bell jar base plate

Post by RosalieL »

I know bell jars have come up many times before but I can't find the information I'm looking for.

At my previous school, we had a bell jar plate that was plastic but had a rubber seal in a groove that the bell jar sat on. It also had a tap to lock it after creating the vacuum so you could turn off the pump and slowly let the air back in and the bell would get louder. I am hoping to buy one like that for my current school but am having trouble locating it anywhere. I'm hoping someone has purchased one recently or might remember seeing one in a catalogue or when searching online!

Any suggestions on where I should look? Or alternative set-ups that do the same thing?

Oh, and I'm also looking into the oil free pump from MTA (Product Code LION1052060). Any feedback on those?

Thanks!!

We purchased one of these recently for a few of our different size vacuum jars, works really well.
