Volumetric flasks are highly transparent, easy to clean, and meet Class A tolerances. Flasks are molded PFA, which is highly resistant to heat and chemical contamination. PFA surface properties offer superior clean-up compared to glass and reduces risk of sample carryover in trace analysis applications. Screw cap design provides reduced contamination risk, compared to traditional stopper design.  Application: Suitable for storing and packing high concentration, high purity and strong corrosive drugs and chemical reagents and standard samples.Such as: the State Oceanic Administration for the storage of ocean seawater standard and mercury standard solution;Antarctic Research Team of University of Science and Technology of China for sample collection;China Institute of Metrology for storage of standard liquid.
