Millipore Opticab XL 4 Capsule

• High-capacity fluid filtration in biopharmaceutical manufacturing.
• Clarification of cell culture media and buffers in laboratory settings.
• Sterile filtration of critical process fluids.
• Pre-filtration for downstream purification steps.

Typical capacity

For this class of equipment, units are designed for high flow rates, typically handling volumes from several litres up to hundreds of litres per batch or continuous process.

Power supply

These are generally passive filtration units, not requiring electrical power for the filtration process itself, but may integrate into systems with standard laboratory or industrial power (e.g., 230V, 50Hz for pumps).

Filtration area

The 'XL 4' designation commonly indicates a significant filtration area, typically providing several square meters for enhanced throughput and particle retention.

Housing material

Capsule filters of this type typically feature robust, chemically compatible plastic housings, such as polypropylene, suitable for pharmaceutical applications.

Connection types

Commonly found with sanitary flange connections (e.g., Tri-Clamp) or hose barb fittings, suitable for integration into flexible or rigid piping systems.

Operating pressure

Units are typically rated for operating pressures up to 5 bar (72 psi), depending on the specific filter media and housing design.

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.
