Hello everyone,

I know that using ParaFilm or Nescofilm around ground glass
joints to prevent solvent evaporation is a big no-no in the
world of lipid analysis (and from experience I have seen why !)
but I wonderered if that fairly inert-looking PTFE tape*
could be used ?

Just a thought,
Jo

to produce at gas-tight seal
