accurate in order to avoid wasting resources. They should also pay attention to the reagents and solutions they are going to use in order to prevent repeat experiments that are caused by bad or contaminated chemicals.
Bad reagents are those contaminated ones, those that have formed weird precipitates, have turned into an unexpected color, or have drastically changed their pH. These can cause an experimental failure either in the middle or at the end of a research study, which is a very huge loss for both the researcher and the laboratory. Time, money, sweat, blood, and tears are all wasted due to a very undeserving cause. If this is the only reason as to why one should buy research chemicals from trusted suppliers, then it is all worth it. A lifetime’s worth of hard work and a billion dollars’ worth of ideas may all be depending on these chemicals anyway.
In order to buy research chemicals that are of high quality, one should consider manufacturers and suppliers that have superior standards. They should also be boasting about manufacturing and selling certifications and licenses. Their high quality reagents and solutions should also be proven and tested by more than one independent research group, and their descriptions and specifications should match their products’ function and performance.
Having good research chemicals in the laboratory can assure researchers and scientists that their experiments are running on a good gas that can last for months to years and that can accommodate a dozen different experiments at once. Moreover, if scientists opt to buy research chemicals that are of high quality, they can be assured of stable products that will not degrade easily, even with fluctuating pH and temperature. Not only are those products helpful during various experimental conditions, but they can also be salvaged if that one-in-at-thousand chance happens wherein something goes wrong with your storage equipment.
Other examples of drastic effects of bad reagents include getting the wrong numbers and results during analytical procedures, obtaining the opposite of the expected outcome, and very high standards of deviation. In microbiology, your desired bacteria may not grow well in your prepared media or it will take a longer period for it to grow. It may not even totally appear or a completely different species, such as undesirable molds and yeasts, would grow instead. In molecular biology on the other hand, your DNA and RNA extraction protocols could totally fail. Either you will get a very insignificant amount of nucleic acids, an impure product, or you will not get anything at all. The same can also happen in chromatography. You will not be able to isolate your desired product or still get an impure even after a long and tedious process.
Bad research chemicals can be avoided by simply taking a closer look at what different suppliers have to offer and also by being really careful during the reagent preparation step of every experiment. You must also be ready to spend some cash in order to get and buy research chemicals that will satisfy all your needs.
