                    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.
