Abstract
An apparatus (1) for irradiating material comprises a single UV, pulsed brigth white light or IR lamp (2) with a centrally disposed receptacle (3) for containing material to be irradiated. The lamp can be an elongate hollow tube (2) of annular construction. Internal formations may be present within the lamp to control the position of the arc. For example, the lamp may have a plurality of longitudinal segments arranged such that a discharge arc is formed within each segment or internal formations may be provided to direct the position of the arc within the lamp. A pump (36) may be included for moving material through the receptacle which is preferably the hollow area within the annulus of the elongate hollow tube. Material can be treated batchwise or in a continuous process. This apparatus is suitable for the sterilisation of biological and/or non-biological materials. A further use is in carrying out photolysis on chemical substances in photochemical reactions.
