Astoria-Pacific offers wineries a variety of methods for their analytical needs. Depending on the test, two different analyzers are available.
The Astoria®2 Analyzer has been configured to monitor Free Sulfite, Total Sulfite and/or Volatile Acidity. Free and Total Sulfite samples are determined using the DTNB method with Gas Diffusion Membrane. The working range for both Free and Total is 5 – 100 mg/L or 5 – 200 mg/L. Volatile Acidity is an in-line distillation method and is a good choice for laboratories requiring a true VA number, which matches CASH Still. Its analytical range is 0.012 – 0.12 g/100 mL. This instrument has been designed for high throughput, between 48 – 144 determinations per hour; and it is primarily recommended for laboratories with high sample volumes.
The rAPID™-T system is an affordable discrete analyzer for small to large-scale wineries. Astoria-Pacific’s wine customers use the rAPID-T system to analyze enzymatic and other colorimetric assays. The most common tests are: Acetic Acid, Ammonia, Glucose+Fructose, L-Malic Acid, NOPA and Total Sulfite. We have optimized and sell reagent kits for the above tests; however, the system is easily programmable to run various reagent kits from other manufacturers, such as Megazyme, NZYTECH, Randox, ThermoFisher Scientific and Unitech.
