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

We developed a new sub-sampler. This will replace the current Crusher. 

The first step for a LiaB sample is to reduce the size for analysis. This size reduction is done before the drying process. 

This article explains the sup-sampler process. 

The subsampler consists of 3 parts. See the picture below. 

The three parts only fit in one way on each other.

Step 1: Empty the sample in the bottom part of the subsampler.

Step 2: Spread out the sample equally, if necessary crush the big particles into smaller parts and remove stones and roots. 

Step 3: Place the middle part of the sub-sampler on top of the soil and the bottom part of the sub-sampler.

Step 4: Make sure that the middle part is completely pushed trough the sample.

Step 5: Place the lid on top of the bottom and middle part. 

Step 6: Turn the sup-sampler 180 degrees. Now the bottom part becomes the top part. 

Step 7: Remove the top and middle part of the subsampler and you are left with your sub-sample. 

Step 8: check if the whole sample went trough the tubes. If necessary, push the left material trough the tubes.

Step 9: Place the sub-sample in a dryer part. the sample is now ready for the next step, drying. 

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