When performing chemical tests, different instruments must be used, among which the constant pressure drip funnel and the constant pressure separating funnel are often confused. Let's take a look at the subtle differences.
1.Dripper hopper at constant pressure:
A droplet funnel under constant pressure is a device that is often used in experiments to accurately drop a solution into the reactor. This device is generally made of glass, which allows water droplets to slowly come from the container**. Compared to conventional dispensing devices, the device can accurately control the drip rate by adjusting its control valve, so that the drip rate remains relatively stable.
2.Constant pressure separating hopper (voltage distribution):
The constant pressure separating funnel, also known as the constant pressure dispensing device, is a device that separates two incompatible fluids. The equipment maintains a certain differential pressure during fluid separation, which enables fast and efficient separation of two-phase fluids. The unit is generally equipped with two separate outlets for discharging the bottom and upper liquids.
Key differences: In terms of function, the constant pressure drip funnel is mainly droplets, and the constant pressure separating funnel is separated from two incompatible liquids as raw materials. The constant pressure hopper is generally a single discharge, and the constant pressure liquid hopper has two separate outlets to discharge two different fluids. Usage: The constant pressure feeding funnel is suitable for the occasion of precise measurement of the solution, and the constant pressure separating funnel is suitable for the rapid separation of two-phase fluids.
Conclusion: In the teaching process, how to correctly select various instruments is the key to ensure the teaching effect. Constant pressure separating funnels are a commonly used fluid distribution device, and they play their own special function in the test process. Understanding the differences between these two methods allows us to be more flexible in the use of a variety of instruments, thus guaranteeing the accuracy and reliability of our results.
