Hi All,

Does anyone know if FEP can stand up to BABB?  The obvious test is to put
some tubing in BABB, but the corrosion could be slow enough that I can't
see it, and I don't want to contaminate the objective (lightsheet
application (and I do know this will be an optical nightmare)).

Thanks.

Hi Gary,
haven't tried it myself, because, what's the point? FEP has RI close to that
of water, so it does not introduce severe aberration when used for sample
embedding with water-based immersion media. In BABB a FEP tube would cause
bad aberrations (depending on tube dimensions and the NA of your objective
lens)...

But my guess is it is chemically compatible. FEP is similar to PTFE in many
respects, see here:

Hi Gary,

I don't think it matters whether it is or isn't.  FEP tubing has the same
RI as water.  If you put BABB inside (RI >1.5) you'll have too much
spherical aberration to see anything clearly.  Just re-hydrate the sample
into water and then place it in a microscope-friendly aqueous clearing
solution (RIMs, CUBIC-R, PROTOS, Optiview, SeeDB2, etc.)

Hi Gary,

The R.I. will be the issue more than the FEP tubing holding up against BABB.  If you need something to hold your BABB cleared sample then you should be looking for some kind of boro-silicate glass tubing as this will match up with the BABB a lot better (still not exact but better than FEP would).  I know Zeiss were talking up boro-silicate for use on their Z.1 as a way of sealing things like 3DISCO away from the sample chamber/objective.  I did track some down to a company in Germany who would sell various diameters and custom size the length for you.

Cheers
Mark
