A rack for centrifuge tubes is disclosed including a plurality of receptacles sized to snugly receive one of a variety of different diameter centrifuge tubes. The rack may be formed of a variety of biodegradable, compostable materials, including for example molded polypropylene or organic resins such as a corn-based resin or potato-based resin. The rack further includes a lattice of recesses defined within an upper surface of the rack, which recesses extend between and connect the receptacles to add rigidity to the rack and flexibility to the individual receptacles.
