Life Technologies is committed to environmental responsibility and customer satisfaction.  In response to feedback from many of our customers, we are reducing our environmental impact in as many ways as possible, including efforts to reduce the amount of packaging we use in our shipments. In the past, we maintained the quality of  perishable products shipped on Fridays by using larger Styrofoam containers and extra coolant.  Now we ship these products on Monday rather than Friday, which allows us to use less packaging and reduce our impact on the environment, while still meeting the most commonly requested delivery date of Tuesday.
