How to use new sub-sampler for Lab-in-a-box

The subsampler is used to reduce the size of a soil sample before drying and further processing. Proper subsampling ensures that the final sample is representative of the original field sample. This article explains the sup-sampler process. which replaces the previous crusher in the LIAB workflow.

Subsampler Components

The subsampler consists of three parts, which fit together in only one way:

How to Use The Subsampler 

Step 1: Add the Sample

Place the soil sample into the bottom part of the subsampler. 

Step 2: Prepare the Sample

Spread the soil evenly. Break down large particles, and remove stones and roots.  

Step 3: Place the Middle Part

Place the middle part of the sub-sampler on top of the soil and the bottom part of the sub-sampler.

Step 4: Press Through

Ensure the middle part is fully pushed through the sample. 

Step 5: Add the Lid

Place the top lid onto the subsampler (on top of the bottom and middle part).

Step 6: Flip the Subsampler

Turn the subsampler 180 degrees. Now the bottom part becomes the top.

Step 7: Retrieve the Subsample

• Remove the top and middle parts of the subsampler
• The remaining soil is your subsample

Step 8: Check the Sample

• Check whether all soil has passed through the tubes.
• If needed, gently push remaining material through

Step 9: Prepare for Drying

• Transfer the subsample to the drying container. The sample is now ready for the next step, drying. 

• Note: The left over sample can be stored until the sample is fully analyzed.
