Universal Vaping Machine

Our machine is able to replicate real-world, human puff profiles recorded with the Gram smart vaporizer.

Gram's universal vaping machine is indispensable to any experiment that requires smoke, vapor, or aerosol produced under consistent, repeatable conditions.

Similar to a linear smoking machine, Gram's universal vaping machine is built specifically to accommodate the nuances of vapor products. This machine is based on our own precision syringe pump design, which is capable of flow rates up to 45 mL/s and puff volumes of up to 100 mL.

This flexible and modular system can execute standard smoking regimens like ISO 3308, Canadian Intensive Regime (CIR), and CORESTA no 81.

But we're not satisfied with mere compliance with industry standards. Our machine is also able to replicate real-world, human puff profiles recorded with our smart vaporizer.

Since 2015, Gram Research has been recording dynamic vaping topographies from real users in the real world and playing back their usage with this precision laboratory instrument. Together, the Gram vaping machine and the Gram smart vaporizer form a powerful and comprehensive vapor research platform.

Modular hardware for maximum flexibility

The Gram universal vaping machine features a precision syringe pump and a three way directional control valve. After the syringe withdraws an inhalation, the valve switches and expels the aerosol through a third 'exhale' port.


According to your experimental application, the exhale port can connect to your choice of apparatus:

Applications include characterizing and benchmarking vaporizer device performance; capturing and analyzing smoke, aerosols and vapors; generating and exposing animals and cell cultures to consistent, repeatable doses of smoke or vapor; and more.

Powerful, intuitive control software

Gram gives you complete control with our desktop PC software.

Set pump speed, duration, rest intervals, vapor power settings, number of puffs, and more with the graphical user interface. Create and save custom testing regimes with the click of a button.

Test any vapor product

If it produces smoke or vapor, you can test it with Gram.
Gram's Universal Vaping Machine is compatible with all manner of vaporizers and ENDS. Various power sources - like common consumer vaporizer batteries, and heat not burn (HNB) products - can serve as independent variables in certain experimental applications.
Power to atomizer directly supplied by Gram vaping machine
Power to atomizer supplied by consumer vaporizer (mod) battery.
The nature of the power applied to any one atomizer has a direct effect on aerosol delivery and composition.

Power as an experimental control

‍How do different power settings affect the output of a vaporizer?

Gram makes it easy to answer this question by giving you control of the vaporizer's power source - directly or indirectly.

According to the software parameters you select, the Gram system can supply a regulated and user-adjustable 5.0 volts (up to 3.0 amps) directly to any vape cartridge or atomizer. Dial the power and down at will - you're in complete control with Gram.

Or, use a button-pusher accessory to evaluate a consumer vaporizer battery or variable voltage mod.
