Automatic Distillation Apparatus AZA1341

The Apparatus for Hydrogen Sulfide Tester AZA1314 from AZA Lab conforms to the ASTM D7621 Standard Test Method for the determination of hydrogen sulfide in fuel oils by rapid liquid phase extraction.

In this method, a weighed test sample is placed into a heated vessel containing a diluent base oil, where air is bubbled through to extract hydrogen sulfide gas. The extracted gas is then directed, via a vapor phase processor (Procedure A), to an H₂S-specific electrochemical detector, which measures its concentration in air and calculates the amount in the liquid phase in mg/kg. For Procedure B, the use of a filter cartridge is not required.

AZA LAB Sampling Cylinders & Gas Sampling Bombs are robust, high‑pressure vessels engineered for safe, reliable collection, storage, and transport of liquids and gases in demanding industrial environments. Available in single‑ended, double‑ended, and flat‑ended variants, they are constructed from premium materials like stainless steel (304/316 L) and Monel, offering corrosion resistance and durable performance . TPED, CE, and ISO certifications ensure compliance with international safety and transport regulations. Each cylinder features precision-engineered NPT connections (¼″ or ½″), customizable volumes from 150 cc to 10 L, and pressure ratings up to 5000 psig, making them ideal for applications in refineries, petrochemical labs, chromatographic analysis, and gas sampling in high‑pressure systems . Hydrostatic testing guarantees reliable integrity under rigorous conditions, while additional options—such as specialized valves, burst discs, dip tubes, and protective carrying cases—allow for tailored configurations to meet specific sampling needs.

The Semi-Manual Distillation Analyzer (AZA1286) from AZA Lab is engineered to deliver accurate, repeatable, and ASTM D86-compliant atmospheric distillation testing for petroleum products.
