The RD80 Volatile Acid Still is an improvement on the Cash Still for determination of volatile acids in wine. It features an aspirator pump to remove the spent sample, which speeds testing, saves water, avoids repair bills, and prevents cross contamination of samples. The R&D SO2 Apparatus uses the AerationOxidation Method to maximize testing accuracy. It is specifically designed for this test in consultation with enologists. Flexible spherical joints and interchangeable flasks facilitate simple operation and minimize breakage.
