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.

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

Fine Tubes manufactures a range of specialist stainless steel tubes used to produce high-performance and ultra high-performance liquid chromatography (HPLC and UPLC) columns. Our tubes are components in both liquid and gas chromatography columns which are used for analytical and preparative processes across the fields of biochemistry and analytical chemistry. Tightest Tolerance Control The control process during manufacture of these tubes is critical to meet the highest specifications demanded in this area. The percentage Cross Section Area Reduction (% CSAR) through pilgering and drawing is specific to each product’s dimensions and specifications. Surface Finish The ID surface finish is further refined by passivation, polishing or electro polishing processes. OD surfaces are finished down to 0.1μm (0.25μ") and ID down to 0.16μm (0.40μ") and 0.08μm (0.20μ") with electro polishing. Please note that we have a minimum order value of £10,000.

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.

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.
