Questions about this item

Will the 1.63 in H Zoro Select 21RK91 cassettes fit the standard microtome chucks I already use?

The cassettes measure 1.63 in H, matching the common height used in most routine histology microtome chucks.

How can I confirm the 21RK91 cassettes are correctly seated after loading a tissue block?

The white plastic body clicks into the chuck and the lid snaps flush, giving a visible and tactile indication of secure placement.

Does the pack of 500 include lids or do I need to order them separately?

Each of the 500 cassettes is supplied with its matching lid attached, so no separate lid purchase is required.
