[Histonet] Automated Coverslippers

[Morken, Timothy]

Jennifer, we have used the Sakura Glas, Glas2 (attached to prisma stainer), and now the Sakura tape cover slipper attached to the Prisma. Also we have had the Leica CV5030 glass coverslipper. 

All worked as long as they are kept clean. Daily maintenance is a must. If in a service contract they can last until parts are no longer available. 

However, we moved to tape once we started scanning all our slides. Tape coverslipping is much faster and it dries instantly, allowing scanning immediately.

The pop-off issues with the tape was solved 20 years ago, so it has not been a problem. The only problem we have seen is that the tape does get scratched if the slides are handled a lot outside of flats. Previous to scanning we pulled slides a lot for conferences so pathologists did not like it. Once we started scanning that became a moot issue - no one pulls slides anymore except for the rare send out consultation.

Subject: [Histonet] Automated Coverslippers

Hello Histonetters,
My lab currently has a Leica CV5030 that is attached to our ST5010 Autostainer. We bought it way back in 2012 and it is starting to have progressively more issues working reliably.  This is the only one that can be integrated with our stainer, so we know we'll have to get a standalone unit and transfer slides to a new rack.

What automated coverslipper is everyone using? I know in the past there have been issues with tape coverslippers popping off of the slides when stored long term, but has this been fixed with newer units? What is everyone's experience with them?

I got a quote for the Leica Spectra coverslipper, but I am not familiar with what other companies have available.

Thanks all,
