Multi-Tier Universal Tube Racks  (aka Step Racks)

The highest row can accommodate five 30 or 50 ml centrifuge tubes in either the conical or freestanding configuration. The second row can hold eight 15 ml centrifuge tubes. The third row has ten holes for 12 × 75 mm tubes. The front row has 12 holes for microcentrifuge tubes.

Specially designed for applications where space is limited but multiple size racks are required. Made of a heavy-duty high impact polymer, this rack is truly versatile.
