Modular systems for filing slides and paraffinembedded preparations. The Istoglass modules (for slides) and Istobloc modules (for cassettes) are made entirely of white enameled metal.
They consist of sliding drawers fitted on guides. Each block of Istoglass/Istobloc modules requires completion with a base and top. The special 7-drawer version for large slides
or super mega cassettes retains the same modular form. The spacer spring is recommended for keeping the slides in a vertical position with the correct spacing between them.
