Polysep™ II Capsule Filters

Opticap XL and XLT capsule filters eliminate the time and expense associated with assembling, cleaning, and validating stainless steel housings.

Overview

Description

Polysep™ II filters are ideal for a broad range of aqueous-based applications. The Polysep II media consists of a borosilicate glass layer and a layer of mixed esters of cellulose membrane. The depth of the microfiber filter layer provides high particle loading capacity, and retention of large particulates while maintaining high flow rates. The mixed cellulose ester membrane layer provides the high retention needed during critical prefiltration steps while protecting more expensive downstream filtration devices and equipment.

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 Polysep II media minimizes hold-up volume and reduces production losses.

Regulatory Compliance

Polysep II 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 Polysep II 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 Polysep II 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

Buffer Preparation
Reduce particulate contamination and bioburden before final sterilizing filtration and provide excellent protection for sterilizing grade membrane filters in applications requiring more extensive buffer prefiltration.
Cell Culture Media
Polysep II prefilters effectively remove particles including lipids, and colloidal contaminants without obstructing the flow of vital media constituents.
Large Volume Parenterals (LVP)
Extend the service life of downstream sterilizing filters by removing colloidal and partiulate contaminants. The robust design withstands high differential and operating pressures, high flow rates and multiple steam-in-place or hot water sanitization cycles.
Ophthalmics
Polysep II prefilters reduce particle and bioburden before sterilizing filtration and will withstand process variability.
Serum
Polysep II prefilters remove lipids, colloids, and particles from serum before final sterilizing filtration without obstructing the passage of serum proteins.
