The Lascells Cloud Chamber is the perfect alternative to existing unreliable and time consuming dry ice variants. The chamber is self-contained and thermoelectrically cooled. The chamber requires no dry ice or water; the only setup necessary is the addition of isopropyl alcohol and connection to a mains socket. The chamber contains an integrated power supply and illumination of the chamber is provided by a high intensity LED. Using the provided source, tracks should be visible within 10 minutes. Once running the cloud chamber can be made to run for extended periods by adding more alcohol through the access provided in the lid.

This compact unit from Lascells provides an elegant method of demonstrating the wave phenomena of reflection, diffraction, refraction and interference with none of the setting-up problems usually associated with ripple tanks. The concept has been further developed to offer new features and simplicity in this MkIII design. The unit is completely self-contained with the translucent viewing screen hinging away to reveal a 12cm water tank. The tank is removable for ease of use and has an integral multi-faceted beach which virtually eliminates unwanted reflections. Illumination is from a high intensity built-in LED which can be automatically strobed in sync with the waves to give perfectly stationary images, or switched to allow the user independent control of the wave and strobe frequencies giving the impression of wave motion across the viewing screen. The unit is supplied with three robust dippers which can be easily adjusted to suit the depth of water being used. A selection of barriers shapes and lenses are also provided to enable reflection, refraction, diffraction and interference along with the focussing properties of lenses to be demonstrated. All of the accessories can be stored neatly inside the unit when not in use.

This Microwave Transmitter from Lascells utilizes a Schottky diode oscillator module feeding a tuned waveguide and horn to give a directional microwave beam. The beam is modulated with a variable frequency audio signal which can be adjusted by the control on the top panel. Power is from a mains plug-top unit (supplied).

This Lascells Microwave Receiver uses a plate antenna which gives high sensitivity over a broad area. Output is to an internal loudspeaker and power is derived from a mains plug-top unit (supplied). A control allows the user to adjust the sensitivity to cater for different circumstances and distances.

This Lascells Microwave Probe Receiver gives a localised, precision receiver which finds particular application in identifying areas of peak and low amplitude in interference, reflection and refraction experiments. There are two controls, one for sensitivity and the other for volume of output to the internal loudspeaker. Power is from a mains plug-top unit. Output can be monitored by a CRO connected to the 4 mm sockets for quantitative measurements.
