Unijet II Refrigerated Aspirator
« on: June 21, 2004, 06:24:00 PM »
Would someone kindly tell me anything they know about this Unijet II Aspirator?  Is it suitable for any of the applications described in the 'literature'?  Description states that a final vacuum of 4 mbar @ 4C water temp. can be achieved...  Thanks in advance!

I got the one with refrigerated water,
it boils water at slightly less than 40 Celsius. I think it's about 27-28 inches hg. Safrole should come out at 140-145 C.

It's a bit far from the specified 4mbar, theorical value. But looks good for most application you'll found here at the hive.

This thing is simply a water pump with two aspirators that recirculate cold water, so this should work without any problem unless you need a real strong vacuum. One nice thing about it is that you can use is to cool water for condenser or flask without having to use the vacuum head. In fact you just remove the pump head for that.
