Its removal ratings of typical bacteria in the industry have been verified by batches, and its sterilization ability LRV＞7. FSG series capsule filter is available in a wide range of cages and connections, and can provide double-layer PTFE filter membrane. The double-layer filter membrane can provide a longer service life with reliable sterilization ability of the filter cartridge through special design. It is widely used in food and beverage and bio-pharmacy.

Hollow Fiber Filters

CleaSep hollow fiber filters are currently available in 17 different dimensions, suitable for R&D, pilot testing and commercial production. The filters demonstrate stable performance with reliable linear scalability when maintaining identical length but varying surface areas. Their material composition exhibits excellent chemical compatibility with various cleaning agents, ensuring safe and effective cleaning and disinfection of the filtration system. Compared to traditional PES, the modified PES membrane not only delivers higher flow rates, greater filtration capacities, shorter processing times and improved yields, but also features low protein-binding, low-blockage and easy-clean characteristics. The modification technology optimizes PES rigidity while enhancing membrane flexibility, enabling tolerance to higher process disturbances and shear rates.

Filter Vial

MS Compure series filter vial combines syringe filter and vial technology into one simple product. Save time and money in the sample preparation process. The single-step filtering process is efficient, simple to use, easy to press, and fast. MS? Filter vial is a one-step sample preparation device and integrates a device auto-sampler, filtration membrane, plug, and cap/septa. These special filters do the filtering for you—giving you one less step in your workflow.

MS Phenolic resin Filter Cartridge

Due to its unique integrated molding manufacturing process, phenolic resin filter has the characteristics of rigidity, resin reinforcement and gradual tightening structure, thereby avoiding the shortcomings of other flexible and easily deformed filter elements.

UltraMem Nuggets cassettes are composed of UltraMem high performance UF membranes. It is a high performance tangential flow filter product with safety, convenience and cost efficiency for bio-pharm and bio-tech process.Typical applications of UltraMem Nugget cassettes include but no limited to the concentration and separation of monoclonal antibiotics, recombinant protein drugs, virus-vectors, vaccines, plasmid, mRNA LNP, particulate dispersions, cell culture clarications, buffer exchange, etc.

MS Hydrophobic PES Membrane

Membrane Solutions Hydrophobic PES Membrane is prepared by hydrophobic modification process of sterilizing grade PES hydrophilic membrane, which is specially designed for rapid air filtration or sterilization ventilation, and it can also prevent liquid penetration or condensate clogging. Compared to traditional gas filtration media, PES hydrophobic membranes are resistant to Gamma irradiation and have virtually no change in mechanical properties after high-dose irradiation, making them particularly suitable for air sterilization applications that require irradiation sterilization.

MS Hydrophilic Pure Nylon Membrane

Nylon membrane is one of the most widely used membranes in the pre-treatment stage of sample chemical analysis. Nylon membranes on the market are mainly sandwich coated with a support layer, including Memmbrane Solutions Nylon membrane. Now, Membrane Solutions has also developed a kind of pure Nylon membrane, which is composed of pure nylon 6 without a support layer. It overcomes the leaching problem caused by the support layer of traditional Nylon membranes in chromatographic applications, while also possessing the good chemical stability and solvent tolerance(including DMSO) of traditional nyon membranes. It can effectively filter aqueous solutions, dilute acid-base solutions, and most organic solvents, and is used for the removal and detection of particles, bacteria, colloids, microorganisms, foreign imimpurities, etc.In addition, the pore structure of Pure Nylon membrane belongs to an asymmetric structure with high porosity, which gives it higher flow rate and pollutant absorption performance, makong it suitable for pre-filtration of viscous and high particle content samples.

Centrifugal Filter

RevoSeizer Centrifugal Filter device can quickly and effectively concentrate and purify biological samples, and currently offers specifications of 0.5ml, 4ml, and 15ml. The unique vertical design and maximum filtration area provide fast sample processing and high sample recovery rate (typically greater than 90% of dilute starting solution), while maintaining a gentle concentration environment to preserve protein activity and conformation. Solute polarization and subsequent fouling of the membrane are minimized by the vertical design, and a physical deadstop in the filter device prevents spinning to dryness and potential sample loss. The wide selection of ultrafiltration molecular weight cut-off (MWCO) devices incorporate PES membrane, which is very low in protein and nucleic acid binding.
