The attachment shows our oil-free pumping system "TSH 071" from 
Pfeiffer. In this picture it pumps just one holder, but will be 
extended by adding more T-tubes and valves in a dedicated stand to pump 
several holders. The improvised connection to the tubing is tight. 
Nevertheless, our workshop is currently building a dedicated, clean 
connection. We pump the holders to 1*10-6 mbar with this, measured 
where the gauge is in that picture.
