Duo’s borosilicate glass carafe has an extremely low coefficient of thermal expansion, making it resistant to thermal shock. In other words, you never have to worry about Duo cracking due to cold or hot temperatures. NOTE: This carafe is only compatible with the 2nd generation Duo (sold after October 2015). It does not come with grey silicone bootie.
Check the Duo generation
This replacement glass is listed for the second-generation Duo, sold after October 2015. The grey silicone bootie is not included, so check the brewer generation and the separate base piece before ordering.
