Separatory funnel is used to separate two liquids from a mixture.
This funnel has a small tube at the bottom which often breaks due to poor clamping.
For this reason, this case has been built which allows protection along with the clear view of the separation of liquids inside the funnel
Snap fitting is required for the parts to make sure the parts don't dis-assemble themselves while the funnel falls down. Filing the parts might be required to press-fit the parts easily.
