Product Details
The PTFE ferrules are available in sizes of 1/16'', 1/8", and 1/4", with an upper temperature limit of 250°C. They feature precision-drilled IDs to eliminate mold imperfections and a one-piece design that does not require a back ferrule. The PTFE material is completely inert and does not adhere to glass. Each size is sold in standard 10 piece packages, with specific compatibility: 0.3mm ID ferrules fit 0.18mm ID and narrower capillary columns, 0.4mm ID ferrules fit 0.25mm ID capillary columns, 0.5mm ID ferrules fit 0.32mm ID capillary columns, and 0.8mm ID ferrules fit 0.53mm ID capillary columns. The "straight" ferrules are specifically designed for use with 1/16" OD tubing.
