Quick answer: A Turnover Flange Septa is a rubber sealing disc with a turned-over flange edge, used to stopper and reseal test tubes, sample vials and similar glassware, often for repeated needle penetration in sampling work. Lab Glassware Manufacturer supplies them in four rubber/surface combinations — natural rubber or silicone rubber, each in serrated or non-serrated finish — across four sizes from 12mm to 25mm.

Choosing a Septa Material and Finish
Natural rubber is a cost-effective general-purpose choice; silicone rubber offers better chemical inertness and heat resistance where the septa will see repeated autoclaving or contact with reactive samples. A serrated surface grips a needle tip more securely on repeated puncture, while a non-serrated (smooth) surface is the simpler option for single or infrequent access. Confirm tube or vial neck diameter against the 12-25mm size range when ordering.
