ümarpõhjakolvid

ümarpõhjakolvid, also known as round-bottom flasks, are a type of laboratory glassware characterized by a spherical bottom. This shape is designed to allow for uniform heating and boiling of liquids, as well as to prevent the buildup of solids or precipitates. The rounded bottom also provides increased mechanical strength compared to flat-bottomed flasks.

These flasks are commonly used in a variety of laboratory applications, including distillation, reflux, and general chemical reactions. Their smooth, rounded interior surfaces minimize the risk of charring or sticking of residues, making them ideal for experiments involving viscous or heat-sensitive materials. The uniform wall thickness also contributes to their durability and resistance to thermal shock.

ümarpõhjakolvid are typically made from borosilicate glass, which offers excellent resistance to chemical corrosion and thermal stress. They come in a wide range of sizes, from small laboratory-scale flasks to larger industrial-scale vessels. The neck of the flask is usually straight and designed to accept stoppers, adapters, or other ground glass joints for connection to other apparatus. Their versatility and robust design make them an indispensable tool in chemistry and related scientific fields.
