Good to know, I am almost positive the pump isn’t strong enough to pull that deep vac, manual says ultimate vac is 10 mbar/ 7.5 torr. So I have a 6 cmf CPS and I will see if that gets it there.
Preach it mister! Damn those thermocouple adapters to hell!
I just pulled 10 micron on my 2L with two oring thermoadapters on the system, while messing around with some bump trap tech. Threw a little bit of vac grease around em and had no issues
I’m not saying it can’t be done, it’s just a less than ideal setup. Lots of issues come from mismatched probe size to o ring I.D. not to mention possible contamination from grease. I don’t use grease on any ground glass joints, just ptfe sleeves. All those warnings on the grease made me very wary of using it.msds krytox lvp grease artno 80005031 en.pdf (52.1 KB)
Here is the msds, the polymer fume fever caught my attention, especially as this as a smokeable product.
Where can the sleeves be purchased?
I get them on fleabay like this.
@Soxhlet You were talking about the ground glass joints I believe, not mantle sleeves. Are there ptfe sleeves for the glass joints or am I misunderstanding?
My mistake, I did not read far enough up the page.
Here is what you seek…PTFE SLEEVES 24/40 (3 pcs) | eBay
sorry… I was shooting from the hip!
All good! I saved the other link for some later day so it wouldn’t be a waste.
