- Built-in exhaust and optional acid scrubber for safer laboratory operation.
- Reliable temperature monitoring with thermocouple or contactless IR control depending on configuration.
Interchangeable Configurations
High Throughput
Designed for routine ashing workflows with capacity for up to 24 quartz fiber crucibles, induced airflow, thermocouple control and dramatic reduction in ashing time.
Sulfated Ashing
Allows direct placement of acid-treated samples into the system without preliminary charring, while acid vapors are exhausted, condensed and neutralized through a dedicated scrubber module.
UltraFAST Heating
Best suited for rush samples and high-temperature applications, reaching 800°C in 5 minutes and supporting processes up to 1200°C with contactless infrared temperature control.
