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.

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....

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. Materials Soda-lime glass (AR, I860, PH360 etc.) Borosilicate glass (DURAN©, PYREX©, SIMAX© etc.) Aluminium silicate glass (Schott 8252/8253) Lead glass (lead content up to 28%) Process of Production The capillaries are manufactured by our in-house developed and patented production process.

The main feature of these new capillaries are the four separate chambers in a circular cross-section. The chambers inside the capillary are separated by an extremely thin membrane, which retains its shape also while the tube is being drawn to a fine tip. This makes them ideally suited for liquid perfusion applications with cells, because deformation of the cell walls and the membrane is reduced to a minimum. Theta cross-section capillaries

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...

A sensor only is not a responsible for good measurement. Often it depends on the surrounding conditions. Thick-walled glass-capillary-sections serve for the sensor as solid basis. Fitted on top, the sensor is mostly islolated from thermal and other environmental impacts. Solid connections between glass and metal For the production of glass-feed-throughs or glass metal sealings, precise cuttings of capillary-tubes are needed. These special tubes are glasses, which are adjusted to the physical parameters of the metals. We draw and cut such capillaries precisely to final size. Thereby the glasses can be fused on the customers wires and pins, which are made of metal. Scatter discs for the endoscopy Glass rings in different sizes with two satin cut sides, allow to manufacture small ring lightings for example for the endoscopy. By means of the rough surfaces of the glass rings, the light, coupled on the back, is refracted and diffusely spread. Different diameters and thicknesses as...

As a German producer of NMR tubes and NMR consumables such as pipettes and filling needles, Hilgenberg GmbH maintains close contact with the development departments of all major European NMR equipment manufacturers. We have no problems to meet the requirements of the new 100 mm NMR tubes for the Bruker Match™ system, and we are able supply high-quality tubes reliably for a reasonable price. Moreover, we also develop our own products, such as filling needles for the Bruker Match™ system, which have been optimized in close cooperation with external scientific and application experts. Standard NMR tubes of borosilicate glass 3.3 Our standard NMR tubes are manufactured of high-grade borosilicate glass 3.3 with a fine flame burnished rim and a lense-shaped bottom. The standard tolerances correspond to the usual values. If necessary, these tubes can be processed by a glassblower, as the glass used for the tubes can be fused easily with conventional laboratory glass. The tubes are...
