How do I determine the condition of the sampling kit?
- Check the tube (for signs of piercing or impurities such as traces of liquid or dust)
- Check the connectors (for warping, piercing or cracks)
- Check the needle (ensure it is straight, does not move between the needle and the connector, or is not warped)
- Check the filter (for warping and ensure it is white, stain and dust free)
