Description
Milligard® filters provide the finest prefiltration available. Milligard® filters are constructed of homogeneous polymers of cellulose esters on a polyester web resulting in a versatile filter with high reproducibility and efficacy due to the highly retentive, non-fiber releasing membrane. The homogenous cellulose ester membrane provides the high retention needed during critical prefiltration steps while protecting more expensive downstream filtration devices from premature plugging.
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 Milligard membrane minimizes hold-up volume and reduces production losses.
Regulatory Compliance
Milligard® filters 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 Opticap® XL and XLT capsule is supported by a Validation Guide for compliance with regulatory requirements.
For traceability and easy identification, each filter is marked with identifying characteristics.
Multiple Format
Opticap® XL 2, 4, 5 and 10 capsule filters with Milligard® media are available in multiple filtration areas, providing an optimal choice for every application.
Opticap® XLT 10, 20 and 30 T-line Capsule Filters with Milligard® media are available with or without a pressure gauge port for ease in monitoring process conditions. The T-line design accommodates series or parallel filtration to match your application needs, and a specially-designed stand enables quick and easy integration of the Opticap® XLT into your existing process.
Typical Applications
Cell Culture Media
Effectively remove particles and colloidal contaminants without obstructing the flow of vital media constituents. Milligard® prefilters provide the high flow rates and consistently high throughput required to accomplish the separation in a timely and cost-effective manner.
Final Aseptic Fill of Small Volume Parenterals (SVP)
Extend the service life of downstream sterilizing filters by removing colloidal and particulate contaminants.
Large Volume Parenterals (LVP)
Extend the service life of downstream sterilizing filters by removing colloidal and particulate contaminants. Extremely robust and able to withstand high operating pressures, Milligard® filters offer dependable retention and high flow rates needed for high volume manufacturing.
Plasma Proteins—Human Albumin
Remove colloids, aggregated and non-product proteins, lipids and particles prior to downstream purification without retaining the fractions of interest. Milligard® filters provide superior protection of downstream sterile filters and/or chromatography columns.
Serum
Effectively remove lipids, colloids, and particles from serum before the final sterilizing filtration without obstructing the passage of serum proteins. Milligard® filters provide high flow rates and consistently high throughput.
