Made from superior polyethylene, this microcatheter is celebrated for its exceptional durability and extensive chemical resistance, suitable for the varied demands of laboratory research. Its significantly reduced inner volume dramatically decreases fluid waste while enhancing fluid delivery precision, a vital attribute for experiments that necessitate precise fluid measurements. The incorporation of a 4-way stopcock not only ensures seamless compatibility with industrial-standard syringes but also simplifies the experimental setup, obviating the need for extra adapters and thereby boosting procedural efficiency and versatility in controlling fluid direction.
