The Microwave Digestion System with unique, optical temperature and pressure monitoring of each individual sample during Acid Digestion.

Patented optical procedure to measure the temperature and pressure of each individual sample guarantees active and dependable reaction monitoring. The sample material never comes into contact with sensors or probes. Complicated connection of sensors to sample vessels is totally eliminated.

Reproducible acid digestion processes thanks to homogeneous microwave distribution.
Microwave digestion with active reaction monitoring.
"Swing Top" with electronic lid locking for the highest level of safety and ease of handling.
Stainless steel housing with PFA coating provides effective protection against corrosion.
Vent system prevents emissions and corrosion.
Extremely easy operation and documentation by the control unit or an external PC.
The right pressure vessel for every application

CONTROL SYSTEM

The extremely rapid heating of samples in the microwave field coupled with occasionally induced spontaneous reactions necessitates very rapid reaction monitoring in order for digestion processes to be performed safely. Based on the contact-free sensor technology the microwave power will be controlled by the delay-free determined sample temperature and sample pressure. Only in this way can spontaneous reactions be effectively suppressed and a safe reaction progress be ensured

SAFETY

During microwave pressure digestion, risks generally arise as a result of reactions going "out of control". The innovative sensor, control, and safety concept of the speedwave® four reduces these risks to a minimum, providing the highest possible level of safety in all operating conditions.

Durable, pressure-resistant PFA-coated stainless steel housing;
Swiveling lid with electronic lock;
3 interlock switches to monitor the swing top lid;
3 excess temperature switches to monitor the oven chamber and the electronics;
Temperature and pressure monitoring of all samples in real time;
Shut down in case of critical operating conditions;
Reliable rupture discs to provide protection in case of excess pressure;
Integrated gas collection system to effectively prevent emissions;
Controlled release of residual pressure when the digestion vessels are opened

PRESSURE VESSELS AND OPTIONS

Task-specific pressure vessels or insert systems made of high-quality TFM are available for nearly every application area. They are characterized by their extraordinarily high levels of safety and durability while simultaneously being easy and simple to handle. No need for tools to open or close.

TOUCHSREEN CONTROLLER

A monochrome, 5.7” touch screen (320 x 240 pixels) facilitates a large, clear representation of the data. The system is controlled by a Power PC 5200 (266 MHz, 64 MB RAM) with Linux operating system. The storage capacity for method programs and data records is virtually unlimited. Maximum operating convenience is obtained using the control unit via an external PC. The speedwave® MWS four® is integrated into a network and can be activated and controlled from every computer in the LAN. No special software required and password protected.

Intuitive operation enhances easy handling. Temperature and pressure data of all samples can be represented in real time and documented in compliance with customary quality standards. Pre-installed standard programs meet many requirements such as EPS 3051, EPA 3052 or EPA 3015. Programs can be modified or extended by the user as needed. One program processes the parameters for target temperature, maximum output, maximum pressure, heating up time and holding time in up to 5 program steps.
