I noted that a fairly new Leica 1520 comes with 315 grams of R452A refrigerant. Does anyone know if this will be the norm - will all of the cryostat manufacturers be switching to this refrigerant, instead of R404A (which is about to be phased out)?
I did note that it does still use a Danfoss SC15G compressor (which now has a sticker on it saying "R452A"). And, unfortunately, it also still has the double e-valve.

Leica CM1520 cryostat - looking for e-valve module p/n?
Leica CM1520 cryostat. I am looking for the current part number for the expansion valve module. I was told that the e-valve module from the CM1850 would work, but Leica says that both part numbers I have for that have been discontinued, with no replacement. I have been unable to find a service manual or parts list for the 1520. Reply

Leica CM1520 cryostat refrigeration
There are two solenoids behind the lower front panel (upper right) of the Leica CM1520 cryostat. One of the solenoids, I presume, is for the defrost circuit. Can anyone tell me what the second solenoid is for? Does anyone have a service manual or any service literature?Reply
