Description
The AZA 0981 Riffle Sample Divider from Azalab is a precision-engineered instrument used for splitting large soil and aggregate samples into smaller, representative parts. Essential for laboratory material testing, this device is a reliable solution to ensure unbiased sample division, especially when preparing specimens for sieve analysis, specific gravity tests, and other construction material evaluations.
Constructed from high-grade mild steel with a durable powder-coated finish, the AZA 0981 is widely used in civil engineering laboratories, construction material testing units, geotechnical labs, and field testing stations.
🔍 Why Use a Riffle Sample Divider?
Aggregate and soil test results are only as reliable as the representativeness of the sample. Improper sampling introduces variability, which leads to inaccurate test results. The riffle box method is widely accepted by global standards for its accuracy and repeatability. The AZA 0981 simplifies and standardizes this step.
It is particularly useful for:
-
Fine and coarse aggregates
-
Granular soils
-
Cement and powder mixes
-
Recycled construction material
🛠️ Design and Functionality
The AZA 0981 consists of multiple fixed-width chutes arranged alternately in two directions. When a bulk sample is poured into the top, it gets evenly split into two portions by falling alternately through each chute into two separate pans positioned below.
This equal distribution ensures that both resulting sub-samples are statistically identical, allowing you to choose either for lab testing and retain the other for reference.

❓ Frequently Asked Questions (FAQ)
Q1: Can this be used for fine sand and powders?
A1: Yes, if equipped with narrow-width chutes, the AZA 0981 is suitable for fine materials such as sand and powdered cement.
Q2: How many times can I divide a sample?
A2: The sample can be split repeatedly until the desired test quantity is obtained without affecting the representativeness.
Q3: Does it need calibration or maintenance?
A3: No calibration is required. Basic cleaning and occasional tightening of screws are sufficient for maintenance.
Q4: Is the AZA 0981 portable?
A4: Yes, it is compact and light enough for field use and easy relocation in labs.
Q5: What is the difference between a Riffle Sample Divider and a Sample Splitter?
A5: They function similarly. The Riffle Divider is the more manual, traditional version. The term “Sample Splitter” often includes automated versions or versions with specific slot sizes for standardization.
