There is a web site that has a lot of refrigerators and freezers. It's actually a lab supplier
www.bestlabdeals.com. Maybe you can find what you are looking for there.
You should be able to find out who is on contract for you in your Premier website.
We recommend GEM. We are VHA/Novation, but have used GEM and in our pharmacy remodel are using one of their pass-thru refrigerators as well. www.gemref.com
