Operating guide:
- Inflation pressure: Avoid filling pressure higher than 6000Pa. Fill gas until the bag is fully expanded, however, it is not so tense when you press it using your finger.
- Operating temperature: Working temperatures should be -60°C to +100°C for PTFE connector and -20°C to +80°C for PC stopcock valve .
- Storage and use: Keep away from flame and high temperature when filling and storage. Avoid contacting sharp stuff.
- Gas exchanging: Before use, flush sampling bags three times with the gas you want to fill.
- Needle sampling: When using a needle to draw gas from highly elastic septum, squeeze the septum with fingers in order to restore the sealing property after pulling out the needle.
