Collection: Microplates & Sealing

Black plates such as Greiner's FLUOTRAC line absorb stray light, reducing background and well-to-well crosstalk in fluorescence assays. White LUMITRAC plates reflect emitted photons to maximize signal in luminescence readouts. Clear polystyrene remains the choice for absorbance and general-purpose work.

µClear plates combine black or white walls with a thin transparent film bottom, enabling bottom-reading fluorescence and cell imaging while keeping optical crosstalk low. They are the standard format for cell-based assays read from below the plate.

Yes — UV-Star plates have a cycloolefin film bottom with an optical window down to about 230 nm, so A260/A280 readings work without quartz cuvettes. They are also free of detectable DNase, RNase, and human DNA, which suits nucleic-acid quantification.

Greiner's MICROLON polystyrene surfaces come in medium- and high-binding grades; high binding is hydrophilically treated for maximum protein adsorption and is the usual choice for antibody coating. Where nonspecific binding hurts sensitivity, or for reagent storage, non-binding chimney-well plates minimize adsorption of proteins, DNA, and RNA.

Adhesive films (EASYseal, VIEWseal, AMPLIseal, SILVERseal) give a tight evaporation barrier for PCR, storage, and optical reads, with acrylate or silicone adhesives matched to the application. EVA CapMats seal 96-well formats such as MASTERBLOCK deep-well plates, resist DMSO, and work from -20 °C to +60 °C, though they are not pierceable. Low-profile lids cover plates during short-term handling and incubation.

Greiner Bio-One assay plates and sealing products are stocked in Israel by Danyel Biotech, the brand's official local distributor — from single cases to screening-campaign volumes, with application advice and fast quotes.
