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.
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 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.
PR1MA™ - CryoTag Sheets for Vials
Labeling containers like vials can be challenging when dealing with exposure to moisture, varying temperatures, and limited surface space. Because of this, high-quality cryogenic labels are crucial for laboratories to minimize errors, enhance accuracy, and boost cost efficiency.
PR1MA™ Cryogenic Labels feature a premium adhesive designed to stick to already-frozen surfaces, even in wet or cold conditions. This adhesive remains effective at temperatures 80ºC down to -196ºC. Constructed from thermoplastic film and coated with a glove-friendly, cryogenic adhesive, these labels secure strongly to various surfaces.
PR1MA™ - CryoTags can be printed or written on and will not bleed, smear, or crack, eliminating the need for additional lamination. They are perfect for distinguishing various specimens after prolonged periods of cold storage.
These labels come on sheets to be printed on by any laser printer!

Laser Tough-Tag® Sheets for 0.5 and 1.5 mL Tubes
Specially designed to permanently accept laser printing.
Laboratory labels formatted for laser printers. Tough-Tags® are chemically inert laboratory labels that strongly adhere to microtubes, test tubes, storage boxes, and microscope slides. They resist organic solvents and caustic agents. Tough-Tags® are perfect for accurately identifying important samples stored in moderate freezer temperatures (121 to -40°C)
Tough-Tags are pre-cut, peel-off labels that accept any marking instrument and are perfectly sized to fit microcentrifuge tubes and other containers in the laboratory. Tubes with Tough-Tags wrapped around them will still slide easily in and out of rotors without binding because the labels are thin and the adhesive does not migrate from behind the label even after boiling and autoclaving.
- Colors: White, Blue, Green, Orange, Red, Yellow, or "Rainbow Pack"
- Rainbow Pack includes 5 sheets of each color: Blue, Green, Orange, Red, and Yellow
*For best adhesion, it is recommended that siliconized surfaces be avoided.
