AMS 210.08 Bottom Nut

AMS 210.08 Bottom NutBrief DescriptionDesigned to be driven into the soil opened for sample extraction and removed for subsequent use. The AMS Retract-A-Tip is a survey tool for collection of discrete soil vapor samples below the ground surface usually at discrete depths. The sampler is 300 series stainless steel with a 400 series stainless steel drive tip. It may be driven to the sampling depth using an AMS slide hammer or electric rotary hammer. The Retract-A-Tip is usually connected to the surface with fluoropolymer tubing. The sampler is opened by retracting the gas vapor probe extension string an inch or so. When open the sampling ports protected by a mesh screen are exposed. After collection the sampler may be closed by pushing down on the drive string.
