Test Tubes and Racks
From test tubes and racks to the labels and boxes you’ll use them with. MIDSCI has got your needs covered.
MIDSCI has a wide assortment of test tubes, including top-notch centrifuge tubes your research depends on. We carry everything from sterile centrifuge tubes that we promise won’t buckle during spins to specialty centrifuge tubes that are completely blacked out to preserve your light sensitive compounds.
We also have freezer racks and autoclavable racks, stackable storage boxes and freezer boxes, general storage containers and cryogenic storage refrigerators and tanks.
And let’s not forget the labels! Wash-off labels, removable labels, and labels that will never come off (if you need that).
There are so many other quality choices and options for all of these products.

Or, rotate it another 1/2 turn past the second click for a leakproof, airtight seal for anaerobic culturing.
