The Multiwave 7000 integrates the famous concept of Anton Paar’s HPA-S with the latest, well-developed microwave technology, constituting a new level of microwave digestion. The innovative pressurized digestion cavity (PDC) enables achieving temperatures of up to 300 °C and pressures of up to 199 bar.
This guarantees thorough digestions of all samples types like food, polymer, environmental, cosmetic, geological, pharmaceutical, petrochemical and chemical samples. Excellent features help save valuable time and decrease running costs. The Multiwave 7000 comes with affordable vials of various sizes with plug-on caps and racks of up to 28 positions. Combined water cooling reduces the cooling times and increases the sample throughput.
- Small-sized design with a combined cooling system
- Digestion of various samples can be performed in one run with the same method
- Minimal running costs
- Pressure-sealed glass, quartz or PTFE-TFM vials are available
- Comes with ready-to-use methods and tailored application support
Key Features
Complete Digestions of all Sample Types
All sample types like food, environmental, cosmetic, polymer, pharmaceutical, chemical, geological and petrochemical samples can be digested with the help of Multiwave 7000, even in the same run by making use of the same method.
The Multiwave 7000 can be utilized with high (≥0.5 g) and low sample amounts (≤0.1 g) as well as high (≥50 mL) and low sample volumes (≤100 µL). Pressure-sealed glass, quartz or PTFE-TFM vials as well as sealed quartz vessels (example for osmium determination) allow the use of all common digestion acids. Moreover, sample stirring can be executed to assist the digestion of floating samples.

Streamlined Workflow
The Pressurized Digestion Cavity (PDC) revolutionizes the sample preparation workflow of the users:
- It is easy to place vials on an analytical balance, and, therefore, there is no need for weighing boats
- Sample weights are transferred directly to Multiwave 7000
- The filled PTFE-TFM rack is securely transported in a closed PTFE liner (<1 kg)
- The vials are covered with the help of plug-on caps, thus avoiding the need for tools or screwing
- Ready-to-go methods and tailored application support eliminate the need for laborious method development
- Automated pressurization as well as pressure discharge and exhaust available if acid fumes are detected
- Simple cleaning and storage as a result of the use of disposable vials and strong vial components, as well as automated cleaning procedures in Multiwave 7000
- Software-guided automated opening and closing procedures are the norm

Low Running Costs and the Highest Number of Vessels
The Multiwave 7000 incurs low running costs and offers the highest number of vessels in the cavity because of affordable thin-walled quartz, disposable, and PTFE-TFM vials, which are closed with strong and re-usable plug-on caps. It is possible to upgrade the Multiwave 7000 for various sample weights and volumes with inexpensive PTFE-TFM racks.
The temperature sensor, which is generally a crucial handling part, is fitted in the PDC, leading to an instrument that is easy to maintain. This implies that the temperature sensor is completely shielded by the PTFE-TFM liner.

Compact Design with Integrated Cooling System
Fulfilling the needs of versatility, high pressure and high temperature often end up in instruments with a huge footprint. Yet, this is not the case with the Multiwave 7000. As a result of the built-in touchscreen, combined water cooling and a Pt-100 temperature sensor within the PDC, exclusive compactness is realized.

Full Communication and Outstanding Safety
The Multiwave 7000 transmits automated notifications of completed runs and events through email and provides a visual notification and audio notification through SMART LIGHT. Moreover, the Multiwave 7000 can be remotely regulated through VNC from the user’s computer, mobile phone or notebook, which enables users to follow the experiment from any place.

Applications |
All kinds of samples can be digested with all racks. Choose your rack according to whether you want to run with pressure-sealed vials or sealed quartz vessels and according to the required sample amount, sample volume, or reaction mixture. |
* Depending on the sample amount the filling volume varies. There is no minimum filling volume.
