Silica Crucible Science Classroom Borosilicate glass rectangular convection tube

Borosilicate glass rectangular convection tube at 380 by 300mm with a filling funnel

sized for whole-class visibility of momentum-and-energy conservation through pendulum collisions

exposing the moving parts so students see directly how a DC current drives a rotating magnetic field

sized for storing and pouring photosensitive solids or solutions

and mechanical-systems setups with increased momentum-per-unit requirements

Silica Crucible Science Classroom Borosilicate glass rectangular convection tubeFused silica construction withstands higher temperatures than porcelain, suited for ashing and thermal decomposition work above the porcelain working range in gravimetric analysis.
