Milestone microwave extraction systems - Start E

The StartE can simultaneously process multiple samples in a matter of minutes. Microwave assisted extraction uses closed vessels to heat the extraction solvent above its atmospheric boiling point. The elevated temperature increases the solubility of the analyte of interest and lowers the viscosity of the solvent, allowing it to better penetrate the matrix. Higher temperatures help overcome matrix effects and accelerate the desorption and diffusion of the analyte molecules. This all leads to dramatically reduced extraction times. The Ethos 1 system can also be used for microwave extraction

  • Microwave extractions completed within minutes - a fraction of the time of traditional methods
  • Higher analyte recovery than traditional methods
  • Easily adaptable to existing extraction chemistry with use of both polar and non-polar solvents
  • Reproducible extractions ensured through precise software based control
  • Reduced costs due to lower solvent usage and disposal
  • Faster air cooling of samples for higher throughput
  • Homogeneous microwave distribution throughout the cavity preventing localised hot and cold spots

The new EasyCONTROL software is the most advanced and powerful operating system in the field of microwave sample preparation.Automatic, real-time monitoring and feedback-based control of multiple parameters offers unsurpassed process control. Simply recall a factory stored program or create a new one. Press 'Start', and the system will automatically follow the defined temperature or pressure profile, utilising a sophisticated PID algorithm

Actual temperature profile

  • Microwave power is automatically adjusted based on continuous feedback allowing the reaction to follow the desired temperature profile

Advanced Reaction Sensors
The START E is equipped with the most advanced reaction sensors, including contact-less temperature and pressure control in all vessels, and direct temperature and pressure control in a single reference vessel

Direct temperature control
The ATC-FO Fibre-Optic Automatic Temperature Control system allows for direct continuous monitoring and control of a reference vessel. The temperature sensor is housed in a thermowell and protected from chemical attack by a multiple layer of inert PTFE and ceramic, ensuring trouble-free operation

Direct pressure control
The APC Automatic Pressure Control system allows for direct monitoring and control of a reference vessel. Pressure monitoring and control is ideal to maintain pressure limits within the vessel's specifications

Contact-less temperature control in all vessels
The START E features a focused, high sensitivity infrared sensor for contact-less temperature monitor and control of all vessels, with individual temperature profiles for each vessel

Contact-less pressure control in all vessels
Unlike contact-less temperature control devices, that focus on one vessel at a time, this sensor monitors vapour concentration in the entire microware chamber, and effectively controls all vessels simultaneously, preventing any leakage of organic solvents
