Aarke Carbonator Pro
Silicone is only a gasket/seal — what touches your water is Soda-Lime Glass and Metal (unspecified) and Stainless Steel (grade unspecified).
The glass-bottle carbonator with the best water path - glass bottle, steel nozzle, silicone seals; the machine's enclosed steel chamber is what makes glass safe under pressure.
The verdict: Silicone only
The Pro is the rare soda maker where the water path avoids plastic entirely when used with its glass bottle: carbonation happens in glass, the nozzle is stainless steel, and Aarke lists the Pro's materials as SUS304 stainless, glass, and silicone - so the non-glass/steel contact points are silicone seals. The lever-lowered stainless enclosure is what allows glass under carbonation pressure (Aarke's own Carbonator 3 is PET-only for exactly this reason). An optional PET bottle exists but is not needed. Glass type (soda-lime vs borosilicate) is not specified.

What it's made of
| Part | Material | Water contact |
|---|---|---|
| glass bottle dishwasher-safe; Aarke does not specify soda-lime vs borosilicate | Soda-Lime Glass | Yes primary |
| bottle cap brand describes a metal cap; not confirmed as stainless, exact alloy unspecified | Metal unspecified | Yes primary |
| carbonation nozzle stainless spray nozzle - dips into the bottle during carbonation; grade unspecified | Stainless Steel grade unspecified | Yes primary |
| seals / gaskets silicone is the third material Aarke lists for the Pro; sealing points during carbonation | Silicone | Yes seal |
| machine body / protective chamber SUS304; the enclosed chamber is the safety requirement for carbonating in glass | Stainless Steel 304 / 18-8 | No |
| PET water bottle (optional accessory) optional - the machine is fully usable with only the glass bottle | Plastic other / unspecified | Yes primary |
Aarke's flagship carbonator, in the brand's signature all-steel look. A lever lowers a stainless enclosure over the glass bottle, then you carbonate, store, and pour from that same dishwasher-safe bottle. Manual (no electricity), using standard 60L screw-in CO2 cylinders. The glass bottle is heavier than PET and needs more care.
Pros
- Glass-bottle carbonation with a stainless steel nozzle - best water path in the category
- Serve and store in the same glass bottle; dishwasher-safe
- No electricity; standard 60L CO2 cylinders
- Buy-it-for-life build (steel body, metal internals)
Cons
- Expensive - roughly twice the price of PET-bottle machines
- Glass bottle is exclusive to the Pro (spares only from Aarke)
- Glass type (soda-lime vs borosilicate) unspecified by Aarke
