safety, read label and accompanying MSDS before using.

To order individual reagents or test kit components, use the specified code

number.
This test is designed to separate soil into its three basic mineral fractions:

sand, silt, and clay. The amount of time required for the soil particles of

various sizes to settle in the soil separation tubes forms the basis for this

test. From the amount of material collected in each tube it is possible to

determine the approximate percentage of each fraction as represented in

the original soil sample.
The procedure for preparation of the soil sample for testing is described in

the accompanying handbook, A Study Of Soil Science.
The separation tubes should be marked for identification in the following

manner: Mark the first sedimentation tube “A”, the second “B”, and the

third “C”.
PRO CE DURE
1.
Place the three Soil Separation Tubes in the rack.
2. Add the soil sample to Soil Separation Tube “A” until it is even with

line 15.
NOTE: Gently tap the bottom of the tube on a firm surface to pack

the soil and eliminate air spaces.
