• Side neck at an angle of 25°

Here are some common uses for a Pear Shape Flask with Two Necks according to DIN standards in a laboratory:

1. Parallel Reactions: The two necks allow for the setup of parallel reactions, enabling researchers to conduct multiple reactions simultaneously.
2. Distillation and Fractionation: The flask is suitable for distillation setups, where different components of a mixture can be collected through the individual necks. This is particularly useful for fractionation processes.
3. Refluxing: Each neck can be used for reflux setups, allowing for the refluxing of multiple reactions simultaneously.
4. Simultaneous Sampling and Analysis: Researchers can use the individual necks for simultaneous sampling or the addition of reagents, facilitating real-time analysis or monitoring of reactions.
5. Temperature Control Experiments: One or both necks can be utilized for inserting thermometers or temperature probes, allowing for precise temperature control in each reaction.
6. Gas Inlet/Outlet: One or both necks can be used as gas inlets or outlets, making the flask suitable for reactions involving gaseous reactants or by-products.
7. Complex Reaction Setups: The multiple necks offer flexibility for designing complex experimental setups that involve multiple reactants, catalysts, or monitoring devices.
8. Multi-step Synthesis: The flask can be used for multi-step synthesis, where different steps of a synthesis process can be conducted concurrently in separate compartments.
