Germicidal lamps are clear with special UV transmitting glass. For use in sterilizers and air and water purifiers. This is an ultraviolet C (253.7 nm wavelength) bulb for use in sterilization, water and air purification and surface disinfection. Used in the Forming and Disinfection of Contact Lenses. Used in UV Sterilizers for Fish Aquariums and Ponds. Fixed wavelength spectrophotometer detector. Germicidal lamps allow 253.7nm UV-C radiation from the mercury discharge to pass through the glass thus penetrating and inactivating the DNA of most micro-organisms.
