Certified Cylindrical Gas Diffuser Stone

Methods : ASTM D892, ASTM D6082

The Mott-certified cylindrical gas diffuser stone meets the certification requirements for the ASTM D892 & D6082 foam method.

The main benefits of metal diffusers are

• Uniformity – Cylindrical metal diffuser stones are typically manufactured with tight tolerances and have a smooth surface which provides a consistent and uniform distribution of gas bubbles throughout the oil sample. This leads to more accurate and reliable foam stability measurements.
• Easy to clean and maintain – Mott Metal diffuser stones can be cleaned easily, reducing the risk of contamination and ensuring that the test results are accurate.
• Hold specifications for a longer time than stone diffusers – The permeability and porosity of stone diffusers can change over time, which can lead to inconsistent test results. Metal diffusers, however, are not affected by changes in porosity and permeability, which means that they can be used for multiple tests without the need for frequent replacement.

It is important to note that metal diffusers, like any diffusers, should be tested periodically, preferably after each use, to ensure that they are performing as expected and that the test results are accurate.
