Safely Store and trace samples

With Micronic's 0.75ml tubes

The 0.75ml cryotubes from Micronic let you store valuable samples in a safe and traceable way. The 0.75ml sample storage tubes are available in either push cap or screw cap format, and can be purchased with one of three codings: non-coded, alphanumeric codes, and 2D Data-Matrix codes.

The Alphanumeric and 2D codes are laser etched into the Polypropylene code area (tube bottom), guaranteeing the highest resistance to solvent attack and ensuring a reliable code reading. The tubes are standard available in the 96-well format Micronic 96-2 Rack, and optionally available in bulk.

Product features

Optimal sealing

Micronic’s internally threaded tubes provide the most optimal seal for sample storage at ultra-low temperatures.


The tubes are available non-coded or with a unique 2D Data-Matrix code on the tube bottom. All racks are laser-etched with 1D barcodes.

Unique molding technique

The black code surface cannot be separated from the transparent tube due to the patented 2K injection molding technique.


Resistant against chemical solvents. The tubes are produced in a class 7 clean room and are RNase/DNase and Pyrogen free.
