Frequently Asked Questions

To handle and move a heated crucible securely, one needs a crucible holder, such as crucible tongs. Crucibles are tiny, cup-shaped containers used to heat chemical compounds to high temperatures. They are composed of metal or porcelain, two materials that are resistant to heat. When handling hot crucibles, the holder shields the operator from burns.

In the scientific field, a flask is used to measure and store liquids, especially in a laboratory setting. Although there are several types of flasks, volumetric flasks are crucial for precise dilutions and solution preparation because they are specifically made for accurate volume measurements.

A flask's primary purpose is to store, confine, collect, and occasionally measure the volume of liquids for a variety of laboratory activities, such as mixing, heating, cooling, dissolving, precipitating, boiling (as in distillation), or analysis.

A flask and a beaker differ primarily in the form of their sides. Flasks have sloping, or conical, sides, whereas beakers have straight sides. The difference influences how they are used in certain laboratory procedures.

Erlenmeyer, Florence, and volumetric flasks are the three primary varieties of laboratory flasks. 

  • Erlenmeyer Flask: Perfect for mixing and stirring liquids, these flasks feature a conical form, a broad neck, and a flat bottom.

  • Florence Flask: These flasks are frequently used for heating and boiling liquids because of their longer necks and rounder bodies.

  • Volumetric flasks are used to make exact dilutions and solutions because of their thin necks with calibration marks and their ability to measure volumes precisely. 

Bottles used to hold different chemicals in liquid or powder form are commonly referred to as media bottles or reagent bottles in the field of chemistry. To keep the contents contained, these bottles—which can be composed of glass, plastic, or borosilicate glass—are frequently sealed with caps or stoppers.
