About volumetric flask, our PFA flask belonds to A class, resistance to strong acid, alkali and various organic solvents, smooth inner wall, material stability much better, low blank value of metal elements, lead and uranium contents are less than 0.01ppb non-leachable, ensure the ultra clean background 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 R...

Photovoltaic, semiconductor, solar energy and other industries, silicon wafer, wafer, glass, liquid crystal screen, battery wafer, as we know, these advanced material is expensive, when cleaning it, we must be careful and ensure the items container anti-corrosion, so that make sure the advanced materials in perfect condition during washing process. PFA wafer c assette, container  of wafer can be customized and designed by customers' request, able to resist strong acid, strong hydrofluoric acid, strong base and heat up to 200~220ºC, use to deliver wafers in acid & base process of Fabrication factory. One-piece molded PFA construction, designed to be used in containers with an opening of at least 3 inches in diameter.  Chemically inert and resistant to temperature extremes, they are an excellent choice for holding or immersing small parts or sample material in corrosive or solvent baths.  A convenient hook allows the dipper/sieve to be hung from the rim of the cont...

Teflon flasks usually have a round-bellied and narrow-necked appearance, which is significantly different from a beaker.  Its narrow mouth is used to prevent the solution from splashing or to reduce the evaporation of the solution, and can be used with rubber stoppers to connect other PFA equipment.  When the solution needs a long time to react or heat to reflux, a polytetrafluoroethylene flask is generally used as a container.  The opening of the flask does not have a protruding notch like a beaker, and it is easier to flow down the outer wall when the solution is poured, so usually a PTFE stirring rod is used to lightly touch the mouth of the bottle to prevent the solution from flowing down the outer wall.  Because the mouth of the flask is very narrow, it is not suitable for stirring with a tetrafluoroethylene stirring rod. If you need to stir, you can hold the mouth of the bottle and turn your wrist slightly to mix smoothly. If heating to reflux, put a magnetic s...

A Chromatography column is a device used in chromatography for the separation of chemical compounds. A chromatography column contains the stationary phase, allowing the mobile phase to pass through it. Chromatography columns of different types are used in both gas and liquid chromatography. Characteristics: ★ Reproducible: PFA microcolumn can be used for many times, greatly saving the cost of experiment; ★ Visibility: PFA transparent cylinder in the separation of color samples, you can directly see the separation of color strip sieve plate: can provide a variety of particle size sieve plate, excellent distribution effect, to achieve better separation degree of large sample load, can be customized according to your experiment; ★ Ultra-pure PFA inert materials, low material background; ★ One molding, no welding gap, liquid flow out smoothly, ensure durable.
