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.

SuperSlik® Microcentrifuge Tubes

  • High centrifuging to 20,000 x G
  • Freezable (-80°C)
  • Autoclavable
  • Capacity: 1.5 mL
  • ATP, RNase/DNase and Endotoxin Free (non-pyrogenic)
  • Attached flat snap caps

SuperSlik® low retention microcentrifuge tubes have a low protein binding surface that minimizes sample loss during sample manipulation.  Ideal for applications such as mass spectrometry (ms), immunoprecipitation (IP), co-immunoprecipitation (Co-IP).  Leakproof snap caps may be penetrated by a syringe and will no pop open during autoclaving.  Compatible with many thermal cyclers and able to tolerate centrifuge speeds up to 20,000 RCF.

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.

The ice-free FreezeBox™ is a new type of energy-saving environmentally friendly, safe, additive-free freezer box. The ice core aluminum alloy shell with high thermal conductivity of the alloy module ensures that the samples can be quickly cooled. The temperature difference between the sample holes is less than 0.1°C, which maintains a uniform temperature throughout the samples. Because the FreezeBox™ is ice-free, lightweight, and easy to carry it is ideal for collection of biological samples, or even to preserve unstable nucleic acid samples. Its compact design and ice-free technology allow for convenient use in a tissue culture incubator, bio-safety cabinet or any other application with limited space. The FreezeBox™ can be used with different ice cores, and a variety of thermal test tube modules allowing for usage with different samples and temperatures.

Features:

  • Low temperature protection for biological samples
  • Uniformity of temperature between the holes ensures consistency among samples
  • Different ice cores available for different storage temperatures
  • Applicable to a variety of thermal pipes and modules
  • Lightweight, compact, easy to carry when collecting biological samples
  • Easy to clean and disinfect
  • Highly durable and suitable for frequent and repeated use

Usage:
This product is easy to assemble and simple to use. After storing the ice core in the ultra-low temperature refrigerator for several hours place the desired tube module on the chilled core, and insert your sample or plate into the tube module. If you choose to use dry ice, take the core out, directly fill approximately 200g dry ice, then lay the tube modules on top of it.
