HOW TO USE:
1. Hold the nylon hose and slowly push it into the quick-change connector hole on the needle valve body, and then insert it firmly into the end. After inserting it, gently pull it out to confirm that it cannot be pulled out.
2. Connect the soft nylon tube to the vacuum source.
3. Put into the PP separator and sample as needed.
4. Put an O-shaped sealing ring on the outer cone of the upper mouth of the base, cover the upper cover, and then vacuum (hold the upper cover with your hand when vacuuming, and release it when the vacuum is slightly higher).
5. Remove the pipe installed on the quick-change connector:
(1) Push the flange end face of the blue release sleeve completely and evenly onto the quick change joint.
(2) While pressing the blue release sleeve, pull out the test tube. If the release sleeve is not sufficiently compressed, the hose cannot be pulled out.
(3) For pipes that are repeatedly loaded and unloaded, if the head of the pipe is severely worn and scratched, please cut off the blocked part before using it again.
6. Take out the sample: manually unscrew the valve and release the vacuum.
