|
 | The relationship between temperature holding capacity of each type of box versus time shows that the standard cardboard box with insulating plastic insert is three times more effective than the uninsulated standard container. Also, the presence of unmelted ice within the shipping container cannot be considered a reliable sign of safe blood temperature. Thus, it would be more practical and safer to measure the temperature of the blood in the ... |
