Gamma Compatible Sterilizing-grade Durapore^® 0.1µm and 0.22 µm Filters

Gamma Compatible Sterilizing-grade Durapore® 0.1µm and 0.22 µm Filters

Superior Filters for the Sterile Filtration of Biopharmaceutical Liquids
Millipore gamma compatible capsule filters combine easy to use disposable technology with proven 0.1µm and 0.22 µm Durapore membrane.

Opticap^™ XL and XLT capsules are designed to meet the growing demand for filtration into large sterile biocontainers. Up to 2000 liters of buffer, media and chromatographic eluents can be processed with these capsules. Millipak^® disposable filter units are ideal for small volume processing and sterile fill and finish applications.

These disposable capsule filters are convenient, safe and supported by Millipore Validation Guides. Overall process efficiency and cost effectiveness are enhanced due to the elimination of cleaning and subsequent validation issues. The hydrophilic Durapore membrane provides high flow rates and throughput, low extractables and particle shedding, and broad chemical compatibility.


Regulatory Compliance
Filters with hydrophilic Durapore membrane are designed, developed, and manufactured in accordance with a Quality Management System approved by an accredited registering body to an ISO^® 9000 Quality Systems Standard and are shipped with a Certificate of Quality. Each Millipak, Opticap XL and Opticap XLT capsule is integrity tested during manufacturing and is supported by a Validation Guide for compliance with regulatory requirements.

For traceability and easy identification, each device is marked with the product name and identifying characteristics.


Multiple Formats Available
Sterilizing-grade hydrophilic Durapore membranes are available in four formats, two pore sizes, and multiple configurations that vary by filtration area and type of inlet/outlet connection. We have a format to meet your application needs.


Millipak Low-Volume Capsule Filters

Millipak filters with hydrophilic Durapore membranes are uniquely designed for the removal of particles and micro-organisms. The stacked disc design allows minimal hold-up volume and no particle shedding, making Millipak units ideally suited for high value-added applications. Each Millipak filter is integrity tested during the manufacturing process.

Millipak filters are available in two different stack sizes. Adjustable, easy-to-turn, upstream vents and drain valves with O-ring seals and hose barb connections allow for easy process control.


Opticap XL and XLT Disposable Capsule Filters

Opticap XL

Opticap XLT

Opticap XL and XLT capsule filters eliminate the time and expense associated with assembling, cleaning, and validating stainless steel housings. The capsule patented design allows unparalleled thermal and hydraulic stress resistance, resulting in reliability, high confidence in the sterility process and improved cleanliness. The unique capsule design with pleated Durapore membrane minimizes hold-up volume and reduces production losses.

Opticap XL 4, 5 and 10 capsule filters with hydrophilic Durapore membrane are available in multiple filtration areas, providing an optimal choice for every application.

Opticap XLT 10, 20 and 30 T-line Capsule Filters with hydrophilic Durapore membrane accommodate series or parallel filtration to match your application needs, and a specially-designed stand enables quick and easy integration into your existing process.
