Plano-convex lenses Edmund Optics introduces TechSpec Calcium Fluoride Plano-Convex (PCX) Lenses. The lenses are suitable for use in demanding applications that require good performance from the ultraviolet (UV) through the mid-wave infrared (MWIR) spectra. Featuring a low index of refraction, high laser damage threshold and low axial and radial-stress birefringence, the lenses are suitable for use with Excimer lasers or for integration into IR systems. The lenses, manufactured using a vacuum-grade UV substrate, offer greater than 90% transmission

Pre-packed columns WR Grace & Co has introduced ProVance prepacked Protein A columns for purification of biologic drugs, specifically monoclonal antibodies (mAbs). The columns bring together Protein A resin and a convenient prepacked column format designed specifically for facilities sites that have moved to single-use manufacturing methodologies. The portfolio of disposable columns comes prepacked with a silicabased Protein A resin claimed to have a higher capacity than alternative technology used for mAb purification. Biopharmaceutical users are said to have confirmed 40 to 60% total operational cost reduction with the columns by eliminating timeconsuming cleaning and packing steps and achieving increased efficiency. The prepacked disposable columns further improve biopharmaceutical productivity by lowering the risk of contamination and accelerating time to market.
