Sample Tubes

Sample tubes are an instantly recognizable symbol of science for a reason — they’re used across disciplines and have myriad uses. At diaago, we have an array of storage tubes available from our partner Micronic, which has manufactured high-quality, innovative storage solutions for over 30 years. They offer a complete line of sample storage tubes that fit in the 96-well, 48-well, or 24-well standard rack formats.

Screw Cap Test Tubes

Screw cap test tubes are a popular choice due to the security that they provide for your samples. They can be either internally or externally threaded. The externally threaded tubes are available with 2D Data-Matrix coding for long-term storage and traceability. All tubes are manufactured with medical-approved, virgin polypropylene vinyl, and they exhibit ultra-low protein binding compared to competitors’ tubes.  

Cryogenic Tubes 

Cryogenic tubes are sample tubes that can withstand ultra-low temperatures. They are meant to be able to be stored in vapor state liquid nitrogen. Cryo tubes can be used to store cell samples and other biological materials for a prolonged period. You can choose from either internally or externally threaded cryotubes. With a variety of colors available, you’ll be able to instantly identify your specimens.

Options Available for Sample Tubes

You have a number of different options for standard test tubes to choose from:

  • Internally or externally threaded

  • Range of volume: From as low as 0.50 mL to as high as 6.00 mL

  • V-bottom or U-bottom

  • Non-coded or alphanumeric coded

  • Push caps, screw caps, or low profile screw caps

  • Amber tubes (for light-sensitive samples)

Micronic also offers the following additional options for their test tubes:

  • Gamma Irradiation Sterilization: This process ensures a SAL of 10-6, or a one-millionth probability of microbial survival.

  • Ethylene Oxide (EtO) Treatment Sterilization: When you need to ensure that your sample tubes are completely DNA-free, 

  • Snap Tubes: For no extra charge, tubes may be locked into the rack to prevent sample loss from overturned racks. 

  • Pre-Capped: All tubes may be pre-capped upon request. There are 12 different colors to choose from for ease of visual identification.

  • Pre-Racked: All tubes can be pre-racked upon request and come with a laser-etched 1D rack barcode or custom code.
