Product applications
The round bottom flask has a wide range of applications in chemistry,biology,and other fields.Here are the detailed instructions.
(1) Chemical synthesis reaction
Organic synthesis: such as the synthesis of esters, amides, etc. During the synthesis process, the round-bottomed flask can provide a stable reaction environment, so that the reactants are fully mixed and reacted.
Inorganic synthesis: Preparation of certain inorganic compounds, such as complexes.
(2) Distillation and fractionation operations
Used to separate and purify liquid mixtures, by controlling the temperature, so that the components of different boiling points have evaporated and condensed. For example, different fractions are separated from petroleum.
(3) Reflux reaction
When a reaction requires a specific temperature for an extended period and needs to prevent the volatilization of reactants or solvents, a reflux device can be used, the round bottom flask plays a crucial role in this.For example,in a reflux process in certain drug reactions.
(4) Dissolution and dilution
Solid substances can be dissolved in a round-bottomed flask with a certain concentration of solution.
(5) Sample heating treatment
In analytical chemistry, samples are pretreated with heat for subsequent detection and analysis.
(6) Experiment on Microbiology
Cell culture：It can be used to configure media for cell culture
Enzymatic reaction:We can study the enzyme activity and reaction conditions
