At Sartorius, we know providing quality lab filtration materials is only half the battle. If a filter isn't easy to put in place, connect or use, it becomes a problem rather than a solution.

Ultrafilter membrane discs for sample concentration in stirred cells, available in three different materials: Polyethersulfone (PES) with high flux, no hydrophobic or hydrophilic interactions and low fouling characteristics, cellulosetriacetate (CTA) for high hydrophilicity and high ultrafiltrate recovery and Hydrosart® regenerated cellulose with extremely low protein binding and extended chemical resistance. Our ultrafilter m…

Disposable capsules with ion exchange membranes for polishing in biomanufacturing. The capsules are especially suited for the removal of DNA, viruses and protein contaminants. Our membrane adsorbers feature extremely short cycle times and provide exceptionally high flow rates and throughput thus they increase the process speed and avoid diffusion limits compared to conventional bead chromatography. • Simple handling • High spe…

Ready-to-use syringe filter units for ion exchange chromatography. Typical applications are the separation and purification of proteins. The units combine the advantages of Sartobind Membrane Adsorbers for ion exchange chromatography and syringe filter design and thus allow for rapid and easy handling of samples. • Ready-to-use devices • Simple handling with syringe or pump • High binding capacity • Very high flow rate • Robus…

UniSart® nitrocellulose membranes have been designed to be the ideal solid phase for Lateral Flow, able to bind high amount of capture reagent and yield a controlled and fast wicking of samples. Developed in the mid–80 for pregnancy testing, more than a billion Lateral Flow Immunoassays are today produced per year. Many markers such as cardiac, cancer, drug abuse and more can be analysed on such a strip. Like an ELISA it uses…

Being the first ever manufacturer of microporous membranes, Sartorius has many decades of experience in membrane formulation as well as in the building of state of the art specific casting machines. In the recently upgraded and enlarged manufacturing site in Germany, we have rigid environmental controls in place to provide a clean and stable manufacturing process. From the large portfolio of microporous membranes and ultrafilt…

Protein microarrays (or biochips) are indispensable tools for many proteomic applications and new multi-parameter IVD tests. The UniSart® 3D Nitro slides have been designed to be the best substrate for protein array applications, e.g., direct protein arrays (forward capture protein or antibody assays) and reverse phase protein microarrays (or lysate arrays). The multiplicity of protein spots, displayed on the slide surface, pe…

Line or dot immuno strips are still widely used in IVD tests. Many infectious diseases generate indeed a complex immune response and necessitate checking the patient serum for the presence of several antibodies. Today, the self wetting nitrocellulose membrane is still the best uniform substrate for the binding of these different immuno-dominant antigen proteins. The UniSart® 0.22 μm and 0.45 μm nitrocellulose membranes have be…

The Biosart® 100 Monitors have been specifically designed for the detection and enumeration of microorganisms in pharmaceuticals, cosmetics, food, beverages, water and other liquids. The monitors are sterile funnels, ready-to-use due to the incorporated membrane filter and cellulose pad. After filtration, just remove the 100 ml funnel to convert the monitor into a petri dish, eliminating the need of membrane manipulation.

Sterisart® universal pump for sample and media transfer into the Sterisart® NF systems for sterility tests. The peristaltic pump can be used in clean rooms, integrated into clean benches, or installed countersunk in the working surface of isolators. Sterisart® universal pump is available as an upgraded version with display and user software. The sterility test system features a compact design with a space-saving footprint -…
