From test tubes and racks to the labels and boxes you’ll use them with. MIDSCI has got your needs covered.
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).

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.
