Microwave Digestion System

Torontech TTMWDXV is a high-throughput, multi-functional closed microwave sample preparation workstation with the latest technology and a lifetime warranty on the core component.

Versatility: The TTMWDXV is a versatile workstation which can handle the routine work, and more complicated and demanding samples in your prep rack with a wide variety of vessels to choose from.

Safety is priority number one! At Torontech we put safety at the top priority, which is why we have painstakingly designed every aspect of our microwave system with the highest level of security measures, such as the use of aerospace composite fiber vessel sleeves, and our patented Safety Bolt.

Efficient by design: TTMWDXV applies high-energy uniform microwave field, it delivers a rapid digestion with a quick 20 minute cool down time. Torontech has incorporated the latest technology of material design while engineering a very safe, durable and easy to use microwave.

Features

  • The outer vessel of TTMWDXV exclusively made by ultra strength aerospace composite fiber is invincible in anti-explosion, and its performance indicators such as corrosion resistance, high temperature/impact/pressure resistance are far better than that of the widely used modified PEEK engineering plastics vessel (this material is fusible at high temperature, fragile at high pressure and explosive by chemical corrosion), fundamentally eliminating safety risks to operator in use
  • Quantified safety bolt design, ensures samples be closed completely and triggers a quantified pressure relief while over pressure; Safety Bolt unit, instead of safety membrane and other consumables, ensures the digestion vessel be sealed completely under normal working conditions, which avoids the loss of volatile elements and incomplete digestion. And only when the pressure is too high and may constitute a danger to the safety, the safety bolt will automatically blow out vertically and the cover auto-up to release the pressure, achieving quantified vertical blast pressure-relief to guarantee its well operation. Under normal operation, the safety bolt requires no replacement. In addition, it is easy for venting to open the cover after completion of digestion.
  • The industrial-leading pressure measuring technology by piezoelectric crystal and high-precision Pt sensor temperature measurement, through closed-loop control of microwave power by inverter technique, ensure the accuracy of pressure and temperature monitoring and control. The application of patented piezoelectric crystal brings complete isolation of samples from pressure measurement system in digestion process, thoroughly solving the problems of cross contamination of samples due to commonly used air pipe in market and of the limitation in digestion samples because of low-pressure proof of air pipe.
  • The whole set of digestion vessels was designed to rotate continuously in one direction, it breaks conventions of <360 ° back and forth rotation, avoiding uneven heating on vessels and reducing impact on turntable motor to extend service life. The temperature and pressure cables are short, that they are free from twisting in running and can be disassembled easily.
  • The new industrial design is smart and colorful, that in line with the needs of modern laboratory construction needs. It re-layout its internal structure more scientifically, with the 65L industrial 316L stainless steel reactor chamber and dual magnetron structure, ensures uniform heating of the microwave and high microwave power emitting low-pressure proof of air pipe.

  • Innovative remote wireless video monitoring system, together with the high-intensity transparent quartz vessel, makes the digestion process clearly visible. Mobile phones and tablets can realize the observation and monitoring of the reaction, making the operation safer and more convenient.
  • Sturdy and durable industrial-grade chamber design strengthen its impact resistance, and multi-layer chemical resistant coating greatly improves the service life and safety of the system; the popup cushioning explosion-proof sliding chamber door (Auto-Pop structure) builds a passive safety protection system, and it can disable the microwave power automatically once explosion happens; efficient exhaust system design achieves fast and safe forced air cooling (20 min cooling time from 200°C to 60°C), improving operational efficiency.

Conventional digestion

With 16 high-throughput RV100 digestion vessel set, TTMWDXV can work for long time digestion at ultra high temperature. It meets the requirements for most of the digestion tasks; the new 8 QZ-100 quartz closed vessel set dramatically improves the digestion capability and visibility, even the most demanding materials could be successfully digested. With remote Wi-Fi video monitoring system for quartz vessel, the whole process can be observed, pictures and videos are available during the entire process.

16 RV100 ultra-high-strength frame closed vessel

16 RV100 ultra-high-strength frame closed vessel 16 high-throughput RV100 digestion vessel set adopts the latest technologies and high-end materials, it is capable of long time digestion work under high temperature and pressure, which can meet the needs of vast majority of digestion tasks. It is especially suitable for the test house or labs handling with various sample types and large capacity. RV100 is also suitable for the applications of solvent extraction, microwave kjeldahl nitrogen determination and microwave hydro-thermal synthesis, etc.

 

TTMWDXV-DR microwave sample drying rotor

TTMWDXV-DR microwave drying rotor realizes rapid and uniform drying, it takes the moisture off sample through microwave heating and vortex air. The sample drying time is only a quarter of that required by conventional heating. The special design of the air inlet and outlet can prevent sample from contamination and loss, at the same time, there is no carbonized risks of the sample by microwave heating. The heating task can be completed without any modification of the main machine. It meets the standard for special sample testing like soil.
