Product Description

High-purity PTFE constant pressure separating funnel 60ml corrosion-resistant  low background

product description

The constant pressure separatory funnel is a kind of separatory funnel. Like other separatory funnels, it can perform liquid separation, extraction and other operations. Different from other separatory funnels, the constant pressure separatory funnel can ensure that the internal pressure remains unchanged. First, it can prevent sucking back, second, it can make the liquid in the funnel flow down smoothly, and third, it can reduce the influence of the 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 polytetrafluoroene, which is pure and pollution-free

2. It can be used for a long time, multiple times and repeatedly, ensuring low background

3. Resistant to strong acid and alkali (corrosion resistance)

4. No dissolution and precipitation

5. High and low temperature resistance (-200 to 250°C), and better deformation resistance and recoverability at high temperatures

6. Plastic products, anti-fall and durable
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.
