We utilize the Timestrip® Plus indicator to ensure that our goods arrive at the end-user in good condition and that the cold chain has not been broken for any significant time period. When we get calls from customers letting us know that the Timestrip® has been activated, we replace the reagents immediately. The benefit is, that this is a service only Siemens gives to their customers in South Africa and that we are sure our products are arriving without having been exposed to high temperatures, which may compromise results in certain circumstances.
