I can easily achieve -78°C bath by mixing dry ice pellets and isopropanol (99%). Some literature I found says you can reach -100°C with Diethyl ether and dry ice but my mixtures (CO2 & Diethyl ether) so far only reach -78°C. anyone have some info on ratio of the mixture. How else to get -100°C (without resorting to LN2 mixtures)? Thanks
