REFLUX EXTRACTOR 4000 GMS AZA0941
The AZA0941 Reflux Extractor 4000 GMS from Azalab is a high-efficiency laboratory apparatus designed for the quantitative determination of bitumen content in asphalt paving mixtures using the reflux extraction method. Engineered for large sample capacities up to 4000 grams, the AZA0941 is an essential instrument for civil engineering laboratories, road construction quality control, and materials testing facilities.
By ensuring accurate separation of bitumen binder from aggregates, the AZA0941 helps verify compliance with asphalt mix design specifications, directly contributing to durable, high-performance pavement construction.
Description
Reflux Extraction Principle – Accuracy You Can Trust
The reflux method is a proven and widely accepted technique for bitumen extraction. In the AZA0941:
-
The asphalt sample is continuously washed with a suitable solvent
-
The solvent is heated to vaporization
-
Vapors condense in the condenser and drip back onto the sample
-
A continuous washing cycle dissolves and removes bitumen efficiently
This process ensures complete extraction with minimal loss of fines, resulting in highly accurate bitumen content determination by mass difference and clean aggregates suitable for further analysis.
Designed for Efficiency, Safety, and Large Samples
Safety and operational reliability are core to the AZA0941 design:
-
Closed reflux system minimizes solvent loss and operator exposure
-
Efficient condenser cooling ensures maximum solvent recovery
-
Controlled heating system prevents overheating and ensures stable extraction
-
4000 GMS capacity allows testing of large, representative samples, reducing result variability
The robust construction and stable support frame make the AZA0941 suitable for continuous laboratory use in demanding environments.
