A balance is a crucial and fundamental piece of equipment for any laboratory. The first and foremost consideration in shopping for a Laboratory Balance is clarity of thought on use and application. The purpose of the balance, the type of materials, and the amount of materials all factor into the choice of instrument. For solid, inert materials of a kilogram or more, an industrial balance would be the right choice. For measuring microgram quantities of pharmaceutical compounds, a precision Analytical Balance would be necessary.
Similarly, consider the laboratory and the overall environment. For a dusty environment, such as a factory floor, look for balances that are sealed against outside materials. If there are drafts, vibrations, or temperature fluctuations, a sensitive analytic balance may not function well. Some balances come with their own enclosures, to keep contaminants out.
If the work being done requires certification, or involves toxic or radioactive materials, regulatory and personnel training requirements may need to be satisfied. In addition, the frequency of use will influence the choice. A balance that is used all day, every day, needs to be very durable and reliable.
