I dont think this little guy can cut the mustard. Even with a repair and recharge, set to -50c, she is bottoming out at 16c.
I think it’s a 1.6l recirculating heater/chiller. Vwr 1166d.
Using for my 5L rotovap. Not as great results as using tap h20. All tap h20 goes back in the garden.
Vwr 1166d recirculating heater/chiller
Just had it serviced.
Set to -50c
16c-17c temp stable for the last 3 hrs. I think it needs to be alot colder for a much faster thuroughput.

this kept a line of rotos and the entire 5 station benchtop happy for me. With glycol running you can get her down -10c .
i purchased the dyf 5/10 from leakphan for $900 with shipping and it leaked out all its refrigerant in 10hrs of use, it did work good before a copper line ruptured, then i purchased the poly science 7L -20c from best value and that seems to work good with my roto but ive only tried the water bath at 30-35c.
i let it get down to -16c and then ran for 3-4hrs with roto bath at 30c. it climbed upto -4c and then stayed for the rest of the time. i think next chiller i would make out of an ac or mini split unit like others have done.
Really all I have in uses space is a dust bin liner as tank 8" round 3 feet high insulated with 1" foam
And the evaporator standing inside
Lines go treu the roof outside to compressor a pond pump and that’s it not much space involved
