| Sample splitter |
| A hopper which allows the sample to fall into a series of alternate-facing chutes which separate the sample into two equal portions in trays or boxes positioned below. |

Where a number of incremental samples have been taken and a large aggregate sample created, the sample divider may be used to reduce the total sample size. For example, 10 kilos of grain may be reduced to two equal portions of 5 kilos. Repeated use can further reduce the size of the sample until an appropriate quantity for the final samples is reached.
This quantity may be divided into two equal and representative portions to create the final sample and the duplicate or reserve sample. |
| The bottom of the hopper is divided into a number of fine chutes alternately facing left and right. When a powdery or granular sample is poured into the hopper it passes through the chutes, falling equally into the trays below and creating two identical portions. |
| Wheat, rice, sugar, grains, or plastic beads for further processing. |
| Remove the trays and wipe with a clean cloth. If dust or powder remains in the apparatus it may be necessary to wash it with hot water and detergent. Dry thoroughly before re-use. Preferably separate dividers should be reserved for food and chemicals. |
