Incorporating biological and chemical concepts, Biochemistry aims to solve and provide an explanation for chemical processes occurring in a living organism. As a laboratory-based science, Biochemistry studies how the chemistry of life works through the implementation of various techniques as well as proper equipment.
In a typical Biochemistry lab, you will see dozens of glassware, a wide array of chemicals, spectrometers, moisture analyzers, centrifuges, analytical balances, and many other instruments. In this article, we will focus on a typical moisture analyzer, its purpose, characteristics, and common application options. Besides, we will list the top 10 moisture analyzers for your Biochemistry lab that are available on Amazon.
Moisture is a liquid (water, alcohol, etc.) diffused in small quantities in the form of a vapor. On the other hand, the moisture content is the amount of this liquid in a particular material. Moisture content is an essential characteristic of various products, including but not limited to food, cosmetics, healthcare products, and medicaments. Moisture content is responsible for the physical properties and the quality of a given product. Therefore, analyzing moisture content is very important.
A moisture analyzer (commonly referred to as a moisture balance) is a special instrument used for the determination of the moisture content in a substance. Consisting of 2 major units, heating and weighting units, a moisture analyzer implements the “loss on drying” method through which it measures the weight of a sample, then heats it up, and measures the weight of the dried sample again. Using this technique, the moisture content is determined by simply considering the weight loss of the dried sample.
Moisture analyzers are used in various types of laboratories, including Biochemistry labs. If you are looking for a moisture analyzer for your Biochemistry lab, the following are the top 10 options that you can purchase on Amazon.
