Hi Uday, I would simply ask Oxford for advice, I have never regretted asking them (or most others) for advice. On their web site it is written that the Desktop Cooler only goes down to 170K, so that will not do, I don't think. In fact, they only make two suggestions when you go through their product selection process and neither one of those is very small.
We are very happy with our Oxford system (used for protein crystallography) but small it is not.

Does anybody has some suggestions in this regard. Would be nice if someone has some information regarding the use of Oxford cryosystem Desktop cooler for protein crystals. Thank you
