About
This new VapoMeter continues Delfin’s proven closed-chamber technology, trusted by researchers across cosmetic, medical, and academic fields. This method ensures accurate TEWL readings in normal room conditions, unaffected by ambient airflow. A new built-in skin temperature sensor adds depth to analysis. The core principle - measuring RH increase in a sealed chamber - is now enhanced with intelligent features that support consistent and user-friendly operation.
The VapoMeter is used to measure Transepidermal water loss (TEWL) which is a key indicator of the skin barrier function and the ability to measure this accurately is essential in a wide range of clinical and personal care applications.
It is wireless, fully portable and measurements are unaffected by the instrument’s orientation. The VapoMeter has been used in a wide range of clinical studies. Measurements take just a few seconds and accurate repeatable results are obtained at both high and low evaporation levels. A range of Franz cell adapters are available for in-vitro studies.
Claims
Measuring TEWL is an efficient way to test the skin barrier function. The skin barrier function plays a crucial role in maintaining overall skin health and protecting the body from external threats. VapoMeter is recommended to assess these skin features:
Skin moisturizing
Skin Ageing
Skin Acne and Blemishes
Erythema (Skin sensitivity)
Peeling skin (desquamation)
Roughness
Skin occlusion
Puffy Eyes
Chapped Lips
Pollution
Scalp sensitivity
Nail hydration
Delfin VapoMeter is also the Instrument of Choice for In-vitro Release Testing (IVRT) / In-vitro Permeation Testing (IVPT)
For in vivo applications, VapoMeter® VX is used to assess skin barrier function directly on living skin in dermatological research, cosmetic testing, clinical studies, and treatment evaluation.
For in vitro applications, one of the most important use cases is In Vitro Permeation Testing (IVPT), where TEWL measurements are used to assess skin sample integrity. By measuring TEWL from skin samples, researchers can establish objective inclusion and exclusion criteria and ensure that only skin samples with acceptable barrier properties are included in the study. This helps improve study quality and data reliability.
VapoMeter® VX can also be used in In Vitro Release Testing (IVRT) and other diffusion cell applications involving skin samples and reconstructed skin models. To support in vitro research, Delfin has developed dedicated adapters for VapoMeter® VX in collaboration with diffusion cell manufacturers, ensuring compatibility with the most widely used diffusion cell systems. This enables researchers to use the same TEWL measurement platform across both in vivo and in vitro studies, supporting consistent workflows and data collection.
