Chemical desalter packets made by the Van Brode Milling Company were designed to be used in conjunction with the desalinization bags. The desalter kits in the survival rucksack contained a desalter process bag, desalter tablets, and bag repair tape. The desalter bags are plastic with a filter at the bottom. Approximately one pint of seawater is put into a bag and one tablet added. After one hour, drinking water may be taken through a valve on the bottom of the bag.
This bag was not flown. NASA transferred it to the Smithsonian in 1978.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
