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.

ASAVANTTUBES1

New sterile microtubes from MIDSCI are manufactured under clean room conditions, using only BioClear co-polymer, an advanced polypropylene that maximizes clarity, centrifugal strength (tested up to 28,000xg) and the usable Temp Range (-90°C to +121°C).

The oversized tube cap (with frosted marking surface), combined with the unique ring & groove closure, enhances the security of the liquid-tight seal, while minimizing the required locking forces for a more ergonomic opening/closing of the tube caps.

All tubes are RNase, DNase and pyrogen free.

  • Self-Standing bag - with gusseted bottom
  • Stop-Pops supplied - 10 cap locks in every bag

  • Attached flat snap caps
  • Molded graduations
  • Writing surface
  • Centrifuging to 25,000 x G
  • Autoclavable (122°C) and freezable (-80°C)

The interior surfaces are ultra-smooth with low retention characteristics. Lab testing confirms the superior performance of SuperClear® tubes in light transmission compared to other brands. SuperClear® tubes are more than twice as effective at transmitting light than other brands of 5 mL centrifuge tubes.

SuperClear® 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.
