Acker Drill Company Inc products

This widely used sampler is a heavy duty version of the standard split tube sampler. The Acker Drill Company developed and patented this split tube sampler which is better adapted to severe service under hard driving than the standard type...Coarse threads in the sampler head speeds assembly and disassembly...As with all other Acker tube style samplers, the shoe is Heat Treated to stand exceptional abuse. The standard length of the samples is 18" with 24" an option. Ball check feature prevents washing out sample on withdrawal from the hole.

This split tube sampler is designed for taking soil samples at the bottom of the cleaned bore hole by the drive weight method. The split section is held together with a ball check head and a hardened steel drive shoe. The ball check feature in the head prevents samples from being washed out of sampler upon withdrawal from the hole. The sampler is designed to accommodate a brass, plastic or paper tube liner for collecting and carrying samples to the field office. Two sample lengths are available. Note steps in tube design...Acker`s Heat Treated Drive Shoe is recessed to accommodate various accessories.

This sampler is designed to take undisturbed samples in cohesive type soils and clays.-.The thin steel tube containing the sample may be removed from the sampler head and used as a container to transport sample to laboratory thus avoiding any damage to sample or costly delays in operation. In practice several replacement tubes are carried by crew to minimize disturbance, preserve moisture and cut down on delays in sampling procedure. The thin wall tube is made available in either steel, galvanized or brass and in varying lengths. This sampler is also commonly called a "Shelby" or "Chicago" thin wail sampler. The procedure for taking samples is outlined under ASTM Standard Procedures, whereby the sampler is pressed into the undisturbed clay or silts by hydraulic force. Stainless Steel tubes Now Available to meet your environmental sampling requirements.

This sampler features a stationary piston, that is, the piston remains stationary as the outer tube of the sampler is pushed ahead into fine silts or clays. The piston creates suction on the sample assisting it into the sample tube. In operation, the piston closes the entrance of the tube eliminating any change of contamination in the tube prior to pressing. The sampler features a vacuum release and a cone clamp assembly that prevents the piston from pushing out the sample upon recovery. The outer tube, containing the sample, is generally used to carry the sample to the laboratory. Several replacement tubes and caps are desirable to take continuous samples without delay. The actuating rods are in convenient tengths for transportation and are necessary to hold piston during the pressing of the sample. For operation in brackish water, brass or stainless steel tubes are commonly used.

The Laskey Sampler was designed to recover continuous, relatively undisturbed soil samples when drilling with Hollow Stem augers and works similarly to the Acker Oenison Soil Sampler.

This type chopping bit is used to clean out material that has accumulated inside the casing. Water is pumped through the drill rods and out the ports in the bit to flush the material from the casing.

We have grouped together the various types of interchangeable parts and accessories for solid and split-tube type samplers. Since these samplers ate repeatedly driven into the earth, it is necessary to periodically replace them. Spate parts should be considered when placing order for samplers.

Heat Treated: This open shoe Is made from heat treated case hardened steel `or sampling coarse materials up to the diameter of the throat opening. The inside diameter of the shoe may be the same as. or slightly smaller, than the inside of the tube, thus making it possible to collect a good representative sample.

This inexpensive spring retainer is quite useful in collecting coarse sand and small gravel or unconsolidated type materials. The spring fingers gently press against the sample and hold it in until it is unloaded at the surface. The retainer fits in a slot already provided for it in the sampler show. Fingers are adjustable to improve sampling.

Basket retainers have flexible fingers that open to admit loose dry sand, then close, forming a tight lock, that retains the sample when the tube is removed to the surface. A slot is provided in the sampler show to accommodate the basket ring. Steel basket retainers have heat treated fingers that can be adjusted to improve sampling. Stainless Steel Retainers now available to meet your environmental sampling requirements.
