Question

24. Split tube thief is used for sampling of
a) Homogeneous liquids
b) Particulate solids
c) Compact solids
d) Loose solids​

Answer 1

Explanation:

The split tube sampler is an apparatus for rapid undisturbed sampling at the surface. The apparatus is very suitable for research on root systems, fertilizing and soil biology.

Answer 2

Answer:

a) Homogeneous liquids

Split tube thief is used for sampling of Homogeneous liquids.

Explanation:

Two stainless steel tube halves with a working length of 40 centimeters make up the sampler. When removing the sample from the sampling tube, undisturbed sampling frequently presents a challenge. However, with this kind of sampler, both parts can be easily separated. In the detachable tube, the sample can be found (free or in a liner).

• The split tube sampler is simple to open for on-the-spot analysis or for sending the sample to the lab.
• It is advised to decontaminate the apparatus after each sampling, depending on the nature of the research (to obtain representative samples). This sampler can be hammered because of the conical screw thread connection.

Applications:

• Description and classification of soil profiles
• Sampling the soil above the groundwater table
• Soil environmental research
• Non-intrusive sampling
• Research on soil texture Root zone sampling
• Set includes
• Sampler with split tubes
• foil samples (10 pieces)
• An example of a transport container
• Nylon-head hammering head with impact-absorbing construction
• With chain and support, a spatula beam
• Cleaning supplies
• Robust carrying case.
