Glass Wool

Wool plugs are often used in GC inlet liners to improve sample vaporization, and/or to keep non-volatile material from entering the column. They can also be used in packed GC columns, solvent desorption tubes, thermal desorption tubes, and purge traps to retain packed beds.

• Pesticide Grade (Silanized) for applications that involve active analytes, such as organochlorine and/or organophosphorous pesticides
• Silanized for general purpose use
• Phosphoric Acid Treated for acidic compounds such as barbiturates, free fatty acids, etc.
• Non-Treated for special application where the user deactivates based on their intended analytes

Our puller/inserter tool was specifically designed to assist in inserting/removing plugs to/from narrow bore tubing.
