Re: Need help finding portable vacuum dessicator

From:"Garcia, Vicki {Core~Palo Alto}"

I use a Scienceware vacuum desiccator purchased through VWR.   It has a
vacuum retention valve and will hold vacuum for 24hrs. 
It is made of polycarbonate on top and polypropylene on bottom.  The
methylmethacrylate fumes will eventually cause the top to 
crackle but it will still work.  This desiccator comes in three sizes.  Hope
this helps!

Subject: Need help finding portable vacuum dessicator

I need a purchase source for a good vacuum dessicator that has a control
stop cock to allow pressure in and shuts it off to maintain pressure.  This
dessicator will then be place in a 4 deg C fridge for a number of days.  I
hope to maintain the same vacuum pressure all through out while in the
refrigerator.  Any ideas? (a source will be nice).

Boring a hole in the fridge to maintain pressure is not an option.  I will
be using a plastic/monomer organic solvent(Methyl Methacrylate) in the
dessicator.  It needs to be under vacuum pressu
