What vial count should I use?

Use the usable vial positions per box, not the nominal box name, if dividers or oversized tubes reduce fit.

Can this plan accessories?

Yes. The rack and shelf counts provide a starting bill of materials for quote requests.

92% rack utilization. Add another rack or larger freezer class; capacity is too tight for routine access.

Exact fit checks without confirming the freezer interior and rack dimensions

Round up every physical layer

Boxes, racks, and shelves are discrete. Rounding down creates impossible layouts.

Reserve space is not wasted

Reserved capacity supports audits, cleanup, and temporary sample moves.

Method

Samples are divided by vials per box, then adjusted for growth and reserved empty space. Racks and shelves are rounded up from boxes per rack and racks per shelf.
