Vacuum Apparatus
Spectrum Tubes
Made of glass, 26 cm long overall, narrowed to capillary width for 8.5 to 10 cm of length. Metal wires holding the electrodes are sealed through the ends and welded to metal caps, which have loops for connecting wires.
For use with Spectrum Tube Power supply PH61025.

Vacuum Apparatus
Deflection Tube
To show deflection of cathode rays by a magnet. Horizontal tube is fitted with a fluorescent aluminium plate, the cathode side of which is bent at right angle and is provided with a slit. Cathode rays passing through the slit cast a sharp and bright shadow across the aluminium plate. When a magnet is brought near, the cathode rays deflect sharply.
*Additional power supply of 12kV is required to operate.

Vacuum Apparatus
Magnetic Deflection of an Electron Beam
Designed to observe how an electron beam is affected by a magnetic field. The power supply holds a deflection tube with a cathode and an anode. The cathode end features a phosphorous coating, which glows when exposed to electrons. As we bring a magnet (not supplied) near, it causes the electron beam to move in a perpendicular direction to show the deflection of an electron and how a cathode and anode both work.

Vacuum Apparatus
Canal Ray Tube
To show positive rays. Vertical type, with two fused discs at each end and a perforated cathode in the center through which canal rays pass. The space below the cathode is filled with characteristic glow of cathode rays and the upper portion has canal rays. A magnet brought near the upper portion will repulse the rays, showing the positive nature of the canal rays.
