Abstract

Eine Vorrichtung zu Detektion von Kohlendioxid ist durch die Kombination folgender Merkmale gekennzeichnet : - eine Einlassöffunung (1) zur Aufnahme von Kohlendioxid in das Innere (4) der Vorrichtung, welche Öffnung (1) für Flüssigkeiten undurchlässig, aber für Kohlendioxid durchlässig ist, und ein Mittel zum Nachweis von Kohlendioxid, welches Mittel sich im Inneren (4) der Vorrichtung befindet. Diese Vorrichtung ist insbesondere bei der Sterilitätsprüfung flüssiger Medien einsetzbar, wobei die Integrität des dafür eingesetzten Systems erhalten bleibt und eine Verwendung in Verbindung mit handelsüblichen Filtrationseinheiten möglich ist .
