Benefiting from a flat bottom, Micronic 4.00 mL tubes also provide an ideal solution for transportation or storage of solid biological samples.
Precision manufactured from ultra-pure grade polypropylene, in a certified Class 7 clean room production environment, Micronic 4.00 mL tubes are available in bulk and in automation-compatible Micronic 48-4 Racks. This 48-well format rack features a laser etched 1D rack barcode on one side and ‘Twist-Lock’ to prevent tubes from turning during screw capping or decapping.
