Test Tube Holder/Drying Rack

A rack for aquarium test tubes that would double as both display (when testing aquarium water quality), storage, and drainage/drying. Small feet and holes at the bottom of each tube slot allow for drainage/drying. A line indicates 5ml, when using API test tubes or similar, which is usually the volume needed for testing. If printed on white, the semi-circular slot means the test tube has an even background colour, ideal for comparing to test colour charts. You can choose which size diameter tubes the rack can hold. Dimensions: L 5.75” , W 2”, H 3” (diameter 0.5"). Dimensions are 2.5x larger for the 1.25" diameter.
