Description
These quality ‘Geissler type’ gas discharge spectrum tubes have an electrode at each end with a fine capillary tube in the middle which effectively demonstrates the spectral lines of pure substances with a colour discharge.
Use intermittently and do not use as a lamp source.
We also offer a power supply specifically for powering these tubes, refer to POWER SUPPLY & SPECTRUM TUBE, cat. IEC1813 listing.
Another suitable power supply to run these tubes is an induction coil with 75 mm spark (voltage required approx. 30Kv.), refer to HIGH VOLTAGE SOURCE KIT, cat. SWB0181/E listing.
