Bacteria Viability Test

 

细菌生存验证图-中文


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.

 

Purpos

Prove the brevundimonas bullata in aqueous solution are trapped rather than in a specific product is not enough to verify the filter could meet the requirement of aseptic filtration technology in the production process.

Principle and method selection

To choose the right challenge test method, the tested microorganism should be directly inoculated to the carrying fluid (product or substitute) to prove its survivability. To the non-sterilized technology and fluid, the preferred method for bacteria viability test is: the tested microorganism directly inoculated to the product. While testing the sterilized product, it should increase bacterial concentration or choose substitute according to the sterilization grade.
