3M Zeta Plus 16NZA Encapsulated Filter System

• Clarification of cell cultures and fermentation broths in biopharmaceutical production.
• Pre-filtration for sterile filtration steps in vaccine and plasma processing.
• Removal of aggregates and impurities in protein purification processes.
• Processing of media and buffers in laboratory and pilot-scale bioprocessing.
• Small-batch filtration in food and beverage industries for clarity and particle removal.

Typical throughput

For this class of encapsulated filter system, throughput can vary significantly based on the fluid viscosity and particle load, but typically ranges from several litres per hour to tens of litres per hour.

Filter media

Units of this type commonly utilise advanced depth filter media, often incorporating charge-modified materials for enhanced contaminant removal.

Operating pressure

Typical operating pressures for encapsulated systems are generally low to moderate, commonly up to 3-4 bar.

Footprint

As an encapsulated system, the footprint is relatively compact for its capacity, designed for ease of integration into laboratory or pilot-scale setups.

Connectivity

Commonly features sanitary connections such as hose barb or tri-clamp fittings for straightforward integration into fluid paths.

Maintenance requirements

Being a single-use, encapsulated system, maintenance is minimal, primarily involving proper installation and disposal after use.

• What are the benefits of an encapsulated filter system?

  Encapsulated systems offer ease of use, reduced operator exposure to process fluids, and simplified disposal. They are designed for single-use applications, minimising cleaning validation requirements.

• Is this system suitable for sterile filtration?

• Can this unit be used with different filter grades?

• What kind of pump is needed to operate this system?

• Is this system suitable for GMP environments?

Laboratory filtration systems are valued for reliability and durability, making them suitable for used purchase when sourced carefully. Buyers typically prioritise checking membrane and filter condition, as replacement costs can be significant. Industry sentiment favours systems from established manufacturers known for consistent performance. Common strengths include robust construction, compatibility with various applications, and availability of spare parts. When assessing used units, verifying maintenance history and operational specifications remains essential for ensuring continued performance in biotech and pharmaceutical environments.
