  • Method for irradiating cells
    Patent number: 5433738
    Abstract: An apparatus for irradiating cells with ultraviolet light including an ultraviolet light source and an outer cylinder that surrounds the ultraviolet light source. Hollow tubing is helically wrapped around the outer peripheral surface of the outer cylinder. The hollow tubing is adapted to transport suspended cells over the outer surface of the outer cylinder so that the cells can be irradiated by the ultraviolet light source. An inner cylinder can be positioned inside the outer cylinder, between the ultraviolet light source and the outer cylinder. The apparatus can include an arrangement for ventilating the apparatus during use in order to maintain a substantially constant temperature.
