Leica 1520 cryostat: there is a crescent-shaped brass clamping part in the base of the blade holder assembly. It is similar to the one in the 1510, but different. This is the "brake shoe" that clamps the clearance angle position. Does anyone know a Leica part number for it? If Leica even sells the part.
Sakura Prisma stainer 6130 (6131) - does anyone know the part number for the newer loading door latch? Or an off-the-shelf make and model/part number and/or source would be even better. This is the newer version which mounts inside a small stainless steel housing and grabs onto a small plate on the inside of the loading door (not the older style that was all black plastic, with a small black plastic knob on the inside of the loading door).
I am working on a Thermo Fisher / Thermo Shandon CryoStar NX50 HOVP cryostat.
Unit details: REF: 957170
The unit shows Error 004-007 – Window heating error.
I checked the heated window cable. It has four wires, and when measuring resistance between all wire combinations, I get very high resistance / many MO, basically open circuit.
Does anyone know what these four wires are connected to? Are they only for the heater, or are two wires for the heater and two for a sensor / feedback circuit?
If anyone can share the wiring diagram, connector pinout, or relevant part of the service manual for the heated window circuit, it would be very helpful.
I am also trying to confirm whether the correct heated window assembly part number is 625970.
