Constructed from superior polyurethane, this microcatheter boasts outstanding durability and resistance to a wide array of chemicals, perfectly suited for the varied demands of laboratory work. A significantly reduced inner volume is a hallmark of its design, minimizing fluid waste and maximizing the accuracy of fluid delivery—essential for conducting precise experiments. The addition of a 4-way stopcock not only ensures effortless compatibility with industrial-standard syringes but also simplifies the experimental setup by removing the need for additional adapters, thereby enhancing procedural efficiency and offering versatile control over fluid direction.
