FAQs of Riffle Sample Divider:

Q: How does the Riffle Sample Divider ensure accurate sample splitting?

A: The Riffle Sample Divider uses a series of precision-cut slots (fixed or adjustable between 10 mm and 25 mm) to evenly distribute bulk material into multiple collection pans. This mechanism ensures a representative and unbiased sampling, with typical division accuracy within 2%, ideal for laboratory and quality control applications.

Q: What types of materials can be processed using this sample divider?

A: This equipment is suitable for splitting a wide range of powder, granular, and bulk materialscommonly soil, aggregates, cement, and various laboratory test samples. Its adjustable slots and durable construction make it versatile for different sample types in laboratory environments.

Q: When should a laboratory use a riffle sample divider?

A: A riffle sample divider should be used whenever precise and representative sample subdivision is required prior to analysis. It is particularly necessary in routine soil, cement, and aggregate testing to ensure that all portions of the sample accurately reflect the whole.

Q: Where are riffle sample dividers typically used?

A: These dividers are predominantly used in materials testing laboratories, research facilities, and quality control departments involved with construction materials, soil science, or industrial powders, including cement manufacturing and mineral analysis.

Q: What is the proper process for using the Riffle Sample Divider?

A: To use, load the sample into the top of the divider. Operate the manual handle if present, allowing the material to pass through the riffle slots. Collect the subdivided samples in the supplied pans below, alternating between them for true representativity. The device is portable and easy to clean after each use.

Q: What benefits does this sample divider offer compared to manual hand splitting?

A: The riffle sample divider minimizes the risk of bias and human error inherent in manual splitting. It enables quick, standardized, and accurate sample division, improves repeatability of results, and ensures compliance with international standards such as IS 1607 and ASTM C136.
