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.

Multi-Purpose Test Tubes 12 x 75 mm 
 
Precision-molded from premium-grade plastics and ideal for routine laboratory analysis and procedures. We have applied the lessons learned from over 27 years of manufacturing experience to produce tubes that perform at their highest level. Our tubes are rigorously inspected by our Quality Assurance Department to ensure they surpass our exacting specifications. These tubes are ideal for a wide range of laboratory applications. They are available in several sizes, and from three materials, to meet a variety of needs.

  • - All of the tubes are plastic (polystyrene, polypropylene or polypropylene-copolymer), thus preventing the problem of broken glass.
  • - Polypropylene is chemically resistant, autoclavable and virtually unbreakable.
  • - Polystyrene is clear like glass.


Note that caps are ordered separately. These tubes are not available sterile.
