A. Hopf High-Flow Stopcocks
A. Hopf designs and manufactures highperformance medical stopcocks trusted by device manufacturers across Europe. To evaluate their performance, A. Hopf conducted internal comparative tests* with four widely used stopcocks available on the market.

Key results (under defined test conditions):
- The flow rate of A. Hopf stopcocks is on average 15% to 36% higher, including in
comparison with products marketed as “high flow.”
- Torsion tests revealed that the handles of their stopcocks are on average 12% to 39%
easier to turn, supporting smoother and more consistent handling.
- Water pressure tests showed an average pressure resistance 14% to 30% higher than
that of other products tested.
- Leak tests showed a gain of 12% to 22% compared to other products tested.
For medical applications such as enteral nutrition, where highly viscous liquids can impact flow performance, A. Hopf stopcocks’ 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 A. Hopf stopcocks a dependable choice for a wide range of medical device applications.
