Manufacturer of HPLC Vials with Caps for Chromatography

Main applications for Plastic vials are atomic absorption, water and protein analysis, capillary electrophoresis, ion chromatography etc.
Optimal choice when working with proteins. Ideal for IC applications

In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Syringe filters can be used in HPLC analysis and IC analysis to filter sample solutions, which is an important step in the sample pretreatment process. 
Non-sterile Disposable Syringe Filters typically consist of a PP housing, which is often made from materials such as polypropylene. The housing contains a filter membrane, which is usually made of materials like PTFE, PVDF, PES, MCE, NYLON, PP, CA, etc. Non-sterile Disposable Syringe Filters are available in a variety of membrane choices, which determine the size of particles or contaminants that can be effectively removed. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes. The choice of pore size depends on the specific application, with smaller pores being used to filter out smaller particles and larger pores for faster flow rates with less fine filtration.

In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment. Syringe filters can be used in HPLC analysis and IC analysis to filter sample solutions, which is an important step in the sample pretreatment process.
