Alkali Scientific EDTA 0.5M Solution pH 8.0, 250 Milliliters
EDTA (Ethylenediaminetetraacetic Acid) 0.5M solution at pH 8.0 is a widely used chelating agent in molecular biology and chemistry for binding metal ions that could otherwise interfere with biochemical reactions. This 250mL solution is ideal for larger-scale laboratory applications, such as DNA extraction, protein purification, and enzymatic assays, where metal ion inhibition is crucial. EDTA works by sequestering metal ions like magnesium and calcium, which are essential cofactors for many enzymes, thereby preventing unwanted enzymatic activity. This reagent is commonly used in molecular cloning, gel electrophoresis, and sample preparation for analysis, ensuring consistent results in nucleic acid and protein-related studies.

Electron Microscopy Sciences MXS Calibration Standard 701CE for SEM Unmounted, 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: Unmounted
Spacing: 700 nm
Structure: Parallel Ridges
Material: W-coated Photoresist on Si
