Small Spray Dryer Fits In Laboratory Hoods


The Model 0.1 PolarDry electrostatic spray dryer has a design that follows current good manufacturing practices (cGMPs) enforced by the U.S. Food and Drug Administration (FDA). The dryer is compact, but can be easily disassembled for autoclave sterilization. The small dimensions allow the dryer to fit inside most lab fume or containment hoods to safely test systems containing toxic solvents, potent active pharmaceutical ingredients (APIs), and oxygen-sensitive materials. It is compatible with optional high-temperature and ultrasonic spray drying nozzles to improve overall microencapsulation; the ultrasonic nozzle is particularly suited for creating small particles of less than 10 μm. The dryer uses nitrogen as both the drying and atomizing gas (with flowrates up to 8.5 m3/hr and 3 m3/hr, respectively), so there is no need for atomizing heat, which reduces volatility losses. The dryer has a tabletop nominal evaporation rate of 0.1 kg/hr and operates between 20°C and 200°C. It features a 0.25-L collection volume, once-through gas handling, a feedstock pump, and a filter bag. The batch architect software controls are NEMA 4X-rated.

Rubber-Like Polymer Boasts Stable Properties


Levapren PXL is an ethylene-vinyl acetate rubber-like polymer with a methylene backbone. It is available with a vinyl acetate content ranging from 50% to 80%. The fully saturated main chain is particularly stable, and degradation generally occurs only at very high temperatures, and even then, very slowly. It has a high viscosity, is easy to process, and can be used to manufacture high-quality hoses, cable sheathings, and floor coverings. The material is fabricated by reactive extrusion, which requires less peroxide than fabrication with radiation-induced precrosslinking. Extrusion also ensures that no trace of the crosslinker is left in the finished product. The polymer is a free-flowing granulate that does not adhere well to metal, which is beneficial when processing materials in mixers and on rolling mills. The material is hot-oil- and fuel-resistant, shows no outdoor weathering effects after two years of testing, and has fire-retardant properties.
