leaf sample collection steps
Identify and cut cotyledon from the plant. Place this sample sample BETWEEN THE PLASTIC COVER AND ROUND FILTER PAPER.
CLOSE THE PLASTIC Cover then place on solid surface.
USE A COIN OR Blunt OBJECT TO CRUSH SAMPLE through THE PLASTIC FILM UNTIL the sample bleeds through BOTH SIDES OF THE FILTER PAPER.
REMOVE LEAF REMNANTS LEAVING BEHIND ONLY WHAT WAS ABSORBED BY THE PAPER.
PLACE Sample INSIDE THE ENVELOPE. CLEAN YOUR TOOLS, including the object used to crush your sample.
DO NOT SEAL ENVELOPES. SIMPLY CLOSE FLAP AND RUBBER BAND BUNDLES OF ENVELOPES ONCE YOU'RE DONE.
