Pre-sterilized Nylon-66 Membrane Centrifugal Filters Type- CFNN

Pre-sterilized Nylon-66 Membrane Centrifugal Filters Type CFNN are advanced centrifugal filtration devices designed for rapid, sterile, and contamination-free filtration of small-volume samples. These filters are ideal for laboratories that require high precision, sterility, and reliable performance in analytical and biological applications.

Widely used in international markets such as the USA, UK, Germany, and Europe, these filters ensure consistent results with minimal sample handling.

What are Pre-sterilized CFNN Centrifugal Filters?

These are ready-to-use sterile centrifugal filter units made with a Nylon-66 membrane, designed to remove particles and contaminants using centrifugal force.

Being pre-sterilized, they eliminate the need for additional sterilization steps, making them ideal for sensitive and sterile applications.

Where Are These Filters Used?

Pre-sterilized CFNN filters are commonly used in:

• HPLC Sample Preparation: Removal of particulates before analysis
• Biological & Biotech Applications: Filtration of proteins, buffers, and culture samples
• Pharmaceutical Labs: Sterile sample processing
• Research Laboratories: Purification and clarification of solutions

They are perfect for applications requiring clean, sterile, and particle-free samples.

Why Use Pre-sterilized CFNN Filters?

These filters are preferred due to their speed, sterility, and ease of use.

Key reasons include:

• Pre-sterilized and ready to use
• Eliminates contamination risk
• Fast filtration using centrifugation
• High chemical compatibility
• Minimal extractables for accurate results

They are ideal for time-sensitive and sterile laboratory workflows.

Material and Construction

These filters are made from high-quality Nylon-66 membrane, offering:

• Hydrophilic surface for smooth filtration
• Strong mechanical stability
• Wide chemical compatibility
• Low extractables

Typical Specifications:

• Membrane: Nylon-66
• Pore Size: 0.2µm, 0.45µm
• Format: Centrifugal filter unit
• Sterility: Pre-sterilized (Gamma / EO)
• Capacity: Small volume (approx. 0.5ml – 15ml)

Working Principle

Pre-sterilized CFNN filters operate on a centrifugal filtration mechanism:

1. Sample is added to the filter unit
2. Unit is placed in a centrifuge
3. Centrifugal force drives liquid through the membrane
4. Particles and microbes are retained
5. Filtered liquid collects in the receiving tube

This ensures fast and efficient sterile filtration.
