Abstract
A device for mixing two paste components, such as a dental impression substance and a catalyst, comprising a tubular housing, two inlet openings for the two paste components to be mixed, and an outlet opening for delivering the mixed paste, is presented. The housing consists of a premixing chamber at the front end and a tubular mixing chamber at the rear end. The two paste components are mixed first in the premixing chamber by a dynamic rotor and then mixed in the tubular mixing chamber by a twisted static shaft, resulting in a well mixed, bubble-free paste at the outlet opening of the housing.
