AI Technical Summary

Technical Problem

In the existing solid sublimation teaching experiment apparatus, the evaporating dish outlet and the porous filter paper are vertically stacked during the product collection stage, which causes the sublimated solid to easily fall back into the evaporating dish, resulting in product loss and affecting the teaching experiment effect.

Method used

Design a solid sublimation teaching experiment device. By changing the connection structure between the exhaust port of the heating tube and the inlet of the crystallization tube to a horizontal direction, and by setting the cooling zone and the housing cavity of the heating tube out of alignment, the sublimated gas will condense in the cooling zone and fall to the bottom, thus preventing the product from flowing back into the heating tube.

Benefits of technology

This effectively solved the product reflux problem, avoided product loss, and improved the stability and effectiveness of teaching experiments.
