What are the benefits of using LOONG Filtration filter cartridges in the life science industry?
LOONG Filtration's filtration solutions are integrated into key stages of drug development and production. Our filtration materials are FDA compliant and meet applicable USP biosafety requirements, while our cleanroom operations follow ISO 9001 and GMP guidelines. These solutions help support process scale-up, improve production efficiency, shorten time-to-market, and optimize overall filtration costs.
What are the key factors to consider when selecting a filter cartridge?
Important factors include micron rating, flow rate, chemical compatibility, operating pressure, temperature, and the type and concentration of contaminants to be removed. Our engineering team can help evaluate your process requirements and select a suitable filter element.
What construction configurations are available for LOONG's filter cartridges?
LOONG's filter cartridges are available in four main construction types: depth, pleated, pleated-depth, and string-wound or spiral-wound configurations.
What is the difference between surface filtration and depth filtration?
Surface filtration captures contaminants primarily on the surface of the filter media, particularly particles larger than the effective pore size. Depth filtration captures contaminants throughout the internal media structure, allowing particles to be retained at different depths within the filter.
Does LOONG Filtration provide one-stop filtration solutions?
Yes. LOONG Filtration offers a broad range of filtration products designed for different applications and process requirements. Our comprehensive product portfolio helps simplify the purchasing process by providing customers with multiple filtration solutions from a single supplier.
