4 Once the room's blinds have been closed and the lights turned off, turn on your ultraviolet lamp
Manufacturers are capitalizing on consumer health concerns by adding germ- and bacteria-killing ultraviolet lamps
to their air purifiers.
The invisible ink can only be seen under an ultraviolet lamp
, where it fluoresces to a bright red color.
Once the droplet assumes the desired form, a few minutes under an ultraviolet lamp
polymerizes the liquid into a hard lens.
Features include a hologram that does not refract light if replicated and an ultraviolet ink design that, while invisible to the human eye, can be checked with an ultraviolet lamp
. If the certificate is photocopied a heat-sensitive spot vanishes and the word ``Copy'' appears.
These samples were divided into four quadrants, placed in an aluminum-lined boxed with an ultraviolet lamp
, and each quadrant was given increased exposure (0 hrs., 12.8 hrs., 25.5 hrs., and 38.3 hrs.) to ultraviolet light.
Other components, such as an ultraviolet lamp
, help ensure water purity when used properly.
The GloGerm basic germ detective kit contains a bottle of fluorescing oil, a bottle of fluorescent powder, and a safe, low-power ultraviolet lamp
. The oil and powder contain a plastic fluorescing compound that is easily seen under ultraviolet light.
The self-contained unit will ozonate more than 6000 gallons of water daily using oxygen and ozone generators, and an inline ultraviolet lamp
. A protein-derived enzyme is added to the water during processing, which rapidly decomposes ozonated water into water and oxygen, thus reducing numbers of microbes without the use of preservatives.
The [Beta]-glucuronidase hydrolyzes 4-methylumbelliferone glucuronide to the fluorescent umbelliferone, which is easily observed with a ultraviolet lamp
. This test has also been widely verified.
Other new and expanded areas include space air diffusion data, equipment heat load data, combustion turbines, and ultraviolet lamp
