Porcelain Spot Plates
Manufacturer: United Scientific
Description
Crafted from high-purity laboratory porcelain, each plate is finished with an exceptionally brilliant white glaze across its top surface and internal well cavities (leaving only the bottom base unglazed for benchtop stability). This ultra-white background provides a neutral, high-contrast field that allows technicians to detect even subtle color changes or faint precipitate formations. With elite thermal shock limits and universal chemical resistance, these plates present a rugged, reusable alternative to disposable plastic microplates.
Key Functional Benefits:
- High-Contrast Chromatic Visibility: The brilliant white glazed finish eliminates visual background interference, ensuring accurate observation of color-dependent endpoints and chemical reactions
- Outstanding Thermal Shock Resistance: Features an incredibly low average coefficient of expansion (3.56 x 10-5 from 20°C to 200°C), meaning these plates can safely withstand exothermic reaction heat without cracking
- Grease & Acid Resistant Glaze: The chemical-resistant glaze prevents sample cross-contamination, does not soften at temperatures up to 1000°C, and allows for rapid, residue-free acid washing between runs
- Efficient Sample Isolation: Concave wells are deep enough (6.5 mm) to isolate individual micro-reactions, preventing droplet migration and accidental splashing between adjacent wells
