What type of pan is preferred for use with the splitter during sampling?

The preferred choice for use with the splitter during sampling is the hopper or straightedge pan. This type of pan is specifically designed to facilitate the efficient and even distribution of material when using a splitter. The shape and structure of a hopper or straightedge pan allow for easy collection of samples without risk of segregation, which is crucial for obtaining representative samples. This characteristic helps ensure that the material being tested reflects the actual composition of the whole batch, leading to more accurate test results.

Additionally, the design of a hopper or straightedge pan often incorporates features that minimize the likelihood of material loss or contamination during the sampling process, which further supports the integrity of the sample collection procedure. In contrast, other pan types, though functional for various other applications, may not provide the same level of efficiency or precision when utilized alongside a splitter.
