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.
