Is polypropylene resistant to BSTFA and MTBSTFA?

[laplynn]

Hi, when doing derivatisation, do you use a glass syringe to transfer the derivatising agent or a disposable polypropylene micropipette tip? If a glass syringe is used, what solvent is effective in rinsing out BSTFA and MTBSTFA? Thank you.

Glass; methanol

Hi

I would fully agree with Tom.

For me it is not so much the PP tip itself but the concern about damage from the vapours to the micropipette seals.
