CHEM-FLEX™ Transfer Lines
 Especially suited for transfer of products packed in Aldrich Sure/Seal™ bottles. These ready-to-use transfer lines incorporate CHEM-FLEX™ 106 tubing, which has a chemically inert, thin-wall PTFE inner tube sheathed in clear PVC for extra strong, flexible lines that are resistant to crushing or kinking. Two 12 gauge SS needles (6 and 18in.) are connected to the CHEM-FLEX™ 106 tubing with nylon clamps. Liquids contact only PTFE and SS during transfers.

Serrated Rubber or Silicone Septa
 Closure has a turnover flange molded to grip outside of container neck, promoting a double seal in conjunction with annular serrations on a hollow plug. Annular serrations depress themselves against the inside wall of the bottle neck, making each serration a suction sealing point.
Silicone Serrated Septa (shown above) are excellent for high-heat and sterile applications.
