An analytical balance (or chemical balance) is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg resolution or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation.
Mettler Toledo produces precision laboratory instruments used for sample preparation, synthesis, analytical bench top activities, material characterization, and in-line measurement. Their portfolio includes laboratory balances , liquid pipetting solutions, automated laboratory reactors with real-time analytics, titrators , pH meters , process ...
When using the triple beam balance, it is recommended that one start with the lowest level of precision (e.g 100 gram increments). For example, if an object weighs 327 grams, the 100 gram pointer will drop below the fixed mark on the 4th notch (400g); it will then need to be moved back to the third notch (300g).
Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...
Low-nitrogen weighing paper: Low-nitrogen weighing paper is the most common type of weighing paper that is used for analytical balances in the labs. The smooth texture prevents gunking up and absorption of samples on the paper. [4] Sulfur-free weighing paper: [5] Sulfur-free weighing paper is usually used for weighing food materials.
