Crafted from premium polyurethane, this microcatheter excels in both durability and chemical resistance, making it suitable for the diverse and demanding environments of laboratory work. Its significantly reduced inner volume is a critical design aspect, drastically reducing fluid waste and optimizing the accuracy of fluid delivery for experiments that demand exact fluid dosages. The convenience of direct use with industrial-standard syringes, now further simplified by the 1-way stopcock connection, eliminates the need for additional adapters, streamlining the experimental setup process. The included nitinol stylet, known for its exceptional flexibility and shape memory, enhances the microcatheter's navigability and placement accuracy.
