Test Tube Holder

by GilRamirez

Test Tube Rack & Drying Rack for API Saltwater Master Test Kit & 3 Hanna Test Kits. Designed for 4 x 5 ml API test tubes, 3 x Hanna 10 ml Cuvettes, 2 x 1 ML syringe tips, 1 x 0.01 ml syringe tip. Hangs on a standard Top Fin Bow Front, or any flat aquarium. Designed with top and bottom retainers, and a lip to contain liquid spills. I designed it to hold my test kit hardware to make it easier to collect the samples, test, carry them to the sink, hang on the sink, wash the hardware, and leave in the rack to dry hanging on the back of the tank where it inconspicuous. Saves me a lot of time, and has saved me from breaking several tubes and cuvettes.
