Laboratory Equipment

Lenge Purification Equipment Co., Ltd. and Jiangnan University established the Institute of materials and technology, and the graduate-student workstation. With advanced imported test equipment, standard test procedures and testing proposals, we can provide customers with various test and validation services, such as chemical compatibility, extractables, adsorption, bacterial challenge, bacterial viability, integrity, recycle use, etc.

For different customers, we simulate the produce process under the most disadvantage conditions, and make qualitative and quantitative estimation of dissolution by imported infrared spectrometer, ultraviolet spectrophotometer, HPLC and other equipment, thus make the quantitative analysis of the product absorbed on the membrane.

Purpose

The fluid absorbed on the filter may effects the composition or concentration of the fluid. The absorbable filter materials include membrane, hardware and supporting material.

Principle and method selection

In the processing of technology development, adsorption test generally applied on a small scale and confirm on a large scale. The quantitative analysis by using High Performance Liquid Chromatography(HPLC) is designed to establish pretreatment selection, operating parameters and membrane selection.
