Tube speed of the bubble, 30 per case, A bubble in each tube rises at a constant speed that depends on the type of fluid, the angle at which the tube is inclined, and to some extent, the temperature.This set provides students with practice setting up experiments and graphing data.
Tube holder made of robust plastic for holding D-series electron tubes. Stand has a wishbone, 360deg rotating clamp made of heat-resistant plastic. On rubber feet to prevent slipping. Dimensions: approx. 230x175x320 mm3 Weight: approx. 1.5 kg
Tube holder to support all S series (student) electron tubes for easy and safe operation. The five pin sockets for the tube are concealed inside the tube holder. A cathode protection switch is integrated into the tube holder, to protect the heated cathode from excessive voltage.
