Signal drifting/EM signal/Faraday cage/metal box with connector

Hi,

I am using a evaluation board to measure extreme small differential capacitance on the aF scale. I always got a drifting output, although the speed of drift is slow. I think this might due to the influence of environmental EM signal. I want to use a faraday cage to isolate the EM signal. The faraday cage is better to have connectors on it. I used to see somebody else use a metal box with connectors on it, but I don't know how it is called. Does anyone know where can I buy such a box or what it is named? I didn't find any item by typing faraday cage on DIGIKEY.

Thanks,
 
How big does it need to be? Basically anythink like a cast aluminium or box should work fine. You might wat to get an RF gasket as well to connect the lid nicely.
 
Searching for "boxes" on Digi-Key and selecting only the metal items (which can serve as Faraday enclosures), gives you this.
