The shell material of needle filter is made of high quality sanitary grade polypropylene. The structure design of the product is precise, which ensures the fluency of filtration, rationalizes the internal space and reduces the waste of samples.
Syringe filter
In the analysis of high performance liquid chromatography (HPLC), the packing of chromatographic column has smaller particle size and is easily blocked by impurity particles. Therefore, samples and solvents need to be pre-filtered to remove particulate pollutants and protect the instrument. Ion chromatography commonly used in environmental analysis also requires that inorganic pollutants should not be introduced into the sample pretreatment. Needle filter can be used in the analysis of high performance liquid chromatography and IC. The filtration of sample solution is an important step in the sample pretreatment process.
One of the disadvantages of the traditional filter is easy to blast. The product is specially designed to withstand blasting pressure up to 7 bar.
The edge part of the filter has threads, which can prevent skid and make the operator feel comfortable.
Stable filter quality and zero difference between batches ensure the consistency of analysis results.
