Microbial Limit Tester Membrane Filtration System – ZR-1140 | JUNRAY

The ZR-1140 Microbial Limit Tester is a membrane filtration system designed to determine whether a non-sterile pharmaceutical product complies with established microbial quality specifications. The system enables reliable microbial limit testing (MLT) by filtering samples through sterile membranes and supporting efficient microorganism recovery.

Designed for laboratory environments in pharmaceutical, biotechnology and quality control applications, the ZR-1140 integrates multiple filtration heads and a high-performance diaphragm pump to ensure stable flow rates and consistent filtration results.
