PTFE-FEP NMR tube liner provides a contamination-free environment.

• Ideal for samples where hydrofluoric acid, ammonium bifluoride and concentrated hydroxide solutions are present
• Thin-wall construction minimizes filling-factor losses
• PTFE plug is included with each liner

PTFE-FEP Tube liners are round-bottom and made from polytetrafluoroethylene/fluorinated ethylene polypropylene copolymer. Although the liners are not rigid, they straighten upon insertion into the sample tube. Not recommended for elevated temperature studies.
