Groomed for use with Beckman centrifuges, Meller Optics’ line of sapphire UV cell windows promise simplify field replacement. Notably, they are reportedly impervious to most acids, alkalis, plasma, and body fluids, making them viable for use where chemical-, scratch-and high-pressure resistance are required. In addition to Beckman centrifuges, the cell windows work well with similar instruments. They feature a scribed arrow on their edges to project the optic axis and simplify installation alignment.
Meller Sapphire Centrifuge Windows measure 19.03 mm in diameter and ±0.03 mm x 5 mm thick ±0.10 mm. They are offered wedged one or two degrees and plano; with chamfers 0.35 mm x 45 degrees in two places, and have a 30-5 scratch-dig surface finish. For less demanding applications, windows made from quartz are offered with a 10-5 scratch-dig surface finish and a 16.00 mm central clear aperture. Pricing is available upon request.
