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.

SUPERCLEAR® 15 & 50 ML CENTRIFUGE TUBES

  • Leak resistant flat camps with elastomeric molded-in sealing
  • Patented, extra-large writing panel shows contents in tube clearly, labels easily, and is smear resistant for permanent coding
  • Easy to read graduations and reverse scale for accurate measurements
  • MAX FREEZE indicates the maximum volume for samples that will be frozen
  • Thick, durable, medical grade resin withstands breakage and allows tubes to spin at g-forces up to 233% greater than other tubes
  • SuperClear® tubes are recyclable, are offered in reusable/recyclable racks and feature recycling codes


CLARITY
Made from an ultra-clear non-cytotoxic medical grade resin that allows you see sample volume and color easily. These tubes feature highly visible printed graduations for easy filling and sample preparation.

DURABILITY
Engineered with thick, durable walls for ultra-high-speed centrifugation. SuperClear® tubes consistently out-perform other brands.

RELIABILITY
Our patented, extra-large writing panel is the largest on the market and transparent to easily view your sample through your label. This writing panel is also smear-resistant for permanent coding and won’t wear off when inserting and removing your tube from the centrifuge rotor.

SECURITY
Leak resistant SuperClear® 15 mL and 50 mL flat caps feature a molded-in sealing ring that keeps your closed tubes completely secure. These caps are ideal for vortexing chemicals and long rocker incubations.

SUSTAINABILITY
Designed for maximum product recyclability and manufactured in a solar powered facility with unique waste-free molding machines. Tube graphics and graduations are printed with UV cured inks which significantly reduces the emissions of harmful volatile organic compounds (VOCs). Offered in reusable and recyclable racks.

15mL PP (17x118mm) Centrifuge Tubes

 Our 15mL, 30mL, and 50mL centrifuge tubes are made of premium polypropylene for clarity and centrifugal strength. Tubes and caps may be frozen at temperatures as low as -86C. The maximum centrifugal force is 12,000xg for the 15mL tubes, 7,000xg for the 30mL tubes, and 15,000xg for the 50mL tubes*. Caps have a flat top surface for easy marking and labeling. C2605 and C2630 feature a ‘skirted’ bottom that allows the tubeS to stand upright without a separate test tube rack. The C2600 series of centrifuge tubes, self-standing or not, are leakproof to 95 kPa/14psi.

*Refers to liquids with a specific gravity of 1.0, using appropriate rotors, cushions, and adapters.

  • Sterile, RNase, DNase, pyrogen and cytotoxin free
  • Available racked or bagged
  • Compatible with standard rotors
  • Frosted marking surface

LabCon SuperSpin™ Microcentrifuge Tubes

  • Ultra-high centrifuging up to 40,000 x G*
  • Optically clear resin
  • Resin will not interfere with DNA or PCR
  • For Phenol/Chloroform vortexing
  • Reduced Thumb Force
  • Autoclavable (122°C) and freezable (-80°C)
  • Packaged in resealable bags
  • Tubes have flat pierceable caps and a side writing surface
  • Graduated

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.
