UNIBAG Series filter bags are made from low-cost, environmentally friendly materials and provide excellent retention efficiency, operational integrity and reliability. They are available in both polypropylene and polyester made from recycled fibers with no optical white additives. The top UNIRING, which features a molded seal, provides optimum sealing and eliminates bypass problems common with snap rings. This design also reduces process system contamination caused by debris passing through needle punch holes.

The APEX dry separation screener is a self-contained screening machine that minimizes process downtime and reduces operating costs. Its ergonomic features allow quick and easy maintenance, cleaning and inspection and reduce operator effort, resulting in labor savings and improved operating efficiency. Side access doors and a patented lift cam system provide easy access to screens and ball trays. Screen installation and inspection can be completed in less than two minutes for each panel.

The Centri-Sifter twin ultra-high-capacity centrifugal screener provides the performance of two individual high-capacity screeners, but with a smaller footprint. It handles either dry or moist bulk-solid materials, which are gravity-fed through a splitter that evenly divides the incoming flow into two horizontally oriented cylindrical screening chambers operating in parallel. A shaft in each screening chamber rotates a helical paddle assembly that accelerates the radial movement of particles against the screen.

This granulizing-drying system consists of a centrifugal screener, a spheroidizer, a circulating fluid-bed dryer, and a vibratory screener. Non-flowing moist solids that have been discharged from cartridge and vacuum filters, filter presses, mixers or other equipment are converted into uniform, compact, dry, de-dusted, free-flowing granules that can be stored, shipped, packaged or put through secondary processing.

The stainless steel Tru-Balance sifter is available in three high-capacity models, each using gentle gyratory motion and the manufacturer’s reliable Tru-Balance drive mechanism. Its stacked-screen construction conserves floor space, allows for highly efficient material grading, reduces chances of screen sagging, and enables the sifter to be suspended or floor-mounted. The pneumatic sieve-compression system simplifies cleaning and maintenance, making it suitable for use as a sanitary gravity flow, atmospheric pressure sifter or screener.

Designed to provide flexibility and high performance, Mustang Q XT series reusable chromatography capsules help process development engineers reduce purification time, increase throughput, and cut buffer consumption costs in ion exchange applications. They are available in 5-mL, 140-mL and 5-L sizes, and units can be linked in parallel or in series to increase processing capabilities. Each capsule has 16 layers of the Mustang Q membrane.

The Mupor polytetrafluoroethylene (PTFE) microporous membrane features a three-dimensional pore structure that helps to keep the pores from collapsing under pressure, and comes in a wide range of pore sizes, from 0.5 mm to 50 mm. It is supplied on rolls, with or without an adhesive backing, and can be ordered in thicknesses from 50 mm to 3,000 mm and in widths up to 330 mm. The membrane has a tensile strength up to 20 N/mm2 and is U.S. Pharmacopeia-approved (USP-23) and non-cytotoxic.

Constructed of polyvinylidene fluoride (PVDF), all-plastic Fluor-O-Shield basket strainers cost less than units that are lined with steel or other metals, and outperform ordinary plastic strainers made from polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polypropylene and acetal materials. Unlike previously available plastic strainers, these can handle corrosive materials, including halogens and many acids, and they can operate at temperatures up to 300°F.

PureProteome magnetic nickel beads form a powerful separation matrix with high binding capacity that can be used for the fast and easy purification of polyhistidine-tagged recombinant proteins. A patented process creates high-affinity beads, which offer higher purity while yielding similar amounts of protein compared to other less-pure magnetic beads. These beads bind recombinant protein even in the presence of ethylenediaminetetraacetic acid (EDTA), which is a metal ion chelator.

The Centri-Sifter MO-SS centrifugal screener has a hinged end cover and a three-bearing cantilevered shaft to ease internal component removal. External roller bearings are located at the motor end of the shaft and on a hinged cover at the discharge end for maximum support and vibration-free operation. When the end cover is opened, the shaft becomes a cantilever supported by a third externally mounted roller bearing located between the motor-end bearing and the material feed point. This design allows internal components to slide freely from the opposite shaft end for a thorough washdown.
