Sealed stoppers - Import export

Novelis’ fracture-proof, seamless aluminum bottles offer needed protection when transporting and storing sensitive and critical goods. Novelis produces aluminum bottles for a range of applications — from commercial use to United Nations-approved packaging — in several coating configurations and sizes with fill capacities ranging from 38 ml to 6250 ml. These bottles include rolled thread for screw stoppers, tamper-proof seal and screw closure, plastic screw closure and locking ring, plastic threaded ring for pilfer-proof closure and flex-spout closure system.

We supply suitable tubes for storing and handling small samples. Microanalysis tubes have rounded bottoms and are fitted with an intermediate partition. The shaped rim ensures optimum sealing with a suitable stopper plug, which we can also supply. As an alternative to the stopper plug seat, the tubes can be made with a flanged rim. The intermediate partition in the upper part of the tube seals off the actual sample chamber, so that the chamber volume is very small. Nonetheless, the tube's long base body ensures convenient handling. Our microanalysis tubes are available in clear glass as well as amber glass for light-sensitive samples. The tubes are made of high-quality soda glass with diameters of 5...7 mm and a convenient length of 80 mm.
