LPTA filter cartridges are featured by permanently hydrophobic PTFE membrane, specially designed for sterile venting and gas application in vaccine manufacturing. They are integrity testable, offering the highest process security, high throughputs, extreme humidity and stringent in-line steam sterilizations. These filters can be steam-sterilizable repeatedly for long service life.

● Cartridges produced in a controlled environment
● Manufactured according to ISO9001 certified Quality Management System

Features and Benefits
● High flow rates and low pressure drop
● High strength, long service life and cost-effective
● 100% integrity testable prior to release
