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 ¥ìm 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 can also be adapted to suit individual customer requirements.
