Hi Ľubica, I don´t know any vacuum chambers in use for museum objects or publications from Germany the last decades.
Many years ago, a conservator in Germany used big steel chambers with high pressure (4-5bar) + high temperature (24-26°C) + low oxygen against wood boring beetles at furniture with good results in one week. For stored product pest control there are some practical experiences with vacuum bags. Therefore you have to measure the level of oxygen and pression inside the chamber during the vacuum. The level of vacuum depends of the material and construction of the chamber. Before you will use the vacuum chamber for museum objects, I would recommend a test with some “Dummys” and gazed insects to control the mortality. I think, high vacuum levels could damage fragile objects, like wooden carvings or sculptures (especially with pre-existing damages).
