EM Fixatives

Polysciences’ EM Fixatives collection includes a variety of solutions such as methanol-free formaldehyde-based fixatives (e.g. Poly/LEM), neutral buffered 2% paraformaldehyde (Flow Fix), modified Davidson’s fixative (Hartmann’s), Hollande’s, and fixatives that decalcify while fixing (e.g. Poly-NoCal & Fixative). These reagents are formulated to preserve ultrastructure and tissue morphology for both light and electron microscopy.
