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.

MIDSCI™ Cryogenic Labels - Sheets

Labeling frozen vials, microtubes, microplates, glass tubes, freezer boxes, plastic bags, and other containers can be a challenge when stored in temperatures below -20ºC.
Providing a high-quality Cryo label is essential for laboratories, researchers, etc. It will provide fewer errors, better accuracy, and more proficiency and all of this leads to better results at a better budget.  

We offer a high-quality adhesive that can stick to already-frozen vials and other objects. The adhesive on this type of label will adhere to a surface in wet and/or cold conditions. The adhesive on the label is specifically designed to stick in temperatures below -80ºC and as low as -196ºC. When storing in deep freeze liquid nitrogen or vapor phase liquid nitrogen our Cryo labels will stay in place. MIDSCI™’s Cryo labels are resistant to smearing without any additional lamination. They also won't become brittle or cracked.

 

Our cryogenic labels are made of thermoplastic film and coated with a glove-friendly cryogenic adhesive. This special adhesive allows the label to remain strong and sticky so that it can be securely attached to stainless steel, aluminum, paint, powder-coated metal, and iron.

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.
