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):
The flow rate of our stopcocks is on average 15% to 36% higher, including in comparison with products marketed as “high flow.”
Our torsion tests revealed that the handles of our stopcocks are on average 12% to 39% easier to turn, supporting smoother and more consistent handling.
Our water pressure tests showed an average pressure resistance 14% to 30% higher than that of other products tested.
Our 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, 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.
