A. Hopf High-Flow Stopcocks

Reliable performance for demanding medical applications.
At A. Hopf, we design and manufacture high-performance medical stopcocks trusted by device manufacturers across Europe. To evaluate their performance, we conducted internal comparative tests* with four widely used stopcocks available on the market.
Key results (under defined test conditions):
For medical applications such as enteral nutrition, where highly viscous liquids can impact flow performance, our open-gate handle design, rather than a traditional bore configuration, helps maintain an unobstructed fluid pathway and minimises the risk of flow restriction. This robust design, combined with high-quality materials and decades of experience in the field of nutrition, makes our stopcocks a dependable choice for a wide range of medical device applications. *Full details of the internal tests are available upon request at contact@promepla.com.
