This sterilisation box, as the name suggests, mainly plays the role of sterilisation and disinfection. It can also be known as a low intensity UV lamp. It uses low mercury vapor pressure (<10-2Pa) to be stimulated to emit ultraviolet light, and its emission spectrum has two main lines: one is 253.7nm wavelength and the other is 185nm wavelength, both of which are invisible to the naked eye. 

The spectrum with a wavelength of 253.7nm plays a bactericidal effect. The main principle of sterilisation is based on the law of the absorption line of cells to light waves: cells absorb the largest amount of ultraviolet light between 250-270nm. Once absorbed the ultraviolet light can act on the genetic material (DNA) of the cell to make it act photochemically. The energy of the ultraviolet photons is absorbed by the base pairs in the DNA, causing the genetic material to mutate, causing the bacteria to die immediately or fail to reproduce offspring to achieve the purpose of sterilisation.

It is claimed to kill up to 99% of bacteria and viruses.

Always use with the lid closed and never open mid cycle. The light might seem low in brightness but please remember the part that is killing the bacteria / virus is invisible to the human eye. Always unplug the device from the electrical supply when not in use.
