PFA gas scrubbing bottle is a vessel for washing impurities in gas. It absorbs impure gas by bubbling (dissolving or due to chemical reaction) through a selected suitable liquid medium, so as to wash away impurity gas, and get the purify gas. During the design process, the tetrafluoro balls are surrounded by small holes. Pay attention: 1. The gas scrubber is filled with the selected liquid to scrub the gas and remove the moisture or other gas impurities. When using, pay attention to the flow direction of the gas, the inlet pipe and the outlet pipe cannot be reversed; 2. The gas washing bottle cannot hold alkaline liquid detergent for a long time. After use, pour the detergent into a reagent bottle with a rubber stopper and store it for later use, and clean it with water. The bottle can also collect gas and calculate the volume of gas.

The funnel wall has no adhesion and adsorption to the solvent, can be completely emptied, the interface is clearly visible, and the sealing is good, which can prevent the penetration of chemicals in the separatory funnel; the piston device is easy to remove and easy to clean; It is convenient for the user to observe the liquid change in the cavity during the actual sample separation; the control valve made of high-purity experimental grade PTFE can flexibly control the flow; compared with the glass separatory funnel, the advantage is that it can separate hydrofluoric acid, and It is not easy to damage, can be used for a long time, the inner wall is smooth, does not adhere to any substances, and is easy to clean.

Microcolumns are used to perform ion-exchange sample preparation in geochemistry. Our PFA microcolumn has a variety of sizes of liquid storage and capillary. Special non-welded microcolumns (The integrated mold is cast into a reservoir and the capillary is connected seamlessly). We can also customize microcolumns. Welcome to consult.   Sizes: Common specifications are 1.5ml 15ml 30ml (integrated growth, tube length limit 195mm, supporting different sieve plates according to the number of resin mesh) At the same time can be customized 3ml, 7ml and other specifications of micro column, to meet the experimental needs of customers

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.

1. The disposable use of ordinary plastic microtips leads to the need for constant replacement, which is time-consuming and costly; 2. PFA plastic pipette tips, low blank value of metal elements (lead and uranium content less than 0.01ppb), suitable for ICP-MS analysis, trace analysis and other experiments; 3. PFA plastic pipette tips can be customized in various sizes, suitable for different types of pipettes; 4. PFA plastic tips do not need to be replaced frequently, and its superior and stable performance enables it to be used for a long time, multiple times, and repeatedly, thereby reducing the number of replacements and effectively saving costs; 5. Professional manufacturers customize PFA plastic tips, fine craftsmanship, no burrs, smooth and easy to clean

Binzhenghong hotplate is a digestion or acid drive equipment commonly used in elemental analysis laboratories. It is made of aluminum alloy or graphite, which heats up quickly and uniformly. Teflon PFA coating on the surface for effective corrosion protection. Its advantage is humanized customization(Its size can be customized according to the requirements of laboratory decoration). Exquisite details:The power cord is sheathed with PFA sleeves and no exposed metal parts, which minimizes interference to the experiment and has a longer service life. It has 4 strengths:  1. heating speed, full uniform heating  2.high efficiency,can heat several samples at the same time  3.simple operation, easy to use. Long service life  4. can customized different holds according to different utensils

1.Can meet the detection limit requirements of ICP and ICP-MS and provide laboratory-grade ultra-pure acid in harsh analytical applications. The containers used are Teflon corrosion-resistant non-adsorption plastics; 2.Experiments show that the metal impurity content can be reduced to about 0.01ppb after the acid with a metal impurity content of about 10ppb is distilled once. If the acid requirements are higher, the number of purifications can be increased; 3.All parts in contact with acid are made of purity PFA; 4.No water condensation required, air condenses naturally; 5.Closed cavity, no acid gas overflow, safer.

There are many types of wafer carriers, and each has its own application. For example, the front-opening wafer transfer box FOUP can be used in the semiconductor process in the manufacturing plant, the front-opening wafer transport box FOSB can be used for transportation between manufacturing plants, and the wafer flower basket can be used. for wafer cleaning, etc. Fluororesin has an extremely stable molecular structure, so it is hardly affected by light, temperature and chemicals, and is the "king of resins" that subverts the inherent concept. In the process of cleaning chips, high-purity chemicals are required, and fluoropolymers are the only materials that can contain and transport the high-purity chemicals used in the manufacturing process, achieving the extremely high stability and purity required for semiconductor manufacturing.

Material: PFA Withstand tampreture range:-200°C to 260°C Specification: 3ml~180ml Matching cover: 21mm~59mm Our sample vials always can be the best choice for isotopic analysis, mainly used for samples preparation and storage in ultra-purity laboratory around the world. Our factory uses the highest quality PFA material, one-time molding, eliminating product pollution caused by repeated processing. PFA vials with threaded closures are designed primarily for storage of samples. All our molded PFA vials are manufactured from ultra-pure PFA. PFA vials are widely used in the preparation and storage of a variety of samples for sensitive analyses. The flat exterior surface and high service temperature range of PFA vials make them ideal for use directly on a hot plate, and the inert properties of PFA allow for the most rigorous acidic sample preparations without fear of comprising or adulterating the original sample material.
