Odor impregnation connector

This connector can be used to join two jars to use them for impregnation. You can put your target odor in one glass and anything you want to impregnate in the other. This could be Getxent tubes, filter paper or anything you prefer. Fits on regular jars with a screw-on lid with a diamaeter of around 60 mm (German: DIN 55). Important: this connector does not fit on regular twist-off caps, only on caps with a thread! Recommendation: for obvious reasons, the connector is not 100% air tight. Use additional tape if needed.
