Fine (0.7mm wide, 0.07mm thick), PTFE sealing rings for ground glass cones. In use the ring is carefully stretched onto the cone, becoming elastic and producing a tighter seal than conventional full sized sleeves (solvent leak rate: <0.2mg/day). Operating temperature range: -20 to +300°C. Supplied in packs of 50, mounted on an applicator tube.
