Yes - the Pura UVC Bottle is made from stainless steel and is double-insulated, meaning that it can keep hot drinks and soups nice and toasty, and keep water and soft drinks nice and cool. It keeps your drink hot or cold for 24 hours - perfect if you are camping and in the midst of nowhere! You can use if for any hot or cold drinks.  UVC light treatment is not recommended for dairy products as it may affect the taste you are used too, so we would advise not to use it for milk-based drinks.
