Product Description
A thicker silicone layer gives a septum extra resealing power for repeated needle access. These 24 mm septa combine a thin PTFE barrier with a substantial silicone backing, making them a reliable choice for vials that are sampled more than once.
This listing is for Kimble catalog number 73818A-24: PTFE/Silicone Septa, 0.005 in PTFE / 0.120 in Silicone, 24 mm, Case of 144. Each septum has a 0.005 inch PTFE face laminated to 0.120 inch silicone. The PTFE layer faces the sample to provide chemical resistance, while the thick silicone reseals after puncture.
