Our new NMR caps offer an increased denseness to solvents, such as acetone, water, chloroform, and DSMO, compared with standard caps. The septum, which is an additional seal on the rim, further increases the tightness. Nevertheless, the caps can be removed from the tube easily. When extracting and filling the samples, the septum is suitable for puncturing the cap with regular disposable cannulas. The caps will only loose minimal tightness, which ensures low evaporation when emptying and filling the tubes.
