thank you for answering I asked this because I want to make something simillar to vacuum insulated panels, something like a plastic honeycomb core and then create vacuum but now I see that is not simple as I thougt it would be and defineatly much more expensive

what kind of a pump is used in creating vacuum in vacuum flasks or thermose. Diffusion pump, Roots Blower, Rotary vane pump
