Extension rod 1 mtr. Long and 37.5 mm diameter – 5 Nos.
Jarring link (Large) for driving samplers 50 mm, 100 mm or 150 mm dia. This can be connected to the sampler or to the extension rod.
One eye hook, one wax container, one Methylated spirit stove, One wax laddle, and one pair of spanners complete in carrying case.
Accessories : Samplers :
Samplers for undisturbed sampling are available in different sizes. These are used with sampling outfit. Each sampler is 45 cm. long and is supplied complete with two end caps, cutting nose, driving head with air outlet valve and 3 Nos. C-spanners. Samplers are available in 50 mm dia, 100 mm dia & 150 mm dia. Thin walled samplers are also available in diameters 50 mm, 75 mm and 100 mm. Each sampler is 60 cm long and its cutting edge is hardened. These samplers can be used with sampling outfit ‘A’ drill rods b using suitable adoptors.

EXTRACTOR FRAME UNIVERSAL
(HAND OPERATED)
Designed to extract specimens from almost every type of sampling tube and mould used in solid engineering laboratory or in the field. It can be mounted vertically or horizontally as desired. It has an unique feature that three 38 mm dia sample.
Specifications : Comprises of a frame designed for screw jack operation, one each of the adaptor plates and plunger adaptors for 38 mm, 75 mm, 100 mm, 150 mm diameter specimens and a stand to obtain simultaneously three 38 mm diameter samples from one 100 mm diameter sample. The adaptor plate which slides along with the slotted supports can be claimed at any desired position by means of locking nuts. L Besides this, the tube or mould can be held in position by raising the tube guides and held in position with locking screws. The lead screw movement can be stopped at any predetermined position by tightening the lead screw collar.
Plunger adaptor for 200 mm dia samples
Adaptor plate with 200 mm dia hole and device to extract B number 38 mm dia samples..

DAMES AND MOORE SAMPLER
Highly useful for sampling soils. The sample collects into rings inside the sampler. These rings along with the specimen can be directly placed in a consolidometer cell assembly, thereby reducting the number of operations to extract the sample from a sampler, trimming to size and transferring into the ring etc. The possible disturbance in these operations is eliminated.
Specifications : The area ratio for this sampler is 81 percent and it meets with the specifications of sub-surface Exploration and Sampling of Soils for Civil Engineering Purposes by M.J. Hvorslev.
Consists of a split tube accommodating ten thing brass rings 60 mm x 25.4 mm long. A shoe with hardened cutting edge is screwed at one end. A driving head with ball check valve is fitted at the other end. The flaps mounted inside the cutting shoe prevent the cohesionless soil falling down while lifting the sampler.
Spares : Body consisting of osplit pipe threaded at both the ends and shoe.
Head Assembly : Set of 10rings 60 mm O.D. and 25.4 mm long.

PISTON SAMPLER
Useful for collecting undisturbed samples from soft to sift clay and sand.
Till the desired depth is reached the bottom of piston is kept flushed with the cutting edge of the sampler and on reaching desired depth only the sampling tube is forced into the soil keeping piston fixed in ground and then collecting the sample in the tube. The under pressure developed in the sampler while the sample tube advances, holds the collected sample.
Specifications : The outfit consists of Sampling tube, 55 mm, O.D., 580 mm effective length, Piston, one piston connecting rod 1 mtr. Long and a drive head with check valve and adaptor for ‘A’ drill rod.
Accessory : Adaptor for adapting a A type to E type drill rod.
