Description
Technical Parameters
Round conical flask, also known as conical flask or Erlenmeyer flask, is a common glass instrument in chemical laboratories. It is a titration reactor made of hard glass with a triangular longitudinal section. Its small mouth and large bottom are conducive to sufficient reaction and less splashing of liquid during oscillation during titration. This container can be heated on a water bath or electric stove, and has a flat bottomed conical shape with a wide bottom and a narrow top. It has a cylindrical neck and an opening wider than the neck above. Sometimes it can be closed with a stopper made of cork or rubber. This instrument was invented by German chemist Richard Erlenmeyer in 1861 and has been widely used in chemical experiments due to its unique shape and practicality. As a common instrument in chemical laboratories, it plays an important role in experiments with its unique shape and excellent performance. Through continuous innovation and development, conical bottles will become more intelligent, multifunctional, and environmentally friendly. In the future, with the advancement of technology and the continuous changes in experimental needs, conical jars will continue to play an irreplaceable role in chemical experiments.

Diversified applications of round bottomed conical bottles
The conicel flak with a round bottom plays an important role in the study of chemical reaction kinetics. By changing the concentration of reactants, temperature, or type of catalyst, experimenters can conduct a series of comparative experiments in conicel flaks to study reaction rates and mechanisms. Due to the shape and material of the conicel flak, it can provide a uniform reaction environment, making experimental results more accurate and reliable.
In solvent extraction and separation experiments, conicel flaks with round bottoms are also commonly used as containers. The experimenter can mix the solution containing the target compound with the extractant in a conicel flak, shake or stir to ensure sufficient contact between the two, and then let it stand and separate into layers. Due to the shape and material of the conicel flak, it can facilitate the mixing and separation of solutions, while reducing the splashing and waste of solutions.
Round bottomed conicel flaks also play an important role in sample preparation and pretreatment processes. The experimenter can dissolve the test sample in an appropriate solvent and then perform stirring, heating, or filtering operations in a conicel flak to prepare a sample solution that meets the analysis requirements. Due to the shape and material of the conicel flak, it can facilitate the dissolution, mixing, and filtration of samples, while reducing sample loss and contamination.
Round bottomed conicel flaks are also widely used in biochemical experiments. For example, in an enzymatic reaction experiment, the experimenter can mix the reactants such as enzyme, substrate, and buffer in a conicel flak, and study the rate and mechanism of the enzymatic reaction by controlling conditions such as temperature and pH. In addition, in experiments such as protein purification and cell culture, conicel flaks with round bottoms are often used as containers to provide a suitable reaction environment and operating space.
In the field of environmental science, conicel flaks with round bottoms are also used for processing and analyzing environmental samples. For example, in water quality monitoring experiments, the experimenter can add the collected water sample into a conicel flak and detect the concentration of pollutants in the water by adding appropriate reagents and conducting chemical reactions. In addition, in experiments such as soil analysis and atmospheric pollutant monitoring, conicel flaks with round bottoms also play an important role.

Round conical flask, with their unique shape design and excellent performance, have demonstrated extensive potential and value in chemical experiments. The following is a detailed expansion of its application scenarios:
Titration experiment:
As the most common application scenario for conical jars, titration experiment is undoubtedly a stage for them to showcase their skills. During the titration process, a conical jark is used to hold the test solution, and the standard solution is accurately dripped through a burette until the reaction reaches the predetermined endpoint. The shape design of the conical bottle - wide bottom and narrow top, as well as the material made of hard glass, play a key role together. This design not only ensures the stable distribution of titrant in the bottle, preventing splashing and waste, but also improves the accuracy and reliability of the experiment. Meanwhile, the hard glass material can withstand various chemical changes that may occur during the titration process, ensuring the smooth progress of the experiment.
