Some grain analyses require a very small sample. However, it needs to be representative of a much larger quantity of grain. The design of older dividers forces users to divide the sample in multiple steps which takes time and influences accuracy. The SPD 4200 can be used to sample rice, wheat, barley, rye, canola, oats, and other grain types.
The SPD 4200 single-step divider separates a representative sub-sample from a larger quantity. Consisting of 5 divider sections that each split the sample into 2 halves, the SPD 4200 separates a 3.125% sub-sample in less than 15 seconds. Simply pour the sample into the top funnel and open the shutter to let the sample fall through the divider. When ready open the tray to retrieve the sample. If more than one sub-sample is required, simply pour the remaining grain back into the top to obtain another sample. The system is gravity driven and has no moving parts. The transparent divider sections make it easy to verify that no sample is remaining in the divider removing the risk of sample cross-contamination.
An application note and full technical article reporting sampling statistics are available on the Perten web site and a video on YouTube.
