Ultraviolet Cabinet

Ultraviolet Cabinet offers a fast, efficient and reliable solution to disinfect any devices and types of equipment from numerous vegetative organisms and viruses without the obligation for heat or chemical substances. Generally, UV cabinets are used for Chromatographic analysis by Ultraviolet Fluorescence. These cabinets are useful for observing Chromatogram by combining both short and long wave Ultraviolet Lights as well as White Light.

UV light is effectively utilized in the cabinets, powerful UV tube lights are combined with carefully located optical reflectors to ensure uniform intensity distribution of the UV radiation throughout the cabinet. Acrylic windows offer exceptionally clear all-round vision and do not allow transmission of UV. Cabinet has flap front access as standard for easy access to the interior of the cabinet. Two service ports with covers are supplied in the side panels. The cabinet is supplied with handy corner shelves. 15 W white lights, operated from an external switch, illuminate cabinet interior. The Control system allows the choice of time of the UV exposure from 5 to 30 minutes. The base tray is black which highlights spillages.

The Cabinets also act as an efficient shield against beta radioactive emissions and can therefore be safely used with Isotopes, such as P 32. The Cabinet’s White Light provides excellent visibility when working inside them. And this Polypropylene Cabinet resists cracking and discolouration under extended exposure to UV light, as well as acids and other chemicals. The fan/filter module provides a continuous wash of HEPA filtered air to remove contaminants.


It is environmentally friendly. This is because it does not emit any by-products such as sodium into the environment. Therefore, there are no chemicals handled. The UV system is also very cost-effective. The process also destroys every microorganism that is in the material. The method is only suitable when microorganisms needed to be destroyed but not as a form of water softening. It should be considered because it is only able to kill microorganisms but not remove minerals.


  • Long wave (Ultraviolet) component; Fluorescing spots on chromatograms can locate compounds like dyes, vanillin’s flavones, alkaloids etc.
  • Short wave (Ultraviolet) component; Detects Compounds, such as Barbiturates, Purine and Pyrimidine derivatives, PHT-Amino Acids, DNP -Amino Acids and Steroids.
  • Denature Nucleic Acids in 5 to 30 minutes making them unsuitable for amplification and contamination of PCR reactions, viral and bacterial cells.
  • In the detection of traces of minerals and study of old inspections.


  • The potential health hazards arise from UV Rays with wavelengths greater than 180 nm. UV Rays of shorter wavelength is strongly absorbed in air.
  • In Skins, excessive short term exposure causes sunburn and can result in an increased risk of skin cancer.
  • In the Eyes, exposure can cause acute damage to the cornea and conjunctiva causing pain, light sensitivity and tearing.
  • Staff working with UV Rays sources must be provided with adequate information, instruction and training in its safe use.
  • Hands must be protected by wearing gloves with low UV transmission. Nitrile/ latex gloves are suitable.
