K Pure Nylon66 Pleated Filter membrane
K Pure Nylon66 Pleated Filter Cartridges Membrane: High-Performance Filtration
Our K Pure N66M Nylon66 Pleated Filter SEREIS membrane pleated filter cartridges are engineered for high-performance filtration of aqueous solutions and a wide range of organic solvents. Constructed using multi-pleated hot melt welding technology, these filters provide consistent and reliable performance across various biological preparation processes.
The hydrophilic nature of Nylon66 Pleated Filter membranes eliminates the need for wetting agents, ensuring purity and minimizing extractables when filtering aqueous solutions. These membranes are flexible, durable, and tear-resistant, offering excellent mechanical strength. They can also be autoclaved for sterilization, enhancing usability in cleanroom and sterile environments.
Engineered for Purity and Strength
The K Pure Nylon66 Pleated Filter series stands out due to its unique construction and material science:
- Naturally Hydrophilic: Unlike other membranes, Nylon66 Pleated Filter is inherently hydrophilic. This means it wets instantly with water without the need for surfactants or wetting agents, significantly reducing the risk of extractables.
- Multi-Pleated Hot-Melt Construction: We utilize advanced thermal welding to bond the filter components. This hardware-free assembly ensures a leak-proof seal and maintains cartridge integrity even under high-pressure differentials.
- Exceptional Mechanical Durability: Nylon 66 fibers are famously flexible and tear-resistant. This durability allows the filter to maintain a consistent pore structure, preventing “particle bypass” during fluctuating flow rates.
Versatile Healthcare and Lab Applications
The chemical compatibility and sterile-ready design make these cartridges ideal for:
- Biological Preparations: Safe filtration of reagents, buffers, and cell culture media.
- Organic Solvent Filtration: High resistance to a wide range of solvents used in pharmaceutical manufacturing.
- Aqueous Solution Purification: Ideal for high-purity water systems where low-extractable profiles are mandatory.
- Cleanroom Environments: Manufactured and packaged for immediate use in controlled environments.

K Pure Series Comparison: Choosing the Right Filter
Selecting the correct membrane depends on your specific fluid chemistry, the required micron rating, and the end-goal of your filtration process.

1. Use Pure Health Dialysis Series IF:
- You are operating in a clinical renal care environment.
- You need to remove metabolic toxins (Urea, Creatinine) while retaining vital blood proteins.
- Your priority is maximum biocompatibility and single-use safety standards.
2. Use K Pure Borosilicate Glass Fiber IF:
- You are performing pre-filtration for high-viscosity biological liquids.
- You need a reliable vent filter for air/gas to protect sterile tanks.
- You are dealing with high levels of rigid particulates and need a filter that won’t clog quickly (High Dirt-Holding).
3. Use K Pure Nylon 66 IF:
- You are filtering organic solvents or high-purity aqueous solutions.
- You want to avoid “wetting agents” or pre-flushing (Nylon 66 is naturally water-loving).
- You require a membrane with high mechanical strength and the ability to be autoclaved repeatedly.
Frequently Asked Questions (FAQ)
Q: What are the primary benefits of using Nylon 66 over other membranes?
A: Nylon 66 is favored for its natural hydrophilicity and wide chemical compatibility. It handles both water-based fluids and organic solvents exceptionally well, whereas materials like PES or PVDF may require specialized coatings or pre-wetting.
Q: Can K Pure Nylon 66 cartridges be sterilized?
A: Yes. These cartridges are designed to be autoclaved, making them perfect for sterile biological processes and cleanroom applications where microbial control is essential.
Q: Does the filter release any chemicals into the fluid?
A: Because the K Pure series uses hot-melt welding technologyrather than adhesives or glues, and the Nylon 66 requires no wetting agents, the level of extractables is kept to an absolute minimum, ensuring the purity of your filtrate.
Q: Is Nylon 66 compatible with all chemicals?
A: While it has excellent resistance to organic solvents and alkaline solutions, it is generally not recommended for use with strong acids or strong oxidizing agents. Always check a compatibility chart for specific chemical concentrations.
Q: How does the “multi-pleated” design benefit my process?
A: The pleated structure maximizes the effective filtration surface area. This results in lower initial pressure drops and a much higher dirt-holding capacity, which translates to longer filter life and fewer production interruptions.
Q: Can I use the Nylon 66 filter for dialysis?
A: No. Dialysis requires specific Hollow Fiber technology (PS/PES) designed for blood contact. While Nylon 66 is biocompatible for many lab uses, it is not designed for the specialized diffusion and convection requirements of a hemodialyzer.
Q: Why is Borosilicate Glass better for venting than Nylon?
A: Borosilicate Glass is naturally hydrophobic, meaning it repels water. This prevents “blinding” (blockage) caused by moisture in the air, allowing gases to pass through freely while keeping contaminants out.
Q: Which filter lasts the longest?
A: The Borosilicate Glass Fiber typically has the longest service life in high-particulate environments because its “depth” structure traps dirt throughout the media, whereas the Nylon 66 membrane is a “surface” filter that can blind faster if not protected by a pre-filter.
