ALpHA^® G Polyester Microfiber

ALpHA^® G capsule filters are offered in a wide range of configurations to seamlessly scale from lab applications to process development through full-scale production. ALpHA^® G’s unique absolute rated depth type filter media has been optimized for a gamma irradiation cycle commonly used to sterilize single-use systems. The capsule filter’s tapered pore structure provides high flow rates and high throughput, while also delivering extraordinary dirt holding capacity.

ALpHA^® G capsule filters are available in absolute retention ratings from 0.6 μm to 20 μm for clarification applications within biopharmaceutical manufacturing.

Design Features

• Gamma irradiatable – ALpHA^® G capsule filters can be gamma irradiated and provided sterile for immediate use.
• Scalable – Easy to scale-up from capsules with filter surface areas of 0.02 m² to capsules with filter surface areas of 2.5 m².
• Ready to use – ALpHA^® G capsule filters typically don’t require pre-rinse steps before use or post-use rinse and blow down steps for product recovery.
• UltraSnap^® compatible – For large volume processing and applications requiring multistage filtration, ALpHA^® G UltraCap^® H.D. filters can be secured in an UltraSnap^® assembly. This assembly can be delivered as a single pre-sterilized unit for true plug and play functionality.
• Low extractables and endotoxin levels
