Vacuum prep and installation - parts have arrived |
|
|
The two parts needed to complete the vacuum assembly (ELOG 70) have arrived.
- (10) 5/16"-24 x 1 3/4" threaded rods - for attaching the turbo pump reducing nipple to the CF 4.5" gate valve;
- (1) 45 degree CF 2.75" elbow for attaching the calibrated Ar/He leak to the chamber.
I left them laying on top of the ultrasonic washer. They both need to cleaned and baked following the standard procedure for stainless steel, as the threaded rods are visibly dirty. |
