The Zone PTFE all-layer sampler is used in sampling to collect a representative all-layer sample from three different layers. Suitable for free-flowing powders and small-grain granulates.

The JN Sciencetech Double-Tube PTFE Sampling Probe is used for sampling fertilizers, foods, pharmaceuticals, and other similar granular materials. Also used for plastics, these probes conform to USFDA specifications.

They are constructed from extra heavy gauge PTFE tubing for durable, time-tested sampling. Open-ended probes without partitions and also with partitions are more convenient to empty and are widely used by grain elevator operators for obtaining samples from containers, gunny bags, Fertilizer bags, and truck loads. After a sample is obtained, the probe is held upright, and the sample is dumped from the handle.
