Overview
GVS MCE (Mixed Cellulose Esters) Membrane Filters are unsupported, hydrophilic microporous membranes. Their excellent high flow rates and high throughput have made them a standard choice for microbiological testing, particularly for bioburden and sterility testing applications.
What’s Special
Hydrophilic membrane material: Suitable for direct filtration of aqueous samples.
Unsupported membrane design: Facilitates efficient microbial retention and growth.
High flow rate and throughput: Reduces filtration time and improves laboratory efficiency.
✔ Excellent microbial recovery and culture performance: Ensures reliable microbiological testing results.
✔ Compatible with membrane filtration (MF) methods: Ideal for microbiological analysis and quality control applications.
