From food to cosmetics and medication, samples are often tested for bacterial contamination. It’s important to measure quantities specific quantities to get accurate results, especially since multiple smaller samples are better for testing that a single big sample. Depending on the sample type and the bacteria tested, the samples sizes can be regulated and require specific amounts to be tested for the test to be legally compliant. Some foods, for example, must be blended, mixed or crushed and measured again after processing. Then sample is then mixed with various components (such as yeast) and the finished mixture is incubated and tested for microbial growth.
Which features should you look for?
Acute precision and excellent accuracy are essential, since the quantities studied can be very fine. A formulation feature, as well as percentage weighing, can be very useful when creating media, especially if the balance lets you store the recipes like our Solis analytical balance does. A preset tare feature, included in Equinox analytical balances, can speed up tasks that use the same containers.
