Hi Arnost,
Our pumps can go down to 25 micron/0.025 Torr which is not as close as you need. The chambers themselves have been tested and routinely operated at 25 micron as is typical from dual stage rotary vane pumps. We have not tested them down to 0.001 Torr although structurally I can see no reason why the chamber would not hold such a level of vacuum assuming the seal is in place properly.
At that level of vacuum, even the tiniest hair or piece of dirt might be enough to breach the seal to a detectable level, although this depends on the ability of the pump you have and the measuring equipment you have. You would also need to ensure all the connection joints are perfectly sealed. You may choose to fit higher grade fittings and almost certainly will need a better gauge or sensor to monitor the vacuum level as our gauge simply cannot read at that resolution.
