Advanced Microwave Hardware

Fast vessel heating
The START E is equipped with an industrial magnetron that provides higher microwave power and allows rapid heating of high-throughput rotors.

Homogeneous microwave distribution
A microwave diffuser located above the microwave cavity evenly distributes microwaves throughout the cavity, preventing localized hot and cold spots.

All stainless-steel construction
The chassis of the START E is made of corrosion-resistant stainless steel, not molded plastic. The cavity and the door are plasma-coated with PTFE to protect the unit. Milestone’s warranty covers the cavity coating against corrosion for 5 years!

Convenient, user-centric design
The START E door includes a shock resistant double-glass window, for easy viewing of the pressure vessels. The door opens downward and it can be used by the chemist as working platform to facilitate the loading of vessels into the microwave cavity.

Fast air cooling of vessels for higher throughput
The START E is equipped with a heavy duty air flow system, placed above the microwave cavity. The air flow rapidly cools the external surfaces of the vessels. An acid-resistant flexible hose connects the exhaust fan to a fume hood, ensuring a safe working environment.
Alternatively, the Milestone vessels can be cooled in a water bath, further reducing the cooling time to less than 10 minutes.

Magnetic stirring in all vessels
The START E can be equipped with a powerful magnetic stirrer with variable speed, allowing the simultaneous stirring of the solutions in all vessels.
Efficient stirring guarantees that the sample continuously remains in contact with fresh solvent and further enhances the microwave extraction process.
