摘要

Process challenge device (2), especially for simulating the worst-case penetration conditions of a load inside a sterilization chamber, comprising a detector volume (90) for housing a biological, chemical or physical indicator (140), whereby said detector volume (90) is arranged at a dead end of a series of gas volumes (110, 14, 118), whereby said process challenge device (2) comprises two parts (6, 14), namely a housing part (6) and an insertion part (14), whereby said insertion part (14) is at least partially insertable into said housing part (6) in such a way that said detector volume (90) is arranged without any seal inside said both parts (6, 14).
