Thesand Bagfunnel

The Sandbag Funnel is the ideal tool for pulling construction materials for acceptance testing. It allows the sampler/person to get all the samples in the bag without any spillage, which is essential for a representative sampling. It makes it possible to extract a sample from a busy construction site in an expedited and accurate manner, But the Sandbag funnel is not limited to only construction materials. It works for a large array of materials.
