Test tubes

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.
