Product Stability Testing

For over 15 years, Enthalpy Specialty Labs has assisted clients with short-term and long-term stability projects for all nicotine products from cigars to e-liquid.


Our extensive program offers on-site and off-site storage facilities that are fully validated, continuously monitored storage environments for ICH and WHO test conditions for both temperature and humidity control.

Enthalpy Specialty Labs offers stability testing encompassing various sample storage conditions for the evaluation of e-liquid and e-cigarette product lifetimes. We can also support study design and management of forced degradation studies to assess the “stability-indicating” power of the analytical methods under development for stability testing.

We remain a project-oriented laboratory, which makes us an invaluable resource for product stability testing. All stability projects are managed by a primary Enthalpy project manager with an assigned back-up to ensure schedules are never compromised and clients have a singular point of contact. From stability time points that range from weeks to years, Enthalpy has assisted manufacturers, regulatory agencies, and academia with tobacco and aerosol stability projects.
