Abstract: A method and system for reusing reaction vessels in a biotechnical processing apparatus. The system has a frame, an array of reaction vessels, an automatic actuator, and a decontamination system. The frame has at least one processing station. The array of reaction vessels is mounted to the frame for effecting biotechnical processing at the precessing station. The automatic actuator is connected to the frame and the reaction vessels for dispersion of solution in and out of the reaction vessels. The decontamination system is constructed in the frame for being accessed by the actuator to decontaminate the reaction vessels. The decontamination system includes a wash section, a heating section, a supply of wash fluid, a supply of acid solution and a supply of base solution. The actuator is programmed to access the decontamination section to subject the access the decontamination section, a bas solution and a wash reagent for decontamination the reaction vessels.
