HTY-FT223 Pro
The Filter Integrity Tester FT223Pro is a microcomputer-based, intelligent, and highly sensitive precision analytical instrument, independently developed by Tailin, specifically designed to detect the integrity of filter elements and membranes in filtration systems.

Dust-proof & Backflow-proof Design: Easily cleaned to prevent liquid backflow and microbial contamination upstream of the filter.
Full Touch Screen Operation: 10-inch ultra-large capacitive screen with high resolution.
Dust-free High-Fidelity Printing Technology: Data results can be printed out quickly and efficiently and stored for a long time, with a storage period of more than 10 years.
Water-proof Design: IP54 protection level, to prevent the equipment from short circuiting due to sudden splashing of water droplets.
Wireless Transmission: Can be connected to wireless networks, LANs, and supports data remote management and synchronization.
Data Integrity: Compliant with 21CFR part 11, 4-level user access, audit trails, and various forms of backup.

Filter integrity testing is required to ensure the effectiveness of sterile filtration, which is an essential terminal sterilization step for the microbial safety of biopharmaceutical products. Pre-use testing confirms that the filter meets the manufacturer’s specifications and has not been damaged during sterilization. Post-use testing verifies that the filter maintained its integrity during operation and achieved the expected bacterial retention performance.
A filter integrity tester determines filter or membrane integrity by measuring or observing the volume of gas that passes through a pre-wetted filter or membrane under a defined gas pressure gradient.
The main unit consists of three parts: the pressure control unit, the data processing unit, and the connection unit.
