New Microplate Designed for High-Resolution Microscopy

A new, black 96-well microplate includes an ultra-low well base that enables high-magnification microscopy, inclusive of perimeter wells, even with a minimum working distance.

Greiner Bio-One (Frickenhausen, Germany) now expands its microplate portfolio with the introduction of “ScreenStar” at the 2013 Society for Laboratory Automation and Screening (SLAS) conference exhibition in Orlando (FL, USA). The ScreenStar design includes several new features. Manufactured entirely of cycloolefin, an innovative material with glass-like optical properties, it facilitates outstanding image quality of well contents. The microplate has a 190 μm ultraclear film bottom. The key advantage of ScreenStar over other plates for high-resolution microscopy is the extremely short distance between the well bottom and the microplate skirt (internal well to skirt bottom = 0.7 mm; external well to skirt bottom = 0.51 mm), rendering ease of high magnification microscopy at perimeter wells without complex microscopic adjustments. The circular wells allow microscopic work without disruptive shadow using the smallest possible meniscus lens. The perimeter ditch can be filled with water or medium to reduce edge effect due to evaporation, especially for long incubation periods. A proven cell culture-treatment quality ensures reliable, uniform growth.


The black, 96-well, 190 μm clear film bottom, cell culture treated, cycloolefin ScreenStar microplate comes sterile with lid, individually packed. Well bottoms are protected by a film that must be removed prior to use. The identical microscopy plate with a glass bottom will be introduced shortly.
