Glass melting - Import export

The distinctiveness of these capillaries is their very thin wall-thickness in relation to their diameter. The extremely thin walls lead to the special feature of these capillaries to be deformed easily. Additional features linked to the thin wall-thickness are minimal optical distortion as well as very low absorption for a wide range of radiation. This feature is used e.g. for the construction of optical measuring cells. Materials Soda-lime glass (AR, I860, PH360 etc.) Gamma sterilized soda-lime glass Borosilicate glass (DURAN©, PYREX©, SIMAX© etc.) Neutral glass (FIOLAX© and DUROBAX©) Aluminum silicate glass (Schott 8252/8253) Quartz glass (naturally melted quartz glass and synthetically produced quartz glass, incl. F300) Lead glass (lead content up to 28%) Sealing glasses for various metals such as: kovar, molybdenum, steel, silver, platinum, palladium Process of Production Like most of our capillaries the ultrathin capillaries are manufactured using the redrawing method....

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
