Test Tube Racks & Supports

Scienceware® Switch-Grid™ Test Tube Racks

This innovative, split-frame test tube rack holds up to two different size tubes in the same rack and allows users to quickly switch grids to hold other sizes as needed. Each test tube rack frame includes a set of grids in one size. Grid sets in alternate sizes can be purchased as needed. Colored grid inserts correspond to a specific test tube size ranging from 10mm to 30mm in diameter. Rubber feet keep racks from sliding on benchtop, provide secure stacking while in storage. Chemical resistant polyoxymethylene plastic rack frame and grids can be cleaned with mild detergent, ethanol or isopropyl alcohol.
