Supercritical Fluid Extraction Facilities

General Description

Supercritical fluid extraction (SFE) facilities employ supercritical gases to extract an active component from a natural substance. They are also used in the sterilization of medical materials, the removal of impurities, and in the cleaning of electronic and functional materials. MKK has a well-established track record in the manufacture and supply of SFE systems that range from small screening units to full-feature systems , ranging from 100 ml to 600 L in extraction vessel capacity, and has accumulated a wealth of technical data and information on SFE technology in general.

  1. MKK uses its wealth of experience in the engineering of each vessel , equipment and accessories employed for the systems, best suited to a particular process.
  2. MKK manufactures extraction and separator vessels in conformity with Japanese regulations and standards, thus facilitating maintenance and the acquisition of regulatory approvals. Should other regulation and standard is required, it is also applicable upon consultation.
  3. MKK extraction and collection vessels use “Malok” self-tightening lids originally developed by the company itself which facilitate the opening and closing of the lids even in large-scale SFE systems.
  4. MKK SFE systems are designed and manufactured incorporating raw material handling, cleaning, automation and other peripheral technology to deliver the highest levels of reliability.
