PTFE Tube Liners & 29Si NMR
PTFE-FEP NMR Tube Liners for Corrosive Samples & 29Si NMR
For NMR investigations where chemical compounds such as hydrofluoric acid, ammonium bifluoride and concentrated hydroxide solutions are present, Wilmad’s PTFE-FEP NMR Tube Liner provides a contamination-free environment.
PTFE-FEP Tube liners are round-bottom and made from Polytetrafluoroethylene/ Fluorinated Ethylene Polypropylene Copolymer. Thin-wall construction minimizes filling-factor losses. Although the liners are not rigid, they straighten upon insertion into the sample tube. Not recommended for elevated temperature studies. A PTFE plug is included with each liner.

PTFE-FEP NMR Tube Kit for 29Si NMR
Wilmad’s PTFE NMR Tube Kit features a high field 500MHz precision bore open-ended glass adapter for a 5mm spinner turbine. Please use a depth gauge to fine adjust the position of the liner so no glass part will protrude into the Rf coil limit.
Note: The PTFE tube used in this kit is not interchangeable with PTFE liner (P/N 6005).
