No dry ice is necessary
We offer an external thermostat, which goes down to approximately -60 °C and a double insulated, stainless steel cooling vessel, that supplies all the cold- and gas traps.
It has removable and supplementary insulated tops to prevent thermal losses. With this accessory installed, no dry ice is necessary.
