Does anyone know who manufactures or distributes the black plastic compression fittings (with white ferrules) with the "Z" logo, which are used in Sakura VIP processors for connecting 6mm and 8mm tubing to R-1/8" and R-1/4" pipe thread?

When power is switched off or disconnected, on a VIP 5, it generates an EC 3 ("Power Outage") and an EC 7 ("Power is interrupted"). Does anyone have insight into the difference between the two codes?
I have a client whose VIP 5 generates EC 3 (without an EC 7) errors for no discernible (so far) reason. Has anyone run into this before, where it is generating EC 3 errors? Or does anyone have an idea of what could be the cause? The power supply voltages on the main board all seem stable (but I haven't been monitoring them at the time when the error occurred). The instrument is grounded, and no other equipment seems to be having power issues.

Does anyone know the details on  " error code 341- Retort Lid Sensor error". It appeared once, we stopped the program, started it again,  and it completed its run successfully. We just had a PM done on the processor the previous week. It seems to be running fine now  but I would feel more at ease if I knew why the error occurred and how to prevent it from stopping another program run in the future.

Does anyone have a PM procedure, PM checklist, or a service manual for a Milestone KOS tissue processor?  I have a couple of customers who have this unit. They aren't currently reporting a problem, but would like to have them PMed.

I have a vip6 that displays level sense errors when attempting to start a clean cycle. Process completes with no errors. When inspecting sensors I find paraffin buildup around sensors. Temps are within ranges. Any ideas?

Hi, the technical service of our Excelsior ES (built 2009) has been suspended and we are trying to fix a leak of the flush reagent bottle 2. leak appears in bottom of the instrument upon returning the liquid from incubation chamber back to the storage bottle. liquids from previous steps and other compartments, e.g. the xylol range, showed no leakage. 

visual inspection of the the hidden bottles section (not taking our any bottles): neither bottles nor the pipes or valves showed any leakage. in the front storage compartment we could not find any leak either. 

we would appreciate any help and suggestions you may have, many thanks, Melanie

Hi, 


We're receving this Failure. " There has been a heater failure. Retort triac failed." But triac is good, temperature sensors looks good, thermal fuses are good and with this failure message we cannot do anything on the equipment.


Anybody can help or share the service manual?

Is it possible to include Bottle 7 in this program if they are all alcohol? It seems to only let me include up to bottle 6 even if it starts on bottle 2.

That image is for a Sakura Tissue Tek Xpress X50 Tissue Processor, not a rotary tissue proccessor. I noted this back in 2020, and still it hasn't been corrected. Furthermore, the thumbnail is for a rotary microtome, not a tissue processor at all.
Could somebody fix this, please? I get the feeling that there is no one at home, at MedWrench. I am so disappointed.
