The major difference between our standard capillaries and conical capillaries lies in the different opening diameters on both ends. Whereas standard capillaries are manufactured with the redrawing-method conical capillaries are produced in a discontinuous process. 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) Lead glass (lead content up to 28%) Sealing glasses for various metals such as: kovar, molybdenum, steel, silver, platinum, palladium Process of Production During the production process of the conical capillaries a straight tube or capillary is heated and drawn. By drawing the capillary a pointy conical, tapered form, a so-called double-tip, is formed. The tip can be parted in the capillary’s smallest diameter and results in a larger diameter on one side which is determined by the blank used in the process, as...
