tube leak detection machine

We produce various tubes and glasses, e.g. for storing samples, tablets, and other sensitive materials that may not come into contact with plastic. The bottom ends of the tubes can be rounded or flat. Available glass types Soda glass (standard) Neutral glass Amber glass Borosilicate glass Standard diameters 17 mm (wall thickness 0,8 mm) 21 mm (wall thickness 0,8 mm) 28 mm (wall thickness 1,0 mm) Customized dimensions on request! Caps and closures Snap-on cap with slightly flanged rim (standard) Rubber stopper, with recessed edge on the tube Ribbed plug, without flange on the tube

Small tubes are required for handling and storing small quantities of samples. To comply with these requirements, we have adapted and extended our manufacturing capability. We are therefore now able to produce very short and very small sample tubes without problems. For example, tubes with 3 mm diameter, and a length of 20 mm.

We manufacture reagent and centrifuge tubes in standard sizes and also with special dimensions and versions from soda glass, borosilicate glass, neutral glass, and quartz glass – optionally with or without flanged rim. All our tubes have a flame burnished rim and can be supplied with a rounded, flat or pointed conical bottom. We are able to process tubes with diameters up to 40 mm, and lengths up to about 500 mm – also thick-walled tubes. Special reagent micro tubes We are able to manufacture reagent micro tubes with rounded bottoms, i.e. with very small dimensions. For example, soda glass tubes with rounded bottom, flame burnished rim, 3 mm diameter, and a length of 20 mm. Test tubes with notch for thermal processes These special test tubes were developed to enable ventilation of the tube’s interior during a thermal process. The notch prevents complete closure and thus an over pressure.

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

We supply suitable tubes for storing and handling small samples. Microanalysis tubes have rounded bottoms and are fitted with an intermediate partition. The shaped rim ensures optimum sealing with a suitable stopper plug, which we can also supply. As an alternative to the stopper plug seat, the tubes can be made with a flanged rim. The intermediate partition in the upper part of the tube seals off the actual sample chamber, so that the chamber volume is very small. Nonetheless, the tube's long base body ensures convenient handling. Our microanalysis tubes are available in clear glass as well as amber glass for light-sensitive samples. The tubes are made of high-quality soda glass with diameters of 5...7 mm and a convenient length of 80 mm.

Our sample tubes are used for X-ray fine structure analysis of single crystals, powder specimens, and liquid crystals. Based on the low absorption through the glass the extremely thin-walled capillaries allow the analysis of small samples sealed in a gas and moisture proof environment. According to the Debye-Scherrer method or in gerneral SAXS (small angle x-Ray scattering) and WAXS (wide angle x-Ray scattering) measurements can be made with our mark tubes, which are also named XRD capillaries. The wall thickness of only about 10 µm makes the tubes particularly suitable for high-precision measurements. Thanks to the wide funnel at the upper end, samples can be filled easily into tubes even with the smallest diameter. Absorption coefficients Our test tubes are manufactured of various types of glass with different linear absorption coefficients, so that a suitable tube can be found for practically every application. High quality standards are maintained during production, which...

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...

Fewer steps to the finished workpiece With t project you can see all the variables of the bending process before you start the production. Adapted to the material and collisionfree, it makes it possible to plan and execute complex bending geometries. The virtual bending simulation determines exact bending timings and cutting lengths; it also tests tube geometries in advance for feasibility. Tube data and bending results are documented with accuracy and they can then be replicated 100% . All the most common interfaces are available for the import and export of data and connection to BDE or ERP over the network.

We provide special rods and fibers, on whose tip a drop of the sample can be filled conveniently into a test tube. Fibers with a diameter of less than 0,1 mm can be inserted even into the smallest test tubes. These rods and fibers are mainly made of borosilicate glass 3.3. We can also supply rods and fibers that are made of the same type of glass as your test tubes.

We have developed special glass cannulas that greatly simplify filling our test tubes with liquid samples. Our thinnest cannula has a diameter of less than 0,1 mm. This enables even the finest test tubes to be filled without problems. A standard Luer connection enables the cannula to be fitted to conventional one-way syringes or microliter syringes. Our filling needles are made of borosilicate glass, whereby the shaft consists of plastic into which the needle is bonded. Various diameters are available.
