RADO-type Desktop cloud chamber B-112
(Dry ice cooling type)
FOB Price 700,000 JPY
B-112We can observe tracks of natural radioactive rays in about 5 minutes from a cooling start. 441 pins (patent pending) in the backside of the observation chamber base stick into dry ice and raise chilling effect. By "the alcohol removal that piled up in the base and alcohol supplement " once in one hour, we can observe about continuation 5 hours. Because of 288 super high brightness LEDs, we can observe clear tracks in the bright room. As the top surface is used heater glass, glass is not clouded and we can observe tracks clearly. Because heater glass is not fixed, we can easily set sources and magnets to the observation area. And it is possible to carry out various experiments (experiment of half life , or the Lorentz force law by the magnetic field with the beta beam) easily.There is a small hole to insert a source at the side of the chamber.

RADO-type simple cloud chamber experiment set D-113
(Dry ice cooling type)
FOB Price 32,000 JPY
D-113
About 1kg crushed dry ice is used for cooling this cloud chamber. Observation area is so wide that we can observe the tracks of natural radioactive rays without using any sources. In addition, we can easily perform experiments by useing various sources. Observation by the group of several students is possible with one set. Because the device is simple, and the handling is easy, this is the most suitable for student experiments. We can observe tracks clearly by using two super high brightness LED lights.
Device and accessories of D-113 Device and accessories of D-113
■Glass observation chamber (inside diameter 180mm)
■Glass chamber lid with a small hole ( for the insertion of radon gas )
■Hard styrofoam tray

RADO Peltier Cooling Cloud Chamber E-114FOB PRICE 1,400USD
E-114Name: RADO Peltier Cooling Cloud Chamber E-114
Cooling method: Peltier element cooling
Observation surface: Circular (diameter 75 mm)
Illumination: 12 high brightness white LEDs
Size: About W220×D170×H220 mm
Body weight: About 2kg
Supply voltage: AC100 ~ 120V or AC200 ~ 240V
Power consumption: About 70W
Using liquid: Ethanol
Radiation source : 220Rn supply mantle and ceramic monazite ball
・It is a Cloud Chamber that uses a Peltier element to cool and observe the tracks of radiation.
・With a wide observation surface of 75 mm diameter, you can observe many tracks.
・5 to 6 students can observe simultaneously.
・Tracks of natural radiation are observed.
・The tracks will start to appear in about 3 minutes after turning on the power.
・It is possible to add ethanol from the bottle with one push without interrupting the observation.
・Since the observation surface is illuminated with 12 super high brightness LEDs, the tracks are clearly visible and no darkroom is required.
・Since residual ions are removed by applying a voltage to the observation surface, fine tracks such as beta rays can be observed.
・A mantle for 220Rn supply and a ceramic monazite ball are attached as radiation source samples.
・Because it has low power consumption, it is possible to operate multiple units at the same time.
