Purification apparatus

A purification apparatus that separates a target substance contained in a mixed sample based on a specific gravity difference, the purification apparatus comprising:

• a container that receives the mixed sample;
• and
• a strainer arranged in the container, wherein
• the container includes
• an introduction port to introduce a treatment solution for treatment of the mixed sample into the container, and
• a discharge port to discharge the treatment solution from the container,
• the strainer is configured to catch the target substance in the treatment solution discharged through the discharge port and to hold the target substance in the container,
• the treatment solution further includes
• a decomposition solution that decomposes a contaminant contained in the mixed sample,
• a heavy solution to separate the target substance, and
• a cleaning solution that cleans the mixed sample, and
• the purification apparatus further comprises:
• a first reservoir where the decomposition solution is stored;
• a second reservoir where the heavy solution is stored;
• and
• a third reservoir where the cleaning solution is stored.
