We use our thermomixer multiple times a week for prolonged periods to digest tissue and isolate mouse DNA in order to validate and verify animal genotypes. This product has preformed consistently with little optimization required. In addition to DNA isolation, the thermomixer has proved to be useful a dry bath for a number of different protocols.

Results Summary

This product is extremely easy to use. The instructions are clear and simple. We have never had any particular issues with this thermomixer functionality but after a year of continuous use (just after our warranty expired) our mixer started making extra noise when running and needed to be serviced. Although it worked efficiently and without altering any sample data before it was sent for servicing.

Features Summary

This system has a very fast heat up feature.
