5530-Flasks, Flat Bottom with Joint, DIN/ISO

• Complies with DIN / ISO 4797 and USP standard

* Non DIN

Here are some common uses for flat-bottom flasks with joints in accordance with DIN/ISO standards:

1. Chemical Synthesis: These flasks are often employed in chemical synthesis reactions. The joints allow for the attachment of other glassware, such as condensers, reflux systems, or addition funnels, facilitating various chemical processes.
2. Distillation: Flat-bottom flasks with joints are commonly used in distillation setups, where different components of a liquid mixture are separated based on their boiling points. The joints allow for the connection of distillation columns, condensers, and other necessary components.
3. Heating and Reactions: The flat bottom of these flasks provides stability on heating surfaces, making them suitable for heating and performing reactions. The joints allow for easy connection to other glassware or apparatus.
4. Sample Preparation: In analytical chemistry, these flasks may be used for sample preparation, including processes such as evaporation or concentration of solutions, especially when additional glassware needs to be attached.
5. Extraction: Flat-bottom flasks with joints can be utilized in extraction processes, where components are selectively removed from a sample. The joints enable the connection of separatory funnels or other extraction apparatus.
6. ISO and DIN Methods: Specific ISO or DIN methods may specify the use of flat-bottom flasks with joints for particular tests or analyses. These standards often provide guidelines for the types of glassware and equipment to be used in specific laboratory procedures.
