Crafted from premium polyethylene, this microcatheter is celebrated for its exceptional durability and broad chemical resistance, accommodating the varied demands of laboratory research. The incorporation of a dramatically reduced inner volume significantly curtails fluid waste and boosts the accuracy of fluid delivery, a vital attribute for conducting experiments with stringent fluid dosage requirements. The addition of a 1-way stopcock enhances direct compatibility with industrial-standard syringes, removing the necessity for extra adapters and thus streamlining the experimental setup, which in turn improves workflow efficiency.
