Aqua regia gold refining tumbler

The IAO/BR25 system is a state-of-the-art solution designed for refining gold alloys using the aqua regia process. It offers a quicker, more flexible, and highly user-friendly approach compared to traditional static glassware units. Featuring a PPL tumbler with a total volume of about 50 liters and a useful capacity of 25 liters (acids plus gold grains), the system utilizes a motor-driven rotation that forces gold grains to continuously rub against each other, drastically reducing the overall dissolution time. To maximize efficiency and environmental safety, it is equipped with a Pyrex glass condenser that condenses acid fumes released during the process, resulting in a much more efficient fume
