Dielectric Barrier Discharge Experiment Device Reaction Kettle
Product Detail
The DBD reaction kettles (DBD-100A, DBD-100B, and DBD-150A) are sealed enclosures that turn an open dielectric barrier discharge reactor into a closed reaction vessel — letting you run gas-phase, gas–solid, gas–liquid, and liquid-treatment plasma chemistry under controlled atmosphere or vacuum. Each kettle mounts onto a matching DBD reactor and is built for a specific interface and reaction phase, so you can pick the geometry that fits your experiment.
What a reaction kettle adds
On its own, a DBD reactor such as the DBD-50 generates cold plasma between two dielectric plates in open air. A reaction kettle encloses that discharge zone in a sealed chamber with gas and liquid ports, so the working gas, the pressure, and the sample environment are fully controlled. That makes it possible to:
- Control the atmosphere — run reactions under a chosen working gas (air, oxygen, nitrogen, argon, or a mixture) instead of ambient air.
- Work under vacuum or atmospheric pressure — the DBD-100A and DBD-100B operate across both regimes.
- Match the reaction phase — horizontal, vertical, and liquid-handling geometries suit gas–solid, gas–liquid, and liquid-treatment chemistry respectively.
- Keep samples and products contained — useful for powders, volatiles, and liquid media that cannot be processed in an open cell.
Compare the three reaction kettles
All three kettles seal the discharge zone of a DBD reactor; they differ in interface geometry, the reaction phase they are built for, and the reactor they mount on.
| Model | Reaction phase | Interface / orientation | Operating pressure | Compatible reactor |
|---|---|---|---|---|
| DBD-100A | Gas phase, gas–solid | Horizontal | Vacuum & atmospheric | DBD-50 |
| DBD-100B | Gas phase, gas–liquid | Vertical | Vacuum & atmospheric | DBD-50 |
| DBD-150A | Liquid treatment | Sealed kettle | — | DBD-150 |
- Reaction kettles are passive accessories and must be used with their matching DBD reactor device; they do not generate plasma on their own.
- Operating-pressure and detailed dimensional data for the DBD-150A are available on request — browse the DBD reactor line or contact us with your application.
Choosing the right kettle
The difference between the kettles is the interface geometry and the reaction phase each is built for:
- DBD-100A — horizontal interface. Best for gas-phase and gas–solid reactions where the sample sits in the discharge plane, such as surface treatment or plasma processing of powders and flat substrates under a controlled gas. Operates under vacuum or atmospheric pressure on the DBD-50 reactor.
- DBD-100B — vertical interface. Best for gas-phase and gas–liquid reactions where a liquid or suspended medium is involved and a vertical geometry keeps it in place. Also runs under vacuum or atmospheric pressure on the DBD-50 reactor.
- DBD-150A — liquid-treatment kettle. Built for liquid-phase plasma treatment and mounts on the larger DBD-150 reactor, for applications such as plasma-activated liquids and solution-phase chemistry.
Compatibility & what's included
Reaction kettles are passive accessories: each must be paired with the matching DBD reactor, and the reactor in turn with a CTP-series plasma power supply that drives the discharge.
- DBD-100A and DBD-100B mount on the DBD-50 dielectric barrier discharge reactor.
- DBD-150A mounts on the DBD-150 reactor.
- The reactor is driven by a CTP-2000K-series plasma power supply (sold separately).
A reaction kettle cannot generate plasma on its own. The DBD-100A and DBD-100B require a DBD-50 reactor; the DBD-150A requires a DBD-150 reactor. Each reactor is driven by a separately purchased CTP-series supply (CTP-2000K, /P, /A, KM, or KL).
Frequently asked questions
What does a reaction kettle do?
It encloses the discharge zone of a DBD reactor in a sealed chamber so reactions run under a controlled working gas and pressure (vacuum or atmospheric) instead of open air, and so samples, volatiles, or liquids stay contained.
What is the difference between the DBD-100A and DBD-100B?
The DBD-100A has a horizontal interface for gas-phase and gas–solid reactions; the DBD-100B has a vertical interface for gas-phase and gas–liquid reactions. Both run under vacuum or atmospheric pressure and mount on the DBD-50 reactor.
Which reactor do I need?
The DBD-100A and DBD-100B require a DBD-50 reactor; the DBD-150A requires a DBD-150 reactor. A kettle must be used with its matching DBD reactor device.
Can a kettle run on its own?
No. A reaction kettle is a passive enclosure. It needs a DBD reactor to generate the plasma, and the reactor in turn needs a CTP-series plasma power supply (sold separately).
Can it operate under vacuum?
Yes. The DBD-100A and DBD-100B operate under both vacuum and atmospheric pressure, which lets you choose the working gas and pressure for your reaction.
What reactions are these used for?
Gas-phase, gas–solid, gas–liquid, and liquid-treatment plasma chemistry — for example surface activation, plasma-assisted synthesis and coating, and plasma-activated liquids, depending on the kettle.
