Medical Waste Sterilizer


The Mark-Costello Co. has been building high pressure steam autoclave
type waste sterilizers for 42 years. Safe and economical treatment and
disposal of biohazardous waste is becoming an issue, not only in the United
States, but around the world. Along with medical facilities, our current long
list of customers, both here and abroad, include International Airports and

Regional Medical Waste Processing Centers.

Systems and Applications

The Mark-Costello Co. Sterilizers use the basic principle of high temperature
steam under pressure in an enclosed fully automatic steam retort. The
sterilizer comes completely assembled and ready for simple final
connections. All chamber vessels are built in accordance with requirements
of the ASME Pressure Vessel Code. All Mark-Costello Co Sterilizers are
equipped with multiple safety features necessary when operating pressure
vessels. The entire control panel for the standard sterilizer is Underwriters’
Laboratories listed and labeled.

  • A sterilizer consists of a steel chamber sealed by a charging door. Steam is introduced into the inside chamber which is designed to withstand elevated pressures. Because air is an effective insulator, the removal of air from the chamber is essential to ensure penetration of heat into the waste. This is done by gravity displacement or vacuum.
  • A steam sterilizer is designed to use steam under pressure as the sterilizing agent. Steam or moist heat is the most effective and practical sterilizing agent in general use today. Bacteria and their spores are destroyed within minutes when exposed to direct contact with moist heat under pressure.
