An essential part of containing and storing dry/liquid samples is the use of vial closures, which come in various materials and sizes. We offer a wide selection of screw-caps, corks, and plastic stoppers to suit any type of application. Our screw caps and stoppers come individually packaged for easy ordering with no minimum order quantity, while our corks are sold in bags of 500 pieces. Each of these different closure types provide a secure seal, allowing for safe storage and transportation of your samples.
