Customer Reviews

University of Glasgow Review by Chemical Biology & Medicinal Chemistry
We are really pleased with our Christ Alpha 2-4LD freeze dryer. It is an “easy to use” machine and just does the job that you want it to do. A nice feature of this freeze dryer is that it has a low ice condenser temperature (-85 °C), meaning that you do not need to setup a cold trap between the freeze dryer and pump when you have samples containing organic solvents.

We are a medicinal chemistry group from the university of Glasgow and mostly use this machine to freeze dry peptides or peptidic compounds. Since we design and make biologically active compounds we need to be sure that our “future medicines” are completely dry for testing purposes. And so, we really need a freeze dryer that is reliable and excellent in its job. That’s why we use the Christ Alpha 2-4LD freeze dryer
