product description
The constant pressure separatory funnel is a kind of separatory funnel. Like other separatory funnels, it can perform operations such as liquid separation and extraction. Different from other separatory funnels, the constant pressure separatory funnel can ensure that the internal pressure remains unchanged. First, it can prevent back suction. Second, it can make the liquid in the funnel flow down smoothly. Third, it can reduce the impact of increased liquid on the gas pressure. , so that it is more accurate when measuring the volume of gas.
Advantages of PTFE constant pressure separatory funnel
1. The material is made of high-purity experimental grade polytetrafluoroethylene, which is pure and
2. Can be used repeatedly and for a long time to ensure low background
3. Resistant to strong acid and alkali, especially hydrofluoric acid
4. No dissolution or precipitation
5. High and low temperature resistance (-200 to 250°C), and better deformation resistance and recoverability at high temperatures
6. Plastic products, anti-falling
Applicable environment
Generally, a constant pressure funnel is used in a closed system, such as most organic synthesis experiments, because the organic solvent is volatile and needs to be isolated from air (oxygen). The constant pressure dropping funnel is closely connected with the flask (or other reaction vessel) in the above experiments (generally with standard grinding mouth), and the funnel should also be sealed with a stopper. In addition, because the constant pressure dropping funnel is a conventional instrument for synthetic experiments, all of which are standard grinding ports and easy to connect, some dropping processes that do not require closure or loose conditions (such as adding water) are also commonly used constant pressure dropping funnels.
Sometimes when measuring the volume of gas, constant pressure funnels are often used to eliminate the influence of air pressure caused by liquids, which can reduce errors. In addition, using a constant pressure funnel can make the liquid in it flow out better, and can also speed up the experiment process.
