What is this Compact Disc Filter Cartridge mainly used for?
This Compact Disc Filter Cartridge is designed for laboratory, R&D, and small-batch liquid or gas filtration where compact size, low hold-up volume, and reliable filtration are important. Typical applications include cell culture gas treatment, bioreactor inlet filtration, vacuum system protection, precision instrument protection, and other small-scale processing applications.
What filter media are available for this Compact Disc Filter Cartridge?
Available media include PP, MCE, Nylon, PES, PTFE, hydrophilic PTFE, PVDF, hydrophilic PVDF, and glass fiber. The correct media should be selected according to the process fluid or gas, required filtration accuracy, chemical compatibility, wettability, protein-binding requirements, and whether the application involves liquid or gas filtration.
How do I choose the right micron rating for this disc filter?
The correct micron rating depends on the filtration objective, particle or microbial retention requirement, contamination level, process medium, flow rate, and downstream cleanliness target. Available ratings include 0.1 μm, 0.22 μm, 0.45 μm, 0.65 μm, 1.0 μm, 3.0 μm, 10 μm, and selected combined ratings.
Can this Compact Disc Filter be used for both liquid and gas filtration?
Yes. Different membrane materials allow the filter to be configured for either liquid or gas applications. Hydrophilic membranes are generally more suitable for aqueous liquids, while hydrophobic media such as PTFE are commonly selected for gas filtration. Final suitability should be confirmed according to the process medium and operating conditions.
What operating pressure and temperature limits should be considered?
The listed maximum operating temperature is 60°C. For liquid service, the maximum operating pressure is 3.5 bar at 23°C and 3.0 bar at 60°C. For gas service, the listed values are 3.0 bar at 23°C and 2.5 bar at 60°C. Actual limits also depend on the selected membrane and process conditions.
How do I confirm whether this disc filter fits my tubing or laboratory system?
Compatibility should be checked according to filter diameter, inlet/outlet size, tubing dimensions, flow requirement, and connection type. The listed outer diameter is approximately 72 mm, with compatibility for 8–12 mm tubing and 1/4"–1/2" Pagoda-type connections. Final fit should be confirmed against the actual installation dimensions.
