NMR sample tube caps fit tightly on the tube and provide adequate closure for many applications. To avoid cracking the tube, the cap should be eased off without twisting. Since these caps are disposable, they may be easily cut off. Long-term exposure to certain solvents may cause discoloration of the cap and leaching of plasticizers. EVA=Ethylene Vinyl Acetate
