Holder for Teltron Tube, Type D

This holder is designed specifically for Teltron tubes type D. The tube can rotate 360° about its longitudinal axis, and the base plate is prepared for mounting Helmholtz coils, giving a stable, secure setup that also lets the tube be stored in the holder between experiments. In physics lessons it is used for experiments on electron paths, magnetic fields and the motion of charged particles, where secure mounting is important both for precise measurements and for protecting the delicate glass tubes.
