Porvair Sciences Signum™ HB, 96 Round well, F-Bottom, Black, 350 µl 205003-HB

Signum™ HB is a 96-well polystyrene assay plate with round wells and a solid F-bottom, designed for laboratory applications including cell culture, ELISA and imaging. The plate provides opaque black walls to prevent well-to-well crosstalk and a clear F-bottom allowing direct microscopic viewing and compatibility with top or bottom reading instruments. It is manufactured to ANSI/SLAS footprint with alphanumeric well coding and LOT traceability for laboratory workflows.

Key Features:

• Plate format: 96 wells, round well shape
• Well volume: 350 µL
• Bottom type: Solid F-bottom (clear PS F-bottom)
• Colour: Black with opaque walls and clear plate bottom
• Material: Ultra-pure grade polystyrene; ANSI/SLAS footprint with alphanumeric well coding
• Temperature resistance: -196 °C to +60 °C
• Sealable with adhesive films and heat seals; thickness of bottom 0.4 mm

Advantages:

• Opaque black walls reduce well-to-well crosstalk for improved assay signal fidelity
• Clear F-bottom and 0.4 mm bottom thickness permit direct microscopic imaging and use with top or bottom readers
• Manufactured to ANSI/SLAS dimensions with alphanumeric coding and LOT traceability for automation compatibility and sample tracking
• Wide temperature tolerance supports storage and assay workflows from cryogenic to moderate heating conditions
