Organic phase needle filterMainly used for filtering mobile phases and samples in chromatographic analysis. If impurities exist in the sample and solvent, they not only cause damage to the chromatography instrument and column, but also have a significant impact on the analysis results. Organic needle filters have a good effect on protecting chromatographic columns and systems from contamination, while also improving the sensitivity and accuracy of analytical results. Widely used in drug analysis, food testing, environmental monitoring, protein removal, and sterility testing.
　　
The shell is made of chemically stable polypropylene (PP) material and comes in different colors to facilitate users in distinguishing products of different specifications and materials, avoiding confusion. The filter membrane adopts imported high-performance filter membrane, with stable product quality and good reproducibility, making it an ideal choice for laboratory sample filtration. The standard interface is convenient for connecting with various syringes, and can also be directly connected to the needle of the 7725 valve for direct injection after filtration.
　　
　　Organic phase needle filterWidely used in various analytical processes. Nylon filter membrane is suitable for filtering aqueous and organic solvents, such as sample preparation for liquid and gas chromatography. Its characteristics are high flux, low solubility, and good mechanical strength. Nylon's excellent physical properties can meet the demanding analytical needs of various testing conditions.
　　
　　Organic phase needle filterThe main characteristics are:
　　
The pore size is relatively uniform, the porosity is high, there is no medium detachment, the texture is thin, the resistance is low, the filtration rate is fast, the adsorption is minimal, and the cost is low. However, it is not resistant to organic solutions and strong acid and alkali solutions.
　　
Usage: Water injection for hot pressing sterilization in the pharmaceutical industry, and for filtering out particles in large infusion solutions.
　　
Sterilization of thermosensitive drugs (biochemical agents such as insulin ATP, coenzyme A, etc.) using a 0.45 micron filter membrane (or 0.2)
　　
In the field of medicine and health, the detection of C-AmP, C-GmP, and hemochromatosis in human body fluids using thin film method, the determination of Escherichia coli in drinking water, surface water, and well water, and the detection of industrial and mining dust at 0.8-5.0 microns.
