The 6.00ml Micronic storage tube in 24-well format has a large working volume of 4.80ml (working volume at +21ºC). These tubes are available Non-coded or with an unique 2D Data Matrix code. The 6.00ml Non-coded tubes provide a cost-effective solution for low temperature storage without compromising sample quality and safety. The tubes with a 2D Data-Matrix code permanently laser-etched on the bottom identify the sample, its coordinates within a 24-tube storage rack, the particular rack and the location of the rack in your freezer. For highly accurate and reliable results – Micronic 6.00ml tubes are produced from medical-grade polypropylene. To ensure high sample integrity, even down to ultra-low temperatures, Micronic also offers a ‘single turn’ screw cap that stays securely in place even during repeated freeze-thaw cycles.
