Constructed from high-quality polyurethane, this microcatheter offers excellent durability and chemical resistance, meeting the rigorous demands of laboratory environments. Its design includes a dramatically reduced inner volume, significantly minimizing fluid waste and enhancing the precision of fluid delivery—vital for experiments requiring meticulous fluid measurements. Furthermore, the convenience of direct compatibility with industrial-standard syringes streamlines the setup process, eliminating the need for additional adapters. The inclusion of a nitinol stylet, with its remarkable flexibility and memory shape properties, provides superior guidance and placement accuracy within the experimental framework.
