Our Latest microwave system (The MDS-15) is the culmination of over 20 years of refinement. The MDS-15 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 MDS-15 is a versatile microwave 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 Sineo 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: MDS-15 applies high-energy uniform microwave field, it delivers a rapid digestion with a quick 20 minute cool down time. Sineo has incorporated the latest technology of material design while engineering a very safe, durable and easy to use microwave.   The quartz digestion vessel enables the digestion process to be visible;

□   Initiative wireless remote video monitoring system, together with quartz vessels, makes the reaction be seen clearly at a glance. Pictures and videos can be taken during the entire process;

□   500 ml ultra-large digestion vessel meets the special requirements for the digestion of samples of up to 10 grams.

□   The drying rotor aides in the drying process of samples,

□   Sineo’s patented safety bolt design eliminates the need for explosion-proof membranes and other costly consumables.

□    The Aerospace composite fiber outer vessel ensures the highest level of vessel security.

□    The Large 65L stainless steal chamber and dual magnetron structure, is designed for high energy and uniform microwave field.

□    With over 20 years of experience in the industry Sineo is known as an innovation leader with numerous patents.

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 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 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 the strongest anti-explosion sleeve available.  The carbon fiber sleeve is corrosion resistant, and has better high temperature/impact/ and pressure resistance 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.

Our safety bolt design, ensures samples be closed completely and triggers a quantified pressure relief while over pressurized.  The Safety Bolt unit eliminates the need for safety membranes and other consumables, and ensures the digestion vessel be sealed completely under normal working conditions.   The safety bolt will automatically blow out vertically with the cover to release the excess pressure. Under normal operation, the safety bolt requires no replacement. In addition, The safety Bolt is easy to open for venting after the digestion is finished.

We utilize the state of the art pressure measuring technology with piezoelectric crystal, and high-precision temperature measurement with our Pt sensor.  The entire set of digestion vessels is designed to rotate continuously in one direction, unlike most microwaves which constantly change directions to heat the vessels uniformly.  A side benefit to this design is no tangled probes and less stress on the carousel motor.

The MDS-15 features Quartz digestion vessels and wireless video monitoring so digestions can be viewed on a PC, tablet or smart phone.

The MDS-15's industrial-grade chamber is designed for maximum impact resistance, and the multi-layer chemical resistant coating greatly improves the service life of the system. Like all Sineo Microwaves, the pop up cushioning explosion-proof door provides a passive safety protection system, and it will disable the microwave power automatically if an explosion happens. The efficient exhaust system design achieves fast and safe forced air cooling (20 min cooling time from 200℃ to 60℃), improving operational efficiency.
