Norell Suprasil EPR tubes are recommended for UV catalyzed reactions in the region at and above 190 nm (90% T @ 190 nm). They provide greater reduction of background noise than natural quartz and are used primarily in studies where greater signal sensitivity is needed. Suprasil EPR tubes are also useful for Boron NMR (<0.01 ppm Boron) spectroscopy.
