Filtration is a critical and one of the most commonly used steps in biopharmaceutical processing. Therefore, the small-scale device filter material used for process development must also be available in a device format designed for commercial production.


Streamlining Large Scale Filtration

The Maxicaps® MR is a large-scale filter device that utilizes a unique filter capsule connection concept and integrated valves. The standardized design is compact and easy to use, while the wide range of options for filter types and configurations allows the Maxicaps® MR to be easily integrated into different process steps requiring large filter areas.


Clarification of Vaccines and Viral Vectors

Clarification of vaccines and viral vectors is a critical step that has a significant impact on product recovery and subsequent downstream purification. The main challenge is to recover a high yield while efficiently removing cell debris, large aggregates, and insoluble contaminants. The Maxicaps® MR is a perfect fit for these applications due to the closed system design and the large effective filter area starting from 50 L bioreactor batch volume.


For Bioburden Reduction and Particulate Reduction

Prefilters are critical in the overall filtration strategy. They protect downstream filters and processes, remove particulates, and reduce microbial levels. Prefilters can also be used as guard filters to protect high-value chromatography steps.  
Selecting the best design for the large-scale filtration device is a crucial step in ensuring the quality and safety of biopharmaceutical products. With the flexibility to configure the Maxicaps® MR with a range of Sartorius filter types and the amount of filter area needed, Maxicaps® MR provides an easy-to-use solution specifically designed for your large-scale filtration needs.

Sartorius’ well-known membrane filters, Sartopore® 2 and Sartopore® Platinum, are available in the Maxicaps® MR format and are suitable for any large-volume media and downstream intermediates sterilizing-grade filtration.

Filter integrity testing of complex filter assemblies poses a challenge as each filter element must be tested individually. With its novel integrated valve and connection technology, the Maxicaps® MR can be integrity tested as one unit, significantly reducing the complexity and testing time.

Mycoplasma Filtration

Efficient Removal of Mycoplasma

Mycoplasma contamination – carried into the process by the culture media due to a contaminated raw material - can negatively impact the quality of the final product if not treated appropriately. Mycoplasma filtration of media mitigates contamination risks, preventing costly batch losses.

Maxicaps® MR with Sartopore® XLM filters is a single-use solution designed for large-scale media filtration that can effectively remove mycoplasma from biopharmaceutical fluids. This plug-and-play system can help ensure the quality and safety of biopharmaceutical products by reducing the risk of mycoplasma contamination.

Virus Pre-Filtration

Next Level Virus Filter Protection

Our virus prefilter - the Virosart® Max – uses patented technology to protect the valuable virus filter. It combines a size exclusion mechanism with efficient adsorptive capacities to increase the robustness of the subsequent virus filtration step. The most challenging molecules for the final virus retentive membrane are aggregates and | or small hydrophobic molecules. Virosart® Max binds aggregates very efficiently through hydrophobic interactions, independently of process conditions such as conductivity.

Large Scale Filtration Solutions

Risk Reduction and Time Savings with Integrated Connection and  Valve Technologies

Stainless steel multi-round housings are commonly used in conventional large-scale filtration processes. While filter assemblies with multiple components and connections provide a single-use alternative, these systems are complex and tedious to operate. Systems with many connections and components can produce supply chain challenges, increase operator time and effort, contribute to leakage risk, and add to transportation and storage costs.  
Maxicaps® MR represents a paradigm shift in large-scale single-use filtration, offering a standardized solution that saves time and mitigates risk due to its simple design and operation.

Bioprocess filtration refers to the process of filtering a large volume of bioprocess materials to remove impurities. Depending on the process step, the volume can range from 50 L (clarification in viral vector processes) to several thousand liters in media and buffer filtration.

Typical large-scale filtration systems are multiround catridges in stainless steel housings or single-use filter assemblies.

Large scale filter validation follows the same prinicples as smaller filters. However, large filtration areas typically involve more complex and sophisticated equipment, which may require additional validation steps to ensure that the equipment is operating correctly.

Sterilzing grade filters are validated using a bacterial challenge test with the product solution. In addition, extractable and leachables studies, adsorption studies, chemical compatibility testing, and product specific integrity tests are carried out.

Large scale filters are tested as a unit in one test with a filter integrity test system such as Sartocheck®. Due to the use of multilpe filter elements in a single housing, there is a risk of potential masking of defective filter elements by intact filter elements. In single-use systems the risk of a defect Large scale filters are tested as a unit in one test with a filter integrity test system such as Sartocheck®. Due to the use of multilpe filter elements in a single housing, there is a risk of potential masking of defective filter elements by intact filter elements. In single-use systems the risk of a defect filter cartidge is unlikely  due to gentle sterilization conditions and manufacturer tests. cartidge is unlikely  due to gentle sterilization conditions and manufacturer tests.

Stainless steel systems suffer from a lack of flexibility due to their fixed piping and fixed location. Additionally, they require time-consuming and resource-intensive cleaning procedures.

Conventional single-use multifilter assemblies require many process and cable tie connections, creating many tubings and an untidy design, increasing the risk of operator error. Single-use setups also require multiple individual material numbers, each with its own packaging and storage space, as well as long design and lead times.

Large-scale filtration can be applied to various downstream process steps, including clarification in vaccines and viral vector processes; bioburden reduction post-clarification and in intermediate downstream steps;  capture-column guard filtration or particle reduction in vaccine, viral vector, and pDNA processes; and pre-filtration to protect the final virus retentive filter.

High-quality filtration techniques can significantly impact the purity and potency of the product, resulting in a cleaner, more effective biologic that meets regulatory standards. Proper filtration ensures the products manufactured are safe for patients and mitigates commercial risks. However, it is essential to note that the precise impact of large-scale filtration on product quality may vary depending on the specific product and the filtration method used.

Single-use filtration systems avoid high capital investment in equipment and factory infrastructure, as well as costly clean-in-place and steam-in-place procedures. They are also an economical choice for a contract manufacturing organization (CMO) or any facility that requires agile solutions. In addition, single-use filtration systems are readily available and do not require cleaning validation, which can shorten project timelines.

Large-scale filtration is employed in upstream processes for media and buffer preparation (mycoplasma removal and sterilizing-grade filtration) and clarification. In downstream process steps, large-scale filtration is used for bioburden reduction, capture-column guard filtration, particle reduction, and pre-filtration.
