Product Description
Draw samples or add reagents by needle without ever opening the bottle. These silicone septa fit open-top GL screw caps and let syringes pass through while the cap stays tightened in place. That reduces exposure to airborne contamination and makes repeated sampling from media, reagent or solvent bottles quicker and cleaner.
This listing is for DURAN catalog number 292460906: Silicone Septum Seal Peroxide cured silicone, GL 25, Pack of 100. Each septum is made from peroxide-cured silicone with a hardness of 60 Shore A and sits inside an open-top screw cap with a central aperture. Sizes cover GL 14, GL 18, GL 25, GL 32 and GL 45 bottles, in 2 or 3 mm thickness depending on size. The seals are autoclavable and come in packs of 100. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
