Our product range includes marketable canister and bottle closures with internal diameters from 28 to 60 mm and corresponding opening aids, such as canister wrenches. Proven millions of times in hazardous materials, pharmaceuticals and general applications, we manufacture our closures according to the highest purity standards and can make them available to you just in time as bulk goods in cardboard boxes. Our standard and special versions – for example those with degassing, anti-glug, strainer insert or childproof functions – have earned pharmaceutical and hazardous goods approvals at all renowned European testing institutes. Reliable protection and sealing functions can therefore be documented under the highest purity, internal pressure and drop height requirements for many simulants.
