Porvair Sciences Signum™ MB, 384 square well, Black, 120 µl 223003-MB

Signum™ MB 384-well square assay plate is a black polystyrene microplate with a 120 µl working volume per well designed for laboratory assays and high-throughput workflows. The plate features F-bottom wells with opaque walls to reduce well-to-well crosstalk while a clear or solid F-bottom permits use with top or bottom reading instruments. It is manufactured to ANSI/SLAS footprint and produced under ISO 9001 guidelines for traceability and automated-system compatibility.

Key Features:

• Format: 384 wells, square well array
• Well working volume: 120 µl per well
• Material: Ultra pure polystyrene, medium binding surface (MB)
• Colour: Black with opaque walls to minimise fluorescence background
• Bottom type: F-bottom (solid/clear depending on variant); bottom thickness ~0.40 mm
• Standards: ANSI/SLAS footprint; temperature resistance –196 °C to +60 °C

Advantages:

• Low background fluorescence and reduced light scattering due to black, opaque well walls, improving assay signal-to-noise for fluorescence and luminescence measurements
• Designed for automation and consistent plate handling through ANSI/SLAS footprint and uniform external dimensions
• Medium binding polystyrene surface supports passive adsorption of proteins (suitable for immunoassays) while requiring minimal blocking
• Traceable manufacture under ISO 9001 with tight specification levels and low extractables for reliable assay performance
