The difference is that yours are not teflon coated while the ones used
here are coated (like the 3 layer SGE TCS series). The coated ones are
not so flexible and will therfore not seal a reactor which is too short.

I just used the septa which where already in use here in the lab.
For the next order I will check the price of the SGE.
Any experience how many injections can be performed on them?

Robert
