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.

DuoClick™ Two Position Screw-Cap Culture Tubes

  • New patent pending screw-cap!
  • Aerobic culturing at first click
  • Anaerobic after second click
  • Printed graduations
  • Flat, markable screw-cap

DuoClick™ tubes feature a unique, patent pending screw closure system. DuoClick™ tubes completely eliminate the excess force, splashing and general frustration of traditional snap-cap culture tubes. The advanced cap design includes two distinct positions for aerobic and anaerobic culturing. Just rotate the cap 1/4 turn to the first click to secure the cap in the aerobic position. Or, rotate it another 1/2 turn past the second click for a leakproof, airtight seal for anaerobic culturing.

DuoClick™ tubes are available gamma sterilized, with screw caps attached, and in our exclusive ready-to- use rack packaging. Polypropylene tubes can be centrifuged at up to 4,000 x g.
