Chemical Compatibility Test confirms that there are no negative impacts between the filter and the process fluid. Two aspects must be considered when performing, the impact of the process fluid on the performance of the filter and possible contaminants released by extractables, precipitates, or particles.

Chemical Compatibility - Customer Case

Pharmaceutical Company ‘A’ has been using a PES membrane to filter their feed liquid. Cobetter Validation Center performed a chemical compatibility and discovered that the PES membrane used was not compatible for their feed liquid. After additional analytical test and based on the chemical compatibility requirements, Cobetter hydrophilic PTFE membrane was more compatible with their feed liquid. The new membrane proposed by Cobetter Validation Center significantly increased product quality and eliminated potential risks.
