Biochemistry is a laboratory-based science, which requires theoretical knowledge of Biology and Chemistry, as well as experimental techniques implemented in laboratories. In order to solve problems related to chemical processes occurring in living organisms, Biochemistry uses the knowledge of laboratory techniques and examines the processes at a molecular level.
To support the ideas and innovative experiments conducted in a lab, Biochemists need specific equipment, instrumentation, materials, compounds, and glassware. One of the most important types of equipment in any type of scientific lab is a loading balance. Weighing balances are essential for accurate and precise measurements. Improper measurements can lead to significant errors and unreasonable results.
There are various types of loading balances, which fall under the three major categories listed below:
- Standard Level Balances – examples are precision and portable balances with the readability down to 1mg.
- Advanced Level Balances – precision balances with the readability down to 1mg. Such balances are more accurate compared to standard level balances.
- Excellence Level Balances – with the readability down to 0.1mg, such balances ensure maximum precision and accuracy. Suitable for weighing small samples.
Different types of weighing balances are available online on various platforms selling laboratory equipment. One of the most convenient ways for online shopping is to order products through Amazon. To make it easier for you to choose a suitable weighing scale for your Biochemistry laboratory, here are the top 10 loading balances that are available on Amazon.
