Ashing, fat determination and extraction on microwave platforms.

PYRO microwave ashing system

Inorganic Sample Preparation · 5 models

Conventional dry ashing is measured in hours, and traditional fat determination adds a separate hydrolysis and solvent extraction sequence. Microwave heating changes the timescale. PYRO combines microwave power with an oxygen-rich airflow; the cavity reaches 1000 °C in eight minutes and holds 1200 °C, and samples ash without a separate charring step. The same direct heating principle drives the ETHOS X platform for fat determination, solvent extraction and solvent-free extraction of essential oils.

8-minute heat-up

Microwave heating takes the PYRO cavity from room temperature to 1000 °C in eight minutes.

1200 °C working limit

A vacuum-formed alumina ceramic cavity holds 1200 °C with effective thermal insulation.

44 samples, 40 minutes

One ETHOS X extracts up to 44 samples in 40 minutes in batch operation.

No solvent for oils

Solvent-free extraction adds no organic solvent or water, and the extract goes straight to GC-MS.

Models

The family covers more than ashing. ETHOS X runs three distinct applications from one platform: total fat in food and feed, batch solvent extraction of up to 44 samples in 40 minutes, and solvent-free microwave extraction that yields a first drop of essential oil in five to eight minutes. MiniLab 3000-i closes the loop by preparing the calibration standards and QC additions that follow, feeding AAS, ICP and ICP-MS runs.

PYRO

Microwave ashing and high-temperature system

PYRO is a microwave ashing system for dry ashing, ash content, ignition residue, fusion and high-temperature synthesis. Microwave heating raises the cavity to 1000 °C in eight minutes and holds 1200 °C, while a Venturi-fed oxygen supply lets samples ash without a charring step. A vacuum-formed alumina ceramic cavity keeps the heat in and the airflow clears smoke continuously.

  • Working temperature up to 1200 °C
  • Room temperature to 1000 °C in 8 minutes
  • Venturi oxygen supply and exhaust; no charring step before ashing
  • Vacuum-formed alumina ceramic cavity with good thermal insulation
  • Honeycomb ceramic spoiler and Venturi tube distribute air through the cavity
  • Multi-level airflow control clears smoke and fumes quickly
  • Also used for fusion and high-temperature synthesis reactions

ETHOS X (fat determination)

Microwave fat determination system for food and feed

The fat-determination configuration measures total fat in food and feed without the separate hydrolysis and extraction steps of the traditional method. Operators weigh the sample, hydrolysis and extraction run together, a dedicated vacuum-drying rotor removes solvent, and a second weighing gives the result automatically. A balance and the ETHOS X are the only instruments required.

  • Total fat in food and feed in one automated workflow
  • Weighing, hydrolysis and extraction in a single step
  • Dedicated vacuum-drying rotor evaporates solvent quickly
  • A second weighing produces the fat result automatically
  • 15 samples per batch, 3 g to 15 g each
  • Whole determination finished within 3 hours
  • Lower reagent consumption than traditional hydrolysis and extraction
Samples per batch15
Sample size3–15 g
Batch timeWithin 3 h

ETHOS X (solvent extraction)

Microwave solvent extraction system

The solvent-extraction configuration applies microwave heating to batch extraction of samples. It combines high efficiency with parallel processing: one system handles up to 44 samples in 40 minutes. The same platform is offered in several configurations, so laboratories can cover different extraction applications with one instrument family.

  • Up to 44 samples in 40 minutes on one system
  • Microwave-assisted solvent extraction in batch format
  • Combines high efficiency with parallel sample processing
  • One platform serves several ETHOS X application configurations
  • Suited to laboratories extracting many samples per day

ETHOS X (solvent-free extraction)

Solvent-free microwave extraction (SFME) system

The SFME configuration extracts essential oils and aroma compounds with no added solvent or water. Microwave heating releases the oil, which distills and is collected; the first drop arrives in five to eight minutes, and a typical extraction finishes in about 40 minutes rather than the hours of steam distillation. Extracts are ready for GC-MS without evaporation or solvent exchange.

  • No organic solvent or water added during extraction
  • First drop of essential oil in 5–8 minutes
  • About 40 minutes replaces hours of steam distillation
  • Extract suitable for GC-MS without evaporation or solvent exchange
  • Shorter exposure and less moisture reduce thermal decomposition and by-products
  • Extraction capacities of 2 L, 5 L and 12 L
  • Industrial model with a 150 L cavity for 75 kg of material

MiniLab 3000-i

Automated liquid handling platform for inorganic analysis

MiniLab 3000-i prepares inorganic liquid samples for elemental analysis: dilutions, calibration curves, mixed standards, internal standard curves and quantitative additions of standards and QC samples. It supplies the standards, curves and prepared samples that AAS, ICP and ICP-MS runs depend on, and takes over the repetitive liquid handling that otherwise consumes analyst time.

  • Automates inorganic liquid sample preparation and dilution
  • Builds calibration curves and mixed standards
  • Prepares internal standard curves
  • Adds standards and QC samples quantitatively
  • Supplies prepared standards and samples to AAS, ICP and ICP-MS
  • Covers other routine liquid handling operations

Questions

Before you buy.

How fast is microwave ashing compared with conventional dry ashing?

PYRO reaches 1000 °C from room temperature in eight minutes and holds a working temperature of 1200 °C. A Venturi oxygen supply lets samples ash without a charring step, and the airflow clears smoke from the cavity. Ashing that takes hours by conventional heating finishes in minutes.

How many samples can one ETHOS X handle?

It depends on the configuration. Fat determination processes 15 samples of 3–15 g within three hours. Solvent extraction handles up to 44 samples in 40 minutes. Solvent-free extraction is available in 2 L, 5 L and 12 L capacities, with a 150 L industrial cavity that holds 75 kg of material.

Does solvent-free microwave extraction need any solvent?

No organic solvent or water is added. The first drop of essential oil appears in five to eight minutes, and a routine extraction takes about 40 minutes against hours for steam distillation. Because no solvent is used, the extract can go to GC-MS without evaporation or solvent exchange.
