To take a sample with the punch tool, gently press down onto the card with the metal cutting tip until the punch is taken. A twisting motion will help.
The plastic backing stops the punch from making holes right through the card and will reduce contamination.
Expel the punch(es) into a PDQeX cartridge using the plunger.
For DNA extraction, one to four 3 mm punches can be used.
