Core Business and Technology

FILTROX's core competence lies in depth filtration, a process essential for the removal of solid particles from liquids. Unlike surface filtration, depth filtration uses a porous matrix (the filter media) to capture contaminants throughout the entire volume of the material. This method is highly effective for clarifying liquids and removing particles ranging in size from approximately 0.04 to 55 microns.

The company's solutions are vital in processes where hygienic requirements are paramount, such as in the Life Sciences, Biotechnology, and Pharmaceutical sectors, as well as in the Food & Beverage, Cosmetics, and Chemical/Industrial segments. The company's expertise is leveraged to support customers from the initial lab-scale process setup through to full-scale industrial production, ensuring the quality and purity of the final product.

Products and Services

FILTROX provides a comprehensive portfolio of products, divided into filter media and filtration equipment, with a significant emphasis on high-purity, scalable, and single-use solutions for modern bioprocessing.

I. Filter Media and Modules

• PURAFIX? Filter Sheets and Modules: These are specially developed depth filter sheets characterized by high purity and extremely low extractables, making them suitable for demanding applications within the biological and pharmaceutical industries.
• FILTRODISC???/PURADISC? BIO SD: These represent a crucial innovation for the Life Sciences market. They are disposable depth filters that incorporate the advantages of alluvial filtration technology (similar to cake or precoat filtration) in a single-use format. They are designed to remove particles (like cells), impurities (e.g., Host Cell Proteins/HCP, DNA), and other turbid matter.
• PURADISC? SU Single-Use Depth Filtration: A single-use technology that utilizes the principles of alluvial filtration in a closed, disposable system. This is especially suited for high-stakes applications in biologics, gene therapy, and pharmaceutical manufacturing, providing benefits like reduced downtime, elimination of cleaning and cleaning validation, and minimization of contamination risk. Typical applications include CHO cell removal, bacterial removal, yeast removal, and plasmid DNA purification.
• ACTIVASORB? Sheets, Modules, and Caps: Depth filter products that contain immobilized activated carbon. These are used for critical processes such as decolorization, deodorization, or the removal of catalysts and other trace impurities in pharmaceutical, cosmetic, and food production.
• FIBRAFIX? AF Line: A well-established and successful generation of filter sheets used across various industries.
• SYNTHAFIX P Line: A line of filter sheets specifically engineered for the filtration of high-value pharmaceuticals derived from human blood plasma.
• CARBOFIL: Powdered activated carbons (PAC) supplied for critical decolorization and deodorization processes in various industries.

II. Filter Equipment and Housings

• DISCSTAR? BIO SD Housings: Precision-engineered stainless steel housings designed to accommodate the PURADISC? BIO SD single-use filter modules. They are often tiltable and come with a trolley for easy module transport.
• DISCSTAR H Housings: Highly precise, stainless steel filter housings for lenticular filter modules, designed as an enclosed system to facilitate drip-loss-free depth filtration.
• NOVOX? Filter Presses: A series of modular plate and frame filter systems, including the NOVOX? ST (Basic/Standard), NOVOX? OD (Gasket-free system), and NOVOX? CP (Enclosed system for closed processes).
• FILTROstar Candle Filter: One of the company???s historical product innovations, being one of the first candle filters worldwide introduced for beverage filtration.
• DISCSTAR? SU SKID: An advanced system for continuous manufacturing that enables seamless integration of the single-use alluvial filtration technology (PURADISC? SU) into bioprocessing workflows, offering significantly higher filter capacity.

III. Services

• Process Development Support: FILTROX supports the entire process, from method development to large-scale production, ensuring linear scalability of its filtration solutions.
• SCALE-UP Test Kit: A specific tool offered to assist customers in process development by allowing them to find the ideal depth filter for their application at an early stage.
• Technical Consulting: The Group offers technical support and expertise to help customers optimize their existing filtration processes for better efficiency and economy.

The FILTROX Group's focus on depth filtration, combined with its strong presence in the high-growth Life Sciences and Biopharmaceutical markets through single-use and alluvial technology, solidifies its position as a critical supplier of separation and purification solutions worldwide.
