Does it keep the vaccuum unassisted for a period? I want to use it to evaporate liquids in low temperature and low pressure.
This fluid extractor is designed for manual automotive fluid extraction, not for scientific laboratory applications such as sustained low-pressure evaporation. While it can create a temporary vacuum to draw out oil, the vacuum seal is not intended to be held indefinitely and will gradually dissipate over time.

Does it keep the vaccuum? I want to keep a gentle vaccuum in a desiccator and use it to evaporate water and alcohol at low pressure and low temperature. An ordinary vaccuumpump is not gentle and does not like alcohol vapor.
Does the extractor have a security that automatically stops extraction as soon as capacity is reached.
Do I need to pump permanently to extract oil or do I create vaccum in pumping like 15 times ?
