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,...

For the specialized field of in-vitro fertilization (IVF), i.e. the insemination of an egg cell outside the body, we offer various solutions. These include ready-mounted capillaries that are glued into pipettes for easier handling, as well as capillaries with Luer connection for fitting to standard disposable syringes. In-vitro fertilization is used both human medicine and in veterinary medicine. The IVF capillaries are used to hold the egg cell or to separate it from the surrounding tissue. Capillaries with different diameters are available for this purpose. Micropipettes are used to inject sperm cells into the egg cell. Capillaries for InVitro-fertilization

Our highly versatile glass nozzles are also suitable for high-pressure applications. Because glass nozzles are simply large micropipettes, they have similar characteristics. Their flexible design enables them to be adapted to practically every application. For example, nozzles with very short or very long tips with a uniform internal channel can be manufactured. Similarly, the nozzle diameter is freely selectable. The workpiece holders for shaping the tips range from 1,5 mm up to 10 mm. Good connections ... The nozzles can be adapted in various ways. Apart from standard plastic Luer connectors for outlet diameters between 1 and 2 mm, sealing beads for Swagelok couplings or customer-specific sealing systems can be provided. Very small nozzles can also be supplied with closed tip to prevent the fine opening from being contaminated. Application areas Whether for Mixing, atomizing, spraying, metering liquid and powdery substances and samples or for the drawing of fine metal...

A specialized product that was developed for installing ignition elements and insulating them from the environment. Expansion of the inner diameter is also possible with longer components. For embedding other components, special gas and water-proof adhesives are available, which also retain their properties at high temperatures.
