  • Device and method for photoactivation
    Patent number: 6461567
    Abstract: A device comprising a light source, a sample holder and a temperature control chamber. The sample holder supports the vessels in a fixed relationship relative to the light source. The temperature control chamber surrounds the sample holder and vessels, so that a temperature control fluid may be passed around the sample vessels effectively maintaining the temperature of the sample vessels within a desired temperature range.
