Nanjing Binzhenghong Instrument Co.,Ltd is a professional laboratory product manufacturer which mainly has laboratory products based on PTFE/PFA/FEP and other materials, such as: beaker/reagent bottle/stirring bar/tweezers/funnel/volume flask/crucible/stirring rod/water tank/reaction bottle/washing bottle/ The measuring cylinders/etc.
Our products are sold all over the world (such as CUG, IGCAS, SGS, etc. )and are well received by experimenters in the semiconductor, electronics, and pharmaceutical industries, and are widely used in the chemical industry.
1. Material and chemical stability
Material: PFA is a perfluoroalkoxy polymer with excellent chemical stability.
Corrosion resistance: It can resist the corrosion of various strong acids, strong alkalis, aqua regia, hydrofluoric acid and organic solvents, and is suitable for the storage and reaction of various corrosive reagents.
2. Physical properties
High temperature resistance: The operating temperature range is wide, from -200ºC to +260ºC, and it can maintain the stability of the structure and the safety of operation under high temperature conditions.
Transparency: PFA material is translucent, which is convenient for observing the state and reaction of the liquid during the experiment, and helps the experimenters to better understand and analyze the reaction process and results.
Lightweight: Compared with glass flasks, PFA flasks are lighter, easier to carry and operate, and reduce the labor intensity of experimenters.
3. Design and convenience
Round bottom design: The bottom is round, which can better heat the liquid evenly and promote the convection of the liquid, thereby accelerating the rate and effect of the reaction. At the same time, the round bottom design also makes the flask more stable when placed.
Multi-mouth design: It can be processed into multi-mouth flasks such as double-mouth, three-mouth, and four-mouth according to needs, which is convenient for connecting other utensils such as condensers to meet various experimental needs.
Smooth interior: The interior of the PFA flask is smooth and has no edges and corners, which is not easy to leave residual samples and is easy to clean, reducing the risk of sample carryover in trace analysis applications.
4. Wide application
PFA round-bottom flasks are widely used in biopharmaceuticals, fluorine chemicals, new materials and other industries for various experiments and production processes, such as cell culture, drug synthesis, chemical reactions, solvent storage, etc.
