INSTRUCTION SHEET FOR SAMPLE BAGS
1. Label the bag with sample
information if necessary.

2. Tear off the top of the bag along
the perforation. 

3. Use pull tabs on each side to
open the bag. Sometimes a little
pull on the bottom of the bag
helps open it completely.


4. Put sample, liquid or solid, into bag.
Leave enough space at the top for
closing and mixing if needed.


5. Pull the ends of the wire to close
the bag. Holding the bag by the
wire ends, whirl the bag three
complete revolutions to form a
leakproof seal. Whirling the bag
will form the tightest seal. Larger
bags can be closed by “folding”
the tab over as tightly as possible.

6. Bend the wire ends over onto the
bag to complete the closing.
