Lab Measuring Cup
The function of the Lab Measuring Cup is as a liquid volume measurement tool that does not require high accuracy, for example reagents / reagents for qualitative chemical analysis or for the manufacture of secondary standard solutions in titrimetric / volumetric analysis. There are various sizes of this measuring cup, ranging from 5 mL to 2 Liters. A measuring cup is a device used to measure the volume of a solution that is shaped like a funnel or glass that has a variable size of milliliters.
Lab Measuring Cup is made of polypropylene due to good chemical resistance or polymethylpentene for transparency, it makes the glass lighter but more fragile than glass, so it should not be used to measure solutions / solvents in hot conditions. Pay attention to the meniscus when reading the scale. The difference between measuring cup and beaker is, measuring cup is a measuring tool while the chemical cup is a storage device. The correct use of these two beakers will help you greatly in the laboratory.
How to use Lab Measuring Cups
There are a number of things to consider when making measurements with this tool, such as:
To measure the volume of a colorless solution, you must pay attention to the lower concave meniscus border. Measuring cup should be placed on a flat area and the meniscus is read parallel to the eye.
To measure the volume of mercury, you must pay attention to the convex meniscus boundary that is seen parallel to the eye and place the measuring cup on a level plane.
