The CSM-eSTEP was designed as a simple and cost effective E-cigarette puffing machine. Because of it's small size and SIGNIFICANTLY lower cost (when compared to traditional smoking/vaping machines), the eSTEP is ideally suited for small scale analytical or inhalation exposure applications as well as pilot studies.

The device consists of a micro-controller driven control box and a modular holding chamber which can accommodate disposable, or cigalike, types as well as tank types (either button or flow activated). The modular E-cigarette holding chamber is specifically designed for the end user's brand and model of E-cigarette and is engineered to fulfill a wide range of application requirements. The eSTEP can be easily adapted to work with any combination of cartomizer (tank) and battery regardless of style or size.

The device's operation is simple and intuitive:

  • The E-cigarette is first manually loaded into the holding chamber
  • Next, the user selects their desired puffing protocol (CORESTA protocol, custom protocol, ect.)
  • Finally, puffing begins while an optional air driven actuator (for button activated types), triggers the E-cigarette so that it is perfectly synchronized with every puff

The eSTEP utilizes positive pressure puffing which is very attractive for analytical applications that require non-aged E-cigarette vapor to be sampled right from the mouthpiece of the smoking device. The user can select a pre-programmed CORESTA vaping protocol or create a custom protocol. This custom vaping protocol allows the user to adjust the puff length, puff volume and puff period all from an intuitive, push button display.
