Crafted from premium polyimide, this microcatheter is celebrated for its outstanding durability and comprehensive resistance to chemicals, making it perfectly suited for the rigorous demands of laboratory use. It features a dramatically reduced inner volume, crucial for minimizing fluid waste and maximizing the accuracy of fluid delivery, particularly in experiments that require exact fluid dosages. The introduction of a 1-way stopcock not only ensures direct compatibility with industrial-standard syringes but also simplifies the experimental setup by eliminating the need for additional adapters, thereby enhancing procedural efficiency.
