NORELL® EPR tubes produce lower background signals and have better resistance to breakage than competitor brands. Our proprietary technical treatment process reduces background noise along with the benefit of protecting against tube breakage. Additionally, we have designed a new fluoropolymer closure system around our fire-polished tube ends that prevents sample loss during temperature gradients. Available in both standard and ultra precision. Supplied with tapered fluoropolymer caps.
