Constructed from high-quality vinyl, this microcatheter distinguishes itself with exceptional durability and resistance to a variety of chemicals, suiting the broad demands of laboratory research. Its design significantly reduces the inner volume, crucially minimizing fluid waste while increasing the accuracy of fluid delivery for experiments demanding precise fluid dosages. The inclusion of a 4-way stopcock not only ensures seamless compatibility with industrial-standard syringes but also streamlines the setup process by eliminating the need for additional adapters, thus boosting procedural efficiency and offering versatile control over fluid directions.
