The distillation apparatus adopts a high borosilicate glass integrated design, including a 250 mL round bottom flask, a straight condenser tube, a connecting tube, and a thermometer sleeve, with a standard interface of 19/26 and good sealing. Equipped with a lifting iron platform and universal clamp, assembly only takes 2 minutes, suitable for classroom demonstrations of ethanol water separation or seawater desalination experiments. The side end of the condenser tube can be connected to a micro water pump or tap water, with adjustable flow rate; The bottom conical collection bottle has a scale, making the recovery rate clear at a glance. The device is safe and easy to operate, making it an essential micro distillation kit for chemistry.
