The Ultra-Low Temperature (ULT) racks from Micronic are based on the globally recognized ANSI/SLAS standards for storage racks, featuring a laser-etched 1D rack barcode on one side of the rack and a ‘twist-lock’ design to prevent tubes from turning during screw cap (de)capping. These racks are compatible with the leading sample storage automation systems.
