    摘要： A biocidal fluid purification cap (2) for a fluid container (1), preferably one storing purified water for use in laboratory environments and especially purified water for cell culture and water for molecular biology. The purification cap (2) includes a cap body (3) including an engagement feature (20) for removably attaching the cap body (3) to a mating engagement feature on a spout of the fluid container (1) to hermetically close a spout opening, at least one LED (7a) adapted to emit light in the UV-C range, electronic circuitry (15) for driving the LED(s) (7a), and a power supply for the electronic circuitry (15). The LED(s) (7a) is/are arranged in said cap body (3) so as to be separated from the environment by an UV-transparent window (6) provided in the cap body (3) such that light emitted from said LED(s) (7a) enters the opening of the spout when the cap (2) is attached to the spout of the container (1).

    摘要： The invention provides a water purification and dispensing system, preferably for producing ultrapure water and offering the purified water at dispensing sites. The system (100) comprises a first purification stage (1) for purifying water to a first water purity grade, a water recirculation loop (2) including a second purification stage (3) for purifying water to a second water purity grade higher than the first purity grade and a dispensing portion (5) for the purified water, and a reservoir (4) arranged to store the water purified at the first purification stage (1) through a first connecting flowpath (7a) and to deliver the stored water to the water recirculation loop (2) through a second connecting flowpath (7b). A 3-way valve (8) is provided in the flowpath between the first purification stage (1) and the reservoir (4) to selectively block the flow of purified water to the reservoir (4) and to drain the purified water from the first purification stage (1). A third connecting flowpath (15) is branched from said dispensing portion (5) and is connected to the first connecting flowpath (7a) upstream of an UV radiation treatment device (11).
