Application:_..

The tube holder accommodates the entire range of tubes model S designed for practical experiments, along with their accessories such as Helmholtz coils S (1000611) and an auxiliary coil (1000645), and can also serve as the base for the discharge tube S (1000624).

Product Information:_..

The tube holder consists of a base plate with a holder for the tube set at an angle with terminal panel attached. The tail-stock for the neck of the tube contains an octal plug connector and a central bore. Five sockets are electrically connected to the terminal panel with its 4-mm safety sockets. A filament protection circuit is also integrated into the neck brace to prevent excess voltage being applied to the cathode heater circuit and thus protecting the sensitive heater filament from damage. The relay cuts out at a filament voltage of about 10.5 V DC or about 8.5 V AC. It switches back on again when the filament voltage is once again below the limit. Excess voltage is indicated by a red LED.
The base also contains a slot for accommodating Helmholtz coils either transversely to the tube and up to 150 mm away from it or in standard Helmholtz configuration (marked). The ramp at the front of the tube holder accommodates the Helmholtz coils in an axial configuration and also provides a base for the auxiliary coil.
The tube holder is mounted on three rubber feet and is thus unable to slide.
