SafetyBarb™ Glassware - Sigma-Aldrich Glassware Catalog


This new glassware features SafetyBarb™ removable connections for 1/4 in. i.d. flexible tubing. The "barbed" polypropylene connector grips tubing firmly and can be safely detached from the glassware by unscrewing the PBT cap. Accidental glassware breakage is eliminated when installing or removing the tubing. A silicone rubber seal ensures a liquid- and vacuum-tight connection to the glass GL 14 thread.
