e/m Apparatus + Power Supply Combo

SAVE WITH THIS COMBO DEAL!

This combo includes:
• e/m Apparatus
• e/m Tube
• Power Supply for e/m Apparatus

Introducing our popular e/m Apparatus! Its body is made of durable high quality black acrylic resin. The e/m Apparatus allows students to clearly observe the effects of electric and magnetic fields on an electron stream. This compact instrument provides students a dramatic and visually pleasing experience. The large orbital electron path is circular and Helmholtz coils are integrated.

The e/m Tube has a built-in engraved glass rod with a scale along the central axis. This eliminates parallax when taking diameter readings of the electron orbit. You can observe the entire experiment through the front view hole or rear sliding panel.

SPECIFICATIONS:
• Vacuum Tube: - 130mm diameter - Helium gas - Integrated phosphor scale
• Helmholtz Coil: - 300mm diameter - 1mm wire 130 turns - Two parallel mounted coils with variable resistors to adjust current
• Anode: 200-500V
• Heater: 6.3V/1A
• Helmholtz coil: 12V DC/2A
• Durable high quality black acrylic resin body
• Sliding back cover
• Power Supply Sold Separately
