I find it hard to believe there isnt a lab supplier in the EU that will sell you a leybold or alcatel pump. Check gov surplus or university surplus if that exists in your area. Bidding websites.

Should this Pump do?

My pump has number 3x10 -1 but high on the ten.
Makes no sense for me i try to go for a new gauge.
Thanks so far :slight_smile:

no its a fire blanket will this do?
I though because its anti fire :slight_smile:
but please advise me if not
Thanks

thank you so far! i will change setup @Lightbulb

both was 2 liter but the flask dont fit well in the mantle and the matle getting to hot so it start to smoke.
I will get new flask and mantel now.
Thank you for the temperatures

and how can i prevent leaking in the part with the thermometer?

thanks so far!

You want a rotary vane pump like this

you can go as big as you’d like, it makes for an easier vacuum down but at higher expense. D8B is quite small but should work, a D16B would be decent and anything bigger would probably be a waste for your size.

Check out Alcatel 2021 or something too. Welch too

ok thank you sir!
i will watch out for theses Pumps.
Because these Guys only sells to Company i tried to buy.
Are they loud?

This one Welch is good one?

That looks like a diaphragm pump you are looking to get a rotary vane pump.

diaphragm pumps are good for stripping solvents/low boiling contaminates

Rotary Vane pumps are good for achieving super low vacuum for heads/main body fractions.

the rotary vane will do it all but the diaphragm pump will have a hard time achieving sub 50Mtorr vacuum.

That pump isn’t even close to big enough for what you are doing

Google edwards 28

That pump is a terrible shit, I dubth very much you are getting 10 microns in the system with that.

36

I have gotten 8 microns while all the operation with a cheaper pump, but only in the first use, they are not meant for that and they get broken

The one he uses no way, not even in the first use.
VEVOR is a brand that I don’t know how exists.

37

The distance of the pipe from chiller to pump is excessive, you are losing microns in each inch for no reason
