NMR septum caps

Compared to standard caps, our NMR sealing caps provide far better sealing protection against solvents such as acetone, water, chloroform and DSMO. The septum seal attached to the rim provides additional protection here. And yet the caps can be removed from the tubes without any hassle. When removing and filling samples, the septum can also be pierced through with normal disposable cannulas. The caps are then only slightly less impermeable and even allow for the tubes to be emptied and filled with low evaporation loss.

NMR-labels for standard 5 mm tubes

These labels are solvent-resistant and, due to their durability, are ideal for clear, long-term identification of samples in 5 mm NMR tubes. Since they are arranged on a sheet, they can be printed using a laser printer or conveniently written on by hand. Labelling field size 25 x 13 mm, total length 37 mm.
