Since the 1950s we have been producing glass capillaries in utmost perfection for a wide range of applications. In the past decades our expertise as well as the variety of our products have been growing continuously. Apart from standard dimensions we also produce numerous special sizes – even in small quantities. Our modern production technology enables us to realize customer requirements at short notice. The high-precision measuring equipment ensures compliance with tight tolerances.
We use a wide range of glass types for the production of our capillaries. We obtain them from well-known, large manufacturers as well as from small manufacturers of special glasses whose careful manufacturing processes guarantee a high product quality. For some applications we use glasses from specialized suppliers who can manufacture glasses is small quantities and on a laboratory scale.
The materials we use include the following glass types:
The largest part of our capillaries is produced with the redrawing method. During this process blanks (or so-called performs) are heated and drawn until they have reached the desired measure. The process is highly flexible and allows the production of prototypes or even large quantities on the same plants and under the same conditions. In addition to the redrawing method, some thick-walled capillaries may be directly drawn from the melt. In this process, however, there are limits to the precision and dimensions of the capillaries.
Apart from the production of capillaries, their processing is also one of our particular strengths. We utilize this strength for your individual requirements!
We offer various possibilities for further processing:
We manufacture capillaries with an outside diameter of 0,05-10 mm and offer various wall thicknesses and inner diameters. With smaller diameters we are able to realize wall thicknesses as narrow as 10 μm (0,01 mm). In order to ensure a good handling, the smallest possible inner diameter ranges at 4- 5 μm at a wall thickness of 10-20 μm. Our standard manufacturing lengths are 1060 and 1500 mm. Our flexible production enables us to produce lengths and blanks in the range of 1-3000 mm, according to customer requirements. Small capillaries with a diameter up to 0,25mm can even be processed to lengths greater than 3000 mm.
In addition to the standard geometry of a simple round profile with various wall thicknesses, we offer special geometries such as flat, square and triangle capillaries. Here, you can find an overview of possible geometries and geometries that have already been produced, here. These represent a rough overview of the possible geometries that he have already manufactured using our 14.000 different configurations.
Our capillaries are used by a large number of different industries and applications. Their application is not always as obvious as their use as micropipettes or test tubes for NMR-measurements. The capillaries are often installed in electronic components or used as a single piece in formative processes.
