Product Description
Open Hole Screw Cap with Slit PTFE/Silicone Septa, Black 8-425mm (1000/Case)
These open hole closures are molded from durable polypropylene with a ribbed finish for a secure grip during capping and decapping. Each cap comes pre-lined with a slit 0.060" PTFE/Silicone septum. The slit relieves vacuum during sample withdrawal and reduces needle wear, which makes these caps a strong choice for repeated autosampler injections. The 8-425mm thread fits standard 8mm screw thread vials for HPLC, GC, and general laboratory sample storage. Each case holds 10 shelf packs of 100 closures in plastic bags, so you can keep stock clean and open only what you need.
