This microcatheter is constructed from premium polyethylene, offering exceptional durability and resistance to chemicals, making it ideal for a variety of research applications. Its significantly reduced inner volume minimizes fluid waste and increases the accuracy of fluid delivery, essential for experiments requiring precise fluid dosages. The integration of a 1-way stopcock enhances its usability with industrial-standard syringes, facilitating direct use without the need for additional adapters and simplifying the experimental setup, thereby improving workflow efficiency.
