Aston RTA:
Gold-plated positive pin for maximum conductivity
High quality Pyrex with a PSU tank supplied as spare in order to have the choice of aesthetics and solidity.
The coil is easy to install thanks to the wide passages and the wire holding during the clamping process.
The optimum coil height is guided by the two supports which will receive the jig in the right position.
Adjustable draw on 2 holes or one only, for a tight or more open coil, while remaining on a restricted type to favour the aromas.
An ultra-precise Airflow which guarantees a unique cooling of the coil and a maximum of flavours, not altered.
Filling is done by unscrewing the top cap.

The materials used are:

Stainless steel 304 L for the whole rta.
Stainless steel 304 L for pine with gold plating
Pyrex for the original equipment tube and PSU (Polysulfone) for the second tube
Delrin for the drip tip
Top cap and sandblasted airflow ring for the MATE SS version.
