Abstract: A process challenge device for evaluation of contamination forming and removal processes inside of narrow and hollow channels comprising sample of at one sample, at least capsule having an inlet connector, a flow shaping element and an internal cavity for holding said sample, a lock—or end cap—for each capsule securing the sample inside the cavity characterized by said tag located in the capsule against one of the walls of the internal cavity that is shaped not to change the parameters of the fluid flow while it flows into said cavity and over the face of the sample simulating the flow through an equivalent narrow channel.

Abstract: A reprocessing apparatus for washing and cleaning a load comprising a reprocessing chamber, a buffer tank, a buffer tank valve and recirculation valve, fluid distribution devices and plurality of pumps, at least one ultrasonic transducer and a drainage system characterised by said buffer tank is supplied with fresh water and process chemical where buffer tank holds fresh process fluid that is pumped to at least one fluid distribution device and directly into the load, the drainage system for discharging process fluids and recirculation loop for pumping said fluid back the reprocessing chamber, and a method of reprocessing a load in a reprocessing apparatus characterised by that fresh water is mixed with process chemicals externally to said chamber in the buffer tank and delivered to said chamber through fluid distribution devices and internal connecting lines while simultaneously washing the load internally and externally and discharging the fluid from the reprocessing chamber.
