[3dem] Service FEI Tecnai Polara (Sacha De Carlo)

[Grassucci, Robert]

Hi David,
As I recall Brandeis bought a straight F30 at the time rather than a Polara.  I know you are no longer physically at Brandeis but do you know if Thermo Fisher has stopped support for that microscope?  It would be quite disingenuous if they did not but will not allow us to have Tecnai support only on the Polara.  They are trying to tell me it is because of the version of Tecnai boards.  Just curious.
Bob

For many years we had our 100 kev microscopes serviced by a former FEI service engineer, who went into business for himself.  He did very well servicing instruments in New England.  His service contract was much cheaper than that of FEI and his fixes were less costly because, for example, he repaired the power supply rather than swap it out for a rebuilt one. Being a former engineer, he knew where FEI got its parts, and he collected parts from decomissioned machines.  I think his business was much, much more profitable than his salary at FEI.  I am not sure if this model would work for the more sophisticated Polara or whether a former Polara engineer could be found to set up his/her own company, but if it were to happen, it might take the combined pool of Polara owners to bring this about in the form of how many service contracts might be available and how much travel might be involved.

Planned obsolescence is a major problem for consumers, especially in a consumer society largely driven by companies that profit from intentional design limitations that hobble their own products.  Even in our field...  Are you suggesting this practice is one you espouse?

Or the Zeiss 902 that is sitting in every other pathology department in the world, that has required realignment only twice in the last 25 years, and still takes publication quality images every day.

It’s not quite fair to say the Polara is an F30, though.  It has a vastly different cryo-box, and cryogenic components including cold trap and anticontaminator, along with the different holder you mentioned.  It’s worth noting, that all of these components are in the objective region, and a failure in any one of them leaves you unable to operate. Then there are the host of microswitches, and interlock sensors that are not present on the F30s either.  It’s not that simple.
