Abstract

A retractable assembly, comprising: a housing; a media connection with complementary connecting means; an immersion tube; and a probe provided in the immersion tube. The probe has a probe head on its end facing the medium, wherein, in the service position, the probe head is arranged within a treatment chamber formed in the housing, wherein the immersion tube is divided into three regions, and, indeed, a upper region facing away from the containment, a middle region, on which a sealing system is provided, and a lower region facing the containment, wherein the sealing system is so embodied that in no position of the immersion tube does an exchange of medium or impurities from the drive to the treatment chamber, or vice versa, occur.
