Markes PTFE Tube Inserts
PTFE Tube Inserts
If direct desorption in an empty tube could cause irreversible contamination of that tube, its best to place the sample in a disposable tube liner. Markes’ direct desorption liners are made from PTFE and designed for use with stainless steel tubes. They protect the tube walls and simplify sample weighing. Two types of liners are available:
- Snug-fit liners, which should be used for most powdered/granular samples.
- Loose-fit liners, suitable for semi-solid samples (which should be smeared around the inside of the liner).
