For proper sampling of powders, pellets and other friable materials which may become non-homogeneous in bags, this three zone sampler is invaluable.

Made of 1.9 cm (¾”) diameter anodized aluminum with a sharp stainless steel point; it has three ports 7.6 cm (3”) apart

The “T” handle is turned to close the sample cells, and the steel point is inserted through the bag wall. When the sampler is in deep enough to cover the three cells, a half turn of the handle allows samples to enter. The handle is then returned to the original position. The sampler is removed and the three samples transferred into containers for analysis.

The ports are 7.6 cm (3”) long x 1 cm (0.39”) wide with a volume of 9cc. The distance from the point to the first port is 4.3 cm (1¾”).
