the setup you’re after is referred to as “full bore”

eg Upgrading SPD to full bore - question regarding joint size. - #2 by Dr.stanky

see :5L Full Bore SPD? Input Appreciated - #3 by Kingofthekush420 for pictures.

and if you haven’t gone through some of the SPD hand holding threads, I suggest starting with I make terrible distillate....why?

the vacuum pump you have, while a very nice pump, is not really the correct tool for the job. ideal would be a dual stage rotary vane pump. see: Oil-Free Vacuum and Dry Vacuum Pumps

an Edwards E2M28 is the “gold standard” on this sized rig, and a used Alcatel 2021i is the budget approach.

the advice @greenbuggy gives is sound.

Though the sealing elements of the various brands of “dry scroll” pumps may be dry and not actively lubricated, the bearings that the scroll faces pivot upon are packed with grease and excessive solvent coming across will cause them to fail sooner rather than later.

I’ve posted pictures around here somewhere of an Agilent dry scroll that pulled rotovap & Buchner duty and died early from the liquor it was forced to inhale.
