Use to Excite Spectrum Tubes As you conveniently mount the spectrum tubes into the spring-loaded holders and energize them, a specially designed shield holds the tube firmly while preventing you from touching the electrodes.
A black metal panel behind the tube eliminates distracting ambient light and protects the tube from breakage.
