1. Unrivaled Safety: Xtra Fiber Technology
Our explosion-proof outer vessels are crafted from composite Xtra Fiber, a material far superior to the industry-standard PEEK.
Extreme Resistance: Withstands pressures up to 10,000 psi and temperatures up to 600°C.
Indestructible Build: It is lighter than metal but harder than steel, providing a passive safety barrier for the operator.
Auto-Pop Door: The industrial-grade chamber features a sliding explosion-proof door that automatically disables microwave power in the event of an overpressure incident.
2. Precision Sensing: Piezoelectric Crystal Technology
Unlike competitors who use long, fragile air-pipes (400-600mm) that are prone to leaking and twisting, the MASTER series uses advanced piezoelectric sensors.
Direct Control: Accurately measures and controls pressure up to 12 MPa with ultra-short (120mm) cables.
Zero Cross-Contamination: The sensing components are completely isolated from the sample.
Uni-Turn Rotation: Enables continuous 360° one-way rotation, ensuring uniform heating without the "back-and-forth" motion that stresses turntable motors.
3. High-Throughput Efficiency (Up to 100 Samples)
Designed for the modern ICP-MS and ICP-OES workflow, the MASTER series can process up to 100 samples simultaneously.
UTH-Caro Design: The carousel frame acts as a microwave stirrer, guaranteeing that every vessel—whether in a 40 or 100-vessel setup—receives identical energy for even digestion.
Rapid Cooling: The high thermal conductivity of Xtra Fiber, combined with a powerful exhaust, drops vessel temperatures from 200°C to 60°C in just 15 minutes.
4. Versatile Rotor Options
The MASTER series accommodates a range of rotors to meet your specific application needs:
| Rotor Type | Capacity | Ideal Application |
|---|---|---|
| High-Pressure Rotor | 16 Vessels | Insoluble samples & high-temp organic digestion. |
| Ultra-High Throughput | 40 / 100 Vessels | Environmental testing (Soil/Wastewater) & Food safety. |

| Ultra-High Pressure | 18 Vessels | Extreme conditions & closed microwave synthesis. |
The Ultra High Throughput Closed Microwave Digestion Extraction Workstation features a MASTER cavity designed to support multiple digestion rotors. This flexibility allows laboratories to configure the system based on different sample volumes, throughput requirements, and application needs.
Available digestion rotors include:
- 16-vessel independent frame-type high-pressure rotor
- 18-vessel carousel integrated ultrahigh-pressure digestion rotor
- 40-vessel and 100-vessel ultrahigh-throughput carousel rotor
- 16-position, 200 mL large-capacity carousel rotor
The system integrates several core technologies, including the Xtra Fiber digestion outer vessel, quantified Safety Bolt design, UTH-Caro high-throughput carousel structure, piezoelectric crystal pressure measurement, and Uni-Turn continuous rotation technology. Together, these technologies support a wide range of digestion applications with high consistency and safety.
As analytical techniques such as mass spectrometry continue to expand, laboratories increasingly require faster and more efficient microwave sample preparation. Many conventional high-throughput microwave digestion systems rely on spring-based structures, which often limit pressure resistance, increase leakage risk, cause uneven heating, and complicate operation.
The MASTER closed microwave digestion system overcomes these limitations through its high-pressure design, uniform microwave field distribution, and advanced safety mechanisms, delivering stable performance for demanding, high-throughput workflows.
1. High-Strength Alloy Carousel
The high-throughput vessels are connected by a high-tensile alloy draw bar capable of withstanding pressures of at least 10,000 kg. Each digestion vessel is firmly supported at both the top and bottom of the frame, preventing deformation or leakage under operating conditions of up to 4 MPa and 250 °C.
Comparable systems from other manufacturers typically support maximum temperatures of only 210 °C, limiting digestion efficiency for challenging samples.
2. UTH-Caro Design for Uniform Digestion
The UTH-Caro carousel design rotates and stirs the digestion vessels within the microwave cavity. This movement balances the microwave field and ensures even energy distribution.
As a result, up to 100 digestion vessels can be heated uniformly, improving digestion consistency and reducing variability between samples.
3. Quantified Safety Bolt Design
The Safety Bolt design ensures complete vessel sealing under normal conditions and provides controlled pressure relief if overpressure occurs. Unlike disposable safety membranes, the Safety Bolt securely seals the vessel, preventing loss of volatile elements and supporting complete digestion.
When internal pressure exceeds safe limits, the Safety Bolt releases pressure vertically in a controlled manner. Under normal use, it does not require frequent replacement and allows easy pressure release by opening the vessel cover after digestion.
In contrast, many competing systems use non-metal covers that deform over time, lose sealing capability, and reduce sample recovery due to evaporation or drying.
4. Uni-Turn Continuous Rotation Technology
All digestion vessels rotate continuously in a single direction rather than reversing direction. This design eliminates uneven heating caused by back-and-forth rotation and reduces mechanical stress on the turntable motor.
Short temperature and pressure cables remain untwisted during operation and can be easily removed for maintenance, improving long-term reliability.
5. Rapid Cooling Performance
The Xtra Fiber composite outer vessel offers high thermal conductivity. Combined with an efficient exhaust system, the temperature can decrease from 200 °C to 60 °C within approximately 15 minutes.
This fast cooling significantly shortens total processing time and increases laboratory throughput.
6. Operator-Friendly Design and Tools
A range of ergonomic tools simplifies operation and reduces operator workload. A flexible trolley allows safe placement and removal of a fully loaded high-throughput carousel weighing 15–20 kg, minimizing exposure to high temperature, high pressure, and acid mist.
An electric torque-controlled tool enables fast and consistent tightening of digestion vessels, improving operational efficiency while maintaining safety and repeatability.
