Functional vessels for your various application needs


□ Conventional digestion:

With 16 high-throughput GP-100 digestion vessel set, MDS-15can 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 improvesthe 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 canbe observed, pictures and videos are available duringthe entire process.


□ Ultra-high sample amounts digestion:

LV-500 digestion vessel carousel enables eight 500ml ultra large vessels to digest simultaneously, upgrading the sample amount to an unparalleled level of 10 gram. With magnetic stirring feature, sample digestion could be done more quickly and thoroughly. Innovative Safety Bolt design ensures the combination of vertical & quantitative pressure relief and complete digestion. The digestion tasks of high sample amount thus could be accomplished. 


□ Sample drying:

The F-DRY drying rotor supports rapid and uniform microwave drying, the sample drying time is only a quarter that of traditional method, it can also prevent sample contamination and carbonation. There’s no need of any modification to the main machine to complete the drying task.

□ Microwave extraction, microwave Kjeldahl Nitrogen Determination, etc:

Sineo’s application engineers have developed the application methods for microwave extraction, microwave Kjeldahl nitrogen determination, etc. Our technical support is at your service all the time.

The outer vessel of MDS-15 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, ensuressamples be closed completely and triggers a quantified pressure relief whileover pressure; Safety Bolt unit, instead of safety membrane and other consumables,ensure 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 thesafety, the safety bolt will automatically blow out vertically and the coverauto-up to release the pressure, achieving quantified vertical blast pressure-relief to guarantee its well operation. Under normal operation, thesafety bolt requires no replacement. In addition, it is easy for venting toopen 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 andcontrol. 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 andpressure cables are short, that they are free from twisting in running and canbe disassembled easily. 


The new industrial design is smart andcolorful, 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 steal reactor chamber and dual magnetron structure, ensures uniform heating of the microwave and high microwave power emitting.


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 pop up cushioning explosion-proof sliding chamber door (Auto-Pop structure) builds apassive safety protection system, and it can disable the microwave power automatically once explosion happens; efficient exhaust system design achieves fast and safe forcedair cooling (20 min cooling time from 200℃to 60℃), improving operational efficiency.
