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

By testing the chemical compatibility of the filter and process fluid to confirm that the process will not change the performance of the filter.

Principle and method selection

The filter and liquid contacted for a specified time under given condition, the chemical compatibility is judged by, contacting before and after, the integrity, flow rate, weight, appearance and Scanning Electron Microscope(SEM) of the filter and membrane.
