Advanced Vessel Technology

Vent and Reseal

‘Vent-and-reseal’ vessels are the foundation of Milestone’s microwave technology.
Continuously enhanced, this patented (US Patent 5,270,010) technology provides analysts with unsurpassed performance capabilities.

  • Highest temperature and pressure
  • Highest safety standards
  • Easy of use
  • Fast air cooling

The ‘dome-shaped’ spring is temporarily flattened in case of overpressure (1), allowing the cap to lift-up (2) slightly and release the pressure. Once the pressure has been released, the cap closes again (3), and the microwave program can continue.

While other devices use membranes or burst disks which render a vessel useless after venting, the Milestone system releases only the excess pressure from the vessels. Therefore, there is no stress in the case of a vessel’s bursting.
This vessel technology is the perfect complement to the ETHOS One pressure responsive door and of the automatic door locking system, resulting in the safest microwave system available today.

Burst disk venting

When a specific pressure is achieved, the disk bursts, and the pressure dramatically drops to zero. Sample is lost, and the program must be manually stopped.

Milestone unique vent-and-reseal venting

Only the excess pressure is released from the vessel, and the digestion process can be completed in full safety obtaining reliable results.
