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.

- Attached flat snap caps
- Molded graduations
- Writing surface
- Centrifuging to 25,000 x G
- Autoclavable (122°C) and freezable (-80°C)
5 mL SuperClear® snap cap centrifuge tubes are an efficient alternative to 15 mL tubes. Designed to fit the same rotors as our 15 mL centrifuge tubes, you can use these tubes in procedures that require smaller sample volumes.
The interior surfaces are ultra-smooth with low retention characteristics. Lab testing confirms the superior performance of SuperClear®Â tubes in light transmission compared to other brands. SuperClear®Â tubes are more than twice as effective at transmitting light than other brands of 5 mL centrifuge tubes.
SuperClear®Â tubes feature an extra-thick and durable wall that can withstand centrifugation to 25,000 x G, more than twice some other brands. The ultra-clear polypropylene resin gives you a clear view of the pellet as well as correct color rendition. Designed with ergonomic caps and smooth surfaces.
Tubes have flat, pierceable caps and a side writing surface and are packaged In resealable bags.

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®Â 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.
