Constructed from high-quality polyethylene, this microcatheter distinguishes itself through its durability and chemical resistance, making it suitable for diverse research scenarios. A key feature of this device is its dramatically reduced inner volume, which significantly decreases fluid waste and enhances the precision of fluid delivery—critical for experiments that require exact fluid dosages. Additionally, its design for direct use with industrial-standard syringes eliminates the need for additional adapters, streamlining the experimental setup and promoting a more efficient workflow.
