PoreMaster eGaIn Filling Station

Anton Paar’s eGaIn Filling Station delivers the first mercury-free porosimetry method that fully matches mercury intrusion performance. Using safe, non-toxic eGaIn, it removes the health, environmental, and regulatory burdens of mercury while providing high-resolution pore size data without special infrastructure. With global mercury bans approaching, this unique solution offers a sustainable, future-proof path to precise in-house pore analysis.

Given its pioneering nature and specialized production, it will initially be released in limited batch quantities. Institutions aiming to lead in mercury-free porosimetry should act early to ensure access to this exclusive initial release.

Key features

Mercury-free performance

Anton Paar’s eGaIn porosimetry replicates the pore size range, resolution, and precision of mercury intrusion porosimetry (MIP) without using toxic materials. The eGaIn alloy behaves like mercury in its ability to penetrate and measure pores across the same size spectrum, ensuring comparable analytical results. Labs gain the same trusted data quality and performance while eliminating all health, safety, and environmental concerns related to mercury handling.

Safe and easy to handle

eGaIn is a non-toxic, environmentally benign liquid metal that poses no risk to lab personnel or the environment. It requires no protective gear, special ventilation, or hazardous material handling procedures. This makes high-performance porosimetry possible in any standard laboratory environment. The eGaIn Filling Station streamlines porosimetry measurements and removes the need for specially trained staff or complex infrastructure.

Ready for future regulations

With global restrictions on mercury tightening and potential bans expected by 2029, laboratories using mercury-based porosimetry face additional compliance challenges. Anton Paar’s eGaIn technology provides a future-proof solution that meets emerging environmental and safety standards. It enables users to stay ahead of regulatory changes while maintaining analytical excellence and operational freedom without hazardous substance protocols.

Flexible system upgrade

The eGaIn Filling Station is an optional add-on, designed to support both mercury-based and mercury-free operation. Labs can continue established workflows and transition to the new method at their own pace. This flexibility protects previous investments and offers an easy pathway to safer, sustainable porosimetry without sacrificing performance or data comparability.

Sustainable material use

Anton Paar provides standard operating procedure (SOP) instructions for recycling eGaIn from previous measurements. This ensures minimal waste and cost-efficient operation. By enabling repeated use of the same measurement medium, the system supports long-term sustainability goals and responsible lab practices, making eGaIn porosimetry a genuinely green alternative to traditional methods.
