Millipore Opticab XL 4 Capsule

• Sterile filtration of pharmaceutical liquids, including injectables and ophthalmic solutions.
• Clarification and pre-filtration in biopharmaceutical manufacturing processes.
• Virus filtration and removal in cell culture media and buffer preparation.
• Point-of-use filtration for critical laboratory and small-scale production applications.
• Filtration of high-value or sensitive biological products where minimal hold-up volume is critical.

Typical capacity

For this class of capsule, flow rates can range from a few litres per hour up to several hundred litres per hour, depending on the specific membrane and fluid viscosity.

Power supply

Filtration capsules like the Opticab XL 4 are passive components and do not require an external power supply. They are typically integrated into a pumped fluid system.

Materials of construction

Commonly, these capsules feature a polypropylene housing with various membrane materials such as PVDF, PES, or PTFE, selected for chemical compatibility and filtration efficiency.

Typical filtration area

Units of this type often have a filtration area ranging from 0.1 m² to 0.5 m², influencing throughput and capacity.

Operating pressure

Maximum operating pressures typically fall between 3 to 5 bar (45 to 75 psi), depending on the capsule design and membrane type.

Connections

Commonly found with sanitary flange connections (e.g., Tri-Clamp) or hose barb fittings for easy integration into process lines.

Maintenance requirements

As disposable units, these capsules require no internal maintenance; replacement is the primary maintenance activity.

• What is the primary benefit of using a disposable capsule like the Opticab XL 4?

  Disposable capsules eliminate the need for cleaning, sterilisation, and validation of reusable filter housings, significantly reducing labour and turnaround times in critical applications.

• Can this unit be used for sterile applications?

• What type of fluid is this capsule suitable for?

• How do I determine the correct capsule for my application?

• Is this capsule suitable for high-viscosity liquids?

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.
