LOW PRESSURE MERCURY VAPOR LAMPS

Low pressure quartz UV lamps, also called "germicidal lamps", use UVC light to obtain the rapid sterilization of bacteria, molds, fungi, viruses and microorganisms in both air and water.
In this type of lamp about 40% of electrical energy is converted directly into UVC radiation with monochromatic emissions at 254 nm for germicidal applications and at 185 nm for surface oxidation.

LOW PRESSURE AMALGAM LAMPS, LINEAL MODELS 

Low-pressure amalgam UV lamps contain not only mercury but a solid amalgam or mercury alloy with other metals.
Low-amalgam lamps represent the optimum solution for the disinfection and ultraviolet oxidation of water, air and surfaces, since they combine very long life (up to 20,000 hours) and optimum UVC efficiency at 254 nm (up to 45%) at A much higher power density than traditional low pressure lamps and mercury medium pressure lamps.

Amalgam UV lamps, thanks to high power and long life, are an economically advantageous solution for ultraviolet disinfection systems since they contain significantly the operating costs derived from the decrease in the number of installed lamps, electronic components And maintenance costs.

A special quartz coating process allows UV lamps at low amalgam pressure to maintain virtually constant germicidal action throughout the lamp life cycle

LOW PRESSURE AMALGAM LAMPS, U-SHAPE, SPIRAL & OTHER FORM MODELS

Experience in the manufacture of UV lamps and quartz glass processing has led to the manufacture of compact low pressure mercury and amalgam lamps with non-linear shapes (HCL models) for applications where it is desired to maximize the germicidal power in Small spaces.
Here are some examples.

Varying shapes of low pressure amalgam lamps
HSSL amalgam lamps can be manufactured In different forms and models as shown in the attached figure. The 6 forms are available for a tube length of 1595mm with maximum diameters of 10 -12 -15 -19 -28 & 32 mm.

UV BLACKLIGHT LAMPS

Wood lamp (Named from the American scientist Robert Williams Wood) or black light, is meant as a light source that emits electromagnetic radiation prevalently in the range of ultraviolet and omissible, in the field of visible light.

Aplications
A Wood lamp produces light not directly visibile by the human eye, however it can be used to illuminate materials in which ultraviolet radiation induces fluorescence effects. Possible applications of these properties occur in the fight against counterfeiting of banknotes by the use of banknote control or in the search for cracks in metal structures coated with UV-reactive material.

Main features of black light amalgam UV lamps

UV-C short-wave (180 – 280 nm) with peak at 254 nm,  Suitable for chemical, photochemical and chromatographic applications, in microbiology are useful for the identification of bacteria and fungi, for the analysis of fluorescent materials and for the analysis of minerals.   UV-B Medium-wave (280 – 320 nm) with peak at 310 nm  Suitable for chromatographic and GEL analyzes, for subtle layer tests, DNA / RNA electrophoresis test tests and for mineral analyzes.on aptas para análisis cromatográficos y GEL, para tests en capas sutiles, para test de investigación de la electroforesis ADN / ARN y para los análisis de minerales. UV-A Long-wave ( 320 – 380 nm) with peak at 366 nm  Suitable for many organic applications, fluorescence tests, food industry, control of banknotes and documents, artistic restorations, in many Microbiology tests, in dermatological field or for skin diseases and for the care of favism or also for geological inspections.

STANDARD GERMICIDAL UV LAMPS

Standard Germicidal Lamps

Germicidal lamps provide a highly efficient source of UV light for medical and commercial applications. They are aviable in single-ended and double-ended formats with widely-used G10.2q, G5, G13, G23 and 2G11 bases.
