Alkali Scientific EDTA 0.5M Solution pH 8.0, 500 Milliliters
EDTA (Ethylenediaminetetraacetic Acid) 0.5M solution at pH 8.0 is a potent chelating agent used in molecular biology and biochemistry to bind metal ions that could catalyze the degradation of nucleic acids or proteins. This 500mL solution is typically used in large-scale applications like DNA extraction, RNA stabilization, and protein purification, where controlling metal ion presence is crucial for preserving sample integrity. The 0.5M concentration and pH 8.0 provide optimal conditions for the stability of biological samples during storage and processing. EDTA is also used in laboratory buffers and reagents for routine biochemical assays, ensuring accurate, reproducible results in various experimental protocols.

Electron Microscopy Sciences MXS Calibration Standard 701CE for SEM Mounted, 700 nm Spacing
EMS offers a series of calibration standards with one and two dimension calibrated patterns. These standards are created utilizing holographic interference of a particular laser frequency. They are typically accurate to <1% across the entire surface of the standard. These reference standards are remarkably durable under typical operating conditions. The surface contamination behavior is also very good. There are no better sub-micron reference standard available in this price range. For SEM
Mount: Mounted
Spacing: 700 nm
Structure: Parallel Ridges
Material: W-coated Photoresist on Si
