Abstract

A sample collector is provided for receiving a breath gas sample and a gas sample testing device is provided with such a sample collector. The sample collector is configured for receiving from a person a breath gas sample to be investigated. The sample collector includes an inflow part (2) with an inflow opening (IO) and an outflow part (13) with an outflow opening (OO). The sample collector provides a flow duct guiding a gas sample from the inflow opening (IO) to the outflow opening (OO). The inflow part (2) is rigidly connected with the outflow part (13). The inflow part (2) and the outflow part (13) together form a housing which gas-tightly surrounds the flow duct. The inflow part (2) tapers in a direction towards the outflow opening (OO). The outflow part (13) tapers in a direction towards the inflow opening (IO).
