Standard caps - Import export

We manufacture various sizes of small glasses for a wide range of applications. They are mostly made of high-grade neutral glass (clear or amber), with soda glass as an alternative. The bottle necks can be made with a flanged rim for sealing with aluminium crimp caps as well as plastic or rubber septa. Threaded necks for most standard threaded caps are also possible. Our standard bottle volumes are 2 ml and 4 ml.

Our new NMR septum caps for standard 5 mm NMR tubes are made of EVA and have a special sealing septum inside the cap. This septum ensures significantly better sealing than standard NMR caps, for example with regard to chloroform or other solvents. A special evaporation test conducted by Bruker Biospin confirmed the extraordinary tightness of the caps. The caps can be punctured with conventional needles, and are also suitable for automated applications. NMR-septum-caps
