Microwave Digestion System

OVERVIEW

W1900 Continuous Emission Microwave Digestion System The unique design of the W1900 allows the operator complete control of power and time. Our technology integrates the functional operation and oven components into one single unit. The continuous microwave emission enables consistent digestion for a set period of time with constant power, as well as real time temperature monitoring. Its features include interlocking door safety, fume exhaust and a PTFE coated cavity. Water, soil, food, pharmaceutical, metal, oil and many other samples can be easily digested.

Varsal Advantages:

  • Continuous 1000W microwave emission system
  • Real time temperature monitoring
  • Integrated operating system and oven in one single unit
  • Microwave leakage of < 1mV
  • Maximum cooling time of 15 minutes
  • Intelligent programming with pre-installed EPA methods
