In my experience low vac mode is not really useful for soft biological tissue, but good for mineralized one.

I think that it depends, low vacuum mode is not that good for high magnifications (in general, not only for biological), and some table top SEM operates only with low vaccum mode, which means you're a bit limitated. You should also check if the table top SEM comes only with backscatter detector, or only SE detector or both.

Could you please specify your needs? And then we can help you!

Thanks for your response. Our requirements are biological cells/tissues and hydrogel, polymer nanofiber (200nm width).

in a non conductive mode, with the resolution of 100-200nm, what are the best available table top SEMs?

Thanks

Hey @Narayanan check this one https://www.phenom-world.com/desktop-scanning-electron-microscopes/phenom-pharos

It's a FEG desktop SEM (since you need nanometer scale), I think you should also check about the detectors available in the SEM, check about the chamber size and etc.

Don't forget to give us a feedback! Hope we helped you!

@ Bindu Salim , Thanks for your suggestion

PSGIAS has this machine, you may visit and understand if this one meets your requirement

sure, Thanks
