Special tube shapes - Import export

We offer a wide range of tubes for the automatic or manual determination of the melting or boiling points of liquids and solids. For this, the samples are heated slowly in the test tube until they reach their melting or boiling point. Depending on the application and the temperature range, we use the following types of glass for our melting and boiling point tubes: Soda glass (standard) Borosilicate glass Quartz glass Optional end shapes: open at both ends one end closed both ends closed curved Dimensions: Length 50-300 mm Outer diameter 0,6-2 mm Inner diameter 0,3-1,6 mm U-tubes for determining the melting point Apart from the standard melting point tubes, we also manufacture special U-shaped tubes of soda glass. Hereby, the two legs of the U-tube have different lengths. As an additional option, the U-tubes can be fitted with a small funnel on one or both legs. Melting-& boiling point determination tubes
