Select Plates By Application

The sieve plate is an important component of the solid phase extraction column/Flash Du, which plays the role of fixing the packing and controlling the flow rate. The sieve plate for Lvyuan SPE/Flash has been specially optimized and it is word-leading in terms of flow rate control, purity, stability and solvent compatibility, and has been adopted by many well known solid phase extraction column brands.

Main feature
The flow rate of the sieve plate is constant, and it will not "perforate" when multiple tubes are used in parallel. The ultra-pure raw material is selected, which is suitable for high-sensitivity analysis. The ultra-thin sieve plate with a thickness of only 1.2 mm can be used to separate different packing layers in a multi-layer SPE column. PTFE sieve the plate is matched with the glass column tube, which can be used for the detection of plasticizes.

Affinity chromatography column sieve plate is especially suitable for affinity chromatography column with Sepharose 4B as matrix, mainly used for recombinant protein extraction, antibody purification or effective component separation.

The Lvyuan sieve plate DNA extraction can choose hydrophilic sieve plate or hydrophobic sieve plate, no DNase/RNase, no PCR inhibitor, 20um or 50um pore size. Hydrophobic sieve plates are mainly used for solid liquid phase separation of bacterial lysates, which require pressurization instead of centrifugation steps: hydrophilic sieve plates are mainly used for the purification process of plasma DNA.

DNA synthesis cartridges are used in single-use synthesis cartridges to immobilize expensive CPG particle bleed The pore size of the DNA synthesis filter element needs to be optimized so that when the liquid is transported upwards, the CPG particles rise and remain in suspension, allowing the particles to mix properly.

Solid phase synthesis (Solid Phase Synthesis) usually refers to the reaction between active functional groups attached to a solid support (such as resin, etc.) and reagents dissolved in an organic solvent.In solid-phase peptide synthesis, the elongation of the peptide chain is carried out on an insoluble polystyrene resin carrier. The C-terminal of the synthesized poly peptide is first reacted with chloromethyl polystyrene resin(benzyl chloride resin) to form a benzyl ester, and then the amino acids that have been protected at the amino terminal are added one by one according to the order of the primary structure of the peptide chain, so that Peptide chain elongation.

The solid-phase method is simpler than the liquid-phase method, the time is shortened, and it can be automated.It has been applied in our country's pharmaceutical industry.

lon chromatography (lon Chromatography) is one of high performance liquid chromatography (HPLC), which is a liquid chromatographic method for analyzing of anions and cations. Compared with photometric and atomic absorption methods, the main advantage of lC is that multiple componentsof the sample can be detected simultaneously. it takes only a short time to obtain all the information about the anions and cations and the composition of the sample.The sieve plate of the ion chromatography pretreatment column is similar to that of the SPE column.

The filter for glycated hemoglobin (HbA1c) assay is made of PEEK and stainless steel filter with the inlay process,PEEK ensures the precision of filtration and stainless steel filter ensures the precision of filtration.After a lot of tests, our filters can completely replace the imported products and can be matched with the main.stream HbA1c analyzers.
