Available in 5 mm and 10 mm outer diameters, these tubes feature significantly reduced wall thicknesses compared to traditional options. The 5 mm tubes have a 0.29 mm wall, down from the Standard Series 0.43 mm, while the 10 mm tubes slim down to 0.42 mm from 0.59 mm. This reduction in wall thickness translates to a larger sample volume, allowing for enhanced signal-to-noise ratios and improved sensitivity in your NMR experiments. The sample volume within the RF coil for the 5mm tube is approximately 151 µL and the 10 mm is approximately 654 µL assuming a 25 mm active height. Both 5 mm and 10 mm Ultra-Thin wall series tubes increase sample volume approximately 10%.
