Product name: Paramagnetic natural quartz EPR tube
Description: Compared with other brands, Norell EPR tube with a lower background signal and less prone to breakage. We use a special annealing process to reduce background noise while enhancing the ability of the tube against breakage. At the same time, we designed a new Teflon seal system attached to the side of treatment by baking the tube mouth, can effectively prevent the sample loss during temperature changing. Two types of tubes- standard and high precision- are available for you, while also providing tapered Teflon cap.
