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.

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...

Our systematic research into new processing methods enables us to improve our production processes and the manufacturing of new products. In this way we are able to realize e.g. extremely thin-walled capillaries with two parallel surfaces. In this process the production of various widths and heights are possible. The innovative manufacturing procedure permits us to produce wall thicknesses of less than 150 μm. Thanks to the minimal wall thickness and parallel sides these capillaries are perfect for high-precision measurements, because the measurement signals are hardly disturbed or absorbed. Therefore, these capillaries are ideally suited for the use as measuring cuvettes and flow cells.

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.

The cross-sections of multi-channel capillaries consist of a large number of single holes, which are either in a random order or neatly arranged. Depending on the application in which these capillaries are used they can fulfill several tasks. Materials Soda-lime glass (AR, I860, PH360 etc.) Borosilicate glass (DURAN©, PYREX©, SIMAX© etc.) Aluminum silicate glass (Schott 8252/8253) Process of Production Two different production methods are used to manufacture multi-channel capillaries: 1. Production from a preform Prior to drawing the capillary several performs are mounted and joined together. During this process the channels are created from a single capillary. Hollow spaces are then filled with glass rods and are evacuated with heat. All unintended side channels and hollow spaces between the capillaries are sealed during this process and result in a closed cross-section, which is only punctuated with the inner geometry of the single capillaries. Reproducible profile sizes,...
