Spectrum Tube Power Supply / Power Pack – 220 V AC (Safety Door, Improved Design)

This Spectrum Tube Power Supply is a newly improved, laboratory‑grade power pack designed specifically for safely operating 26 cm spectrum tubes in school and college science laboratories. The upgraded design now includes a Safety Door, ensuring that users cannot touch the electrodes while the tube is energised — significantly enhancing classroom safety during spectroscopy demonstrations.

A specially engineered internal holder secures the spectrum tube firmly in place, while the soft spring‑action contacts protect fragile glass tubes from breakage during insertion and removal. The matte black background panel behind the tube eliminates reflections and ambient light interference, allowing students to observe emission lines with improved clarity and contrast.

This power pack operates on 220 V AC and is fully CE, CSA, and CUS approved, ensuring compliance with international electrical and safety standards.
