Petrolog/Sample File

Never rely on your memory to compare one sample to another. The Petrocraft petrologs ensure that your soil samples are kept separate from each other (preventing cross contamination) while still keeping them close enough to be easily compared. This way you can compare sediments where color and texture changes are subtle.

Always have your soil sample close-at-hand so that you can see how they’ve changed over time or from location to location. Grab a 10-compartment or 100-compartment petrolog today!
