Frequently Asked Questions
What is DeltaMax® Polypropylene Depth?
DeltaMax® Polypropylene Depth is an absolute-rated depth filter designed for clarification, polishing, and prefiltration of process fluids. Constructed entirely from polypropylene, it delivers high flow rates, broad chemical compatibility, and excellent dirt-holding capacity, making it ideal for removing particulate contamination in demanding filtration applications. :contentReference[oaicite:0]{index=0}
What applications is DeltaMax® Polypropylene Depth used for?
DeltaMax® filters are used across biopharmaceutical, chemical, and industrial processes where efficient particulate removal and process protection are critical.
- Clarification of cell culture fluids and process intermediates
- Prefiltration prior to membrane or sterilizing-grade filtration
- Removal of soft contaminants such as gels and deformable particles
- Filtration of buffers, media, reagents, and aqueous solutions
- Applications in pharmaceutical, beverage, water, and chemical processing
What retention ratings and formats are available for DeltaMax® Polypropylene Depth?
DeltaMax® filters are available in a range of absolute-rated retention levels to match specific clarification needs. They are offered in multiple scalable formats, including cartridges, small flow elements (SFE), capsule filters, and high-capacity assemblies such as UltraCap® and UltraCap® H.D., enabling seamless transition from laboratory to production scale. :contentReference[oaicite:1]{index=1}
What makes DeltaMax® Polypropylene Depth unique?
DeltaMax® filters are engineered for high throughput and long service life, even in applications with high particle loads. Their depth structure provides excellent dirt-holding capacity and maintains flow performance under challenging conditions. They are particularly effective for processing fluids containing soft contaminants, such as gels, that can rapidly foul other filter types. :contentReference[oaicite:2]{index=2}
How does DeltaMax® Polypropylene Depth improve downstream filtration?
By removing larger particles and difficult-to-filter contaminants upstream, DeltaMax® significantly reduces fouling of downstream membrane filters. This extends filter life, improves throughput, stabilizes process performance, and helps maximize product recovery.
Is DeltaMax® Polypropylene Depth suitable for regulated biopharmaceutical manufacturing?
Yes. DeltaMax® filters are manufactured from biologically inert, FDA-listed materials and meet industry expectations for purity and performance. They are suitable for use in cGMP-compliant processes when properly validated within the application. :contentReference[oaicite:3]{index=3}
Can DeltaMax® Polypropylene Depth be sterilized?
DeltaMax® filters can be sterilized depending on configuration, including autoclaving and compatibility with single-use systems. Capsule formats can be integrated into sterile workflows where required.
What other products are commonly used with DeltaMax® Polypropylene Depth?
DeltaMax® is typically used as part of a multi-stage filtration strategy:
- Upstream depth media: ALpHA® and Vangard® filters for staged clarification
- Downstream membrane filters: SteriLUX® (PVDF), STyLUX® (PES), and EverLUX® (PES) for final or sterilizing filtration
- Single-use systems: One-Touch® assemblies and capsule filters for closed, scalable processing
This layered approach improves filtration efficiency, reduces fouling, and ensures consistent process performance.
