A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.
Standard models from this range are also listed in our online store, priced in USD — see the price yourself ↗
The exhibit the phenomenon of surface discharge, allowing visitors to utilize their existing knowledge and explore the mysteries behind the phenomenon through careful thinking and analysis.
The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
Composed of a glass tube and two electrodes, fixed on a base, the flat and smooth glass tube wall is equipped with a circular electrical level on both sides, with one level connected to high voltage and the other level connected to ground. After the high-voltage power supply is turned on, visitors can see a very interesting discharge phenomenon on the surface of the glass tube.
Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
Other models from the Basic Science line, all held to the same specification and the same control package.

Rotate two polarising filters and watch colours appear and vanish.

Sand on a driven plate jumps into nodal figures as the frequency changes.

Coloured discs drain to grey as the spin speed passes the eye's limit.

Gas discharge tubes and a slit spectroscope show emission lines directly.
Attach a theme outline, a floor plan, or nothing at all — a photo of the space is enough to start. Quotations are issued against a real exhibit list, not per-square-metre guesses.
