Falcon and Eppendorf Tube Rack

This is a tube rack to snugly secure 15mL and 50mL falcon tubes; 5mL, 1.5mL, and 0.5mL eppendorf tubes.
The combination tube racks you can order were just too expensive for what they were and some did not secure the tube enough for my liking. This rack solves that. Enjoy!
