Background technique

[0002] In conducting scientific research experiments in life sciences, the separation of components of scientific research solutions is often accomplished by using a separatory funnel under aseptic conditions in a clean bench. There is a need to use a funnel to inject a test solution into a container of a smaller diameter, or to add a filter to the funnel to complete the filtration of the test solution.

[0003] In the above-mentioned scientific research operation by means of a separatory funnel or a funnel, it is necessary to maintain the vertical position of the separatory funnel or funnel in the clean bench. Therefore, people usually place a funnel bracket that can be shared by a separatory funnel or a funnel on the surface of the clean bench. To ensure the stability of the bracket after insertion into the funnel, the funnel bracket generally has a larger base area. The crowded condition of experimental samples, laboratory reagents and laboratory equipment appeared on the ultra-clean bench surface where the original area was not large. The crowdedness of these experimental samples, experimental reagents, and laboratory equipment on the surface of ultra-clean benches can hinder the rapid and efficient implementation of scientific research experiments, affecting the accuracy and accuracy of scientific research experiments. Serious paralysis can lead to the failure of scientific research experiments.
