Hi
I have a vacuum oven to dry a project plastic tube 0.075in ID and 100in in length. Due to the material of the plastic I intend to dry it at around 80 to 120 degF in somewhere near 30 inHg.
1. My question is how to define dryness of the plastic tube? How long will I have to keep to dry out the entire water content in the tube? What kind of moisture sensor can I use inside the vacuum oven for this purpose?
2. Is it possible to take reading of vacuum gauge to find the deflection in vacuum pressure when there is steam and set a dryness standard instead of using moisture sensor?
3. What is a good position inside the oven for the plastic tube opening to be so that I can get faster rate of evaporation?
I understand the term "dryness" can not be justified properly. I will be doing KF titration after this process to further determine any trace of water.
Ultimate aim of the project is to prove the plastic tube is dry without the need of visual inspection.
Any help is highly appreciated.
Thank You.
