Problems solved by technology

[0005] While light or UV radiation in the "short wave" or UV-C wavelength range from LEDs, which are known to be effective in killing germs due to their ability to destroy nucleic acids in microorganisms, has therefore been recommended as the preferred option in such water purification reactors. light sources, however, the principles described so far are not suitable for practice, as they are not efficient enough and do not take thermal aspects into account
In this connection, the negative impact of heat on LEDs must be considered, since overheating of LEDs will reduce the light output momentarily, and a shift in wavelength towards the visible spectrum will significantly reduce the effective lifetime of the LED in the long run

Embodiment Construction

[0028] exist figure 1A first embodiment of the invention is shown in , which can be generally identified as an end cap purge reactor and more specifically a "single end cap reactor". In this type of reactor, the UV light source 7A is integrated in only one of the axial end caps 2A, 2B, which is attached to the opposite axial end of the main cylinder 1A so as to close its opposite axial end opening . The end cap 2A containing the UV light source 7A is isolated from the inner volume 4 of the master cylinder 1A by a UV transparent material in the form of a window 5, preferably made of quartz or silica glass. The end cap 2A further comprises a heat sink in the form of an annular segment 6 with surface area increasing features on its outer circumference, like fins 6a, promoting conduction and natural convection with ambient air. At the ring segment 6 a PCB 8 is attached, preferably one with a metal base improving heat transfer, for thermally conductive connection with the ring se...

Abstract

A biocidal purification reactor, including a main cylinder tube (1A;1B), at least one end cap (2A,2B,2C) closing at least one axial end opening of the main cylinder tube (1A;1B), at least two ports (3A,3B) communicating with the interior volume (4) of the main cylinder tube (1A;1B) in the vicinity of the respective axial ends of the cylinder tube (1A;1B), and at least one of said end caps (2A) or said main cylinder tube (1B) including a UV-light source (7A;7B).

Description

technical field [0001] The present invention relates to an in-line flow-through device for germicidal laboratory water purification applications based on UV light sources, as well as for other applications in chemistry (including analytical applications) and pharmaceutical applications. As such, the present invention relates in particular to a germicidal purification reactor, which is a self-supporting device or unit capable of being used to establish laboratory water purification applications. Background technique [0002] Purified water is used in laboratory environments for various purposes, namely for cell culture or in molecular biology, biochemistry or microbiology applications, but also in other fields like medical or healthcare. [0003] Germicidal purification reactors for such purposes are known in the art, but currently mercury UV lamps are mainly used as light sources because of their low cost and simplicity of use. A problem with all mercury-based light sources...
