Argos Technologies® Magne-Box™ freezer boxes are the first of its kind to offer a magnetic lid closure! Each box features magnets that securely connect the base to the hinged lid. This allows for one handed retrieval from freezer racks and ensures that samples stay safe. Polycarbonate boxes have clear lids with colored inserts and numbered grids to facilitate easy sample identification. Available with 25-, 81-, and 100-place divisions.
