Microscopy and staining reagents

VWR offers a broad line of reagent droppers, diagnostic kits, and antigens and antisera, for aid in identifying a variety of microscopic organisms. The visualization of bacteria by means of staining procedures is an important tool for any microbiologist to have at their disposal, and these carefully standardized and reproducible stain reagents help to ensure accurate and easily interpretable results. Stains are also available to provide early detection of positive blood cultures by fluorescence procedures.
