We offer a large assortment of ATR-crystals for use in the field of spectroscopy. We also offer both dismantleable and sealed cuvettes. For decades, cuvettes have been used for the optical analysis of liquids, oils and pastes. Cuvettes consist of a metal frame and two crystal windows (sometimes Fused Silica windows). The substance to be measured is held between the two windows. To prevent any leakage all lead seals are covered with an amalgamating solution. Where the substance to be measured is viscous, seals made of Teflon are sufficient. The thickness of the substance to be measured is adjusted using a spacer. We can construct the cuvettes in house to your specification or supply the parts, allowing you to assemble the cuvettes using the following Instructions. 用于液体和固体分析的测量单元和替换部件 我们提供用于光谱学领域的大量ATR晶体。 我们还提供可拆卸和密封的反应杯。几十年来，试管一直被用于液体、油和糊剂的光学分析。反应杯由一个金属框架和两个水晶窗（有时是熔融石英窗）组成。待测物质夹在两个窗口之间。为了防止任何泄漏，所有铅密封件都用汞合金溶液覆盖。如果要测量的物质是粘性的，聚四氟乙烯制成的密封件就足够了。使用垫片调整待测物质的厚度。 我们可以根据您的规格建造反应杯或提供零件，允许您按照以下说明组装反应杯。
