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.
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. 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.

SuperSpin® microcentrifuge tubes were designed with the ability to extract DNA from samples and then amplify that DNA with reliable results in mind. They can be trusted to spin at high rates and can be opened and closed easily many times to add or remove agents. The interior surfaces are ultra-smooth with low retention. The tubes are clear enough to be use in spectrophotometers and have no extractables at the wavelength ranges you use to detect DNA. SuperSpin® microcentrifuge tubes are more than twice as effective at transmitting light than most brands of micro centrifuge tubes.
*Maximum G-force can be affected by organic solvents, multiple spin cycles, or low temperature storage.

Autoclave Tape:
Autoclave tape is used as a process indicator in steam sterilizers. It features an aggressive, pressure-sensitive adhesive designed to adhere to a variety of wraps so that the pack stays secure during sterilization and can be used on direct contact with substrates. Tape also features a chemical indicator to verify that it has gone through the sterilization process. Black diagonal lines appear on the tape after 10 minutes at 121°C or 2 minutes at 134°C in a steam sterilizer.
Core size: 3" Core
Size: ¾" wide x 60 Yard or 1" Wide x 60 yards
Lead Free Autoclave Tape:
Sterilization package sealing tape with a process indicator. Designed for gravity sterilizers at 121°C for 30 minutes and pre-vacuum steam sterilizers at 132°C for 3 minutes and 135°C for 3 minutes.
