Yes, they will definitely fit. I use Agamatrix meter, came with lancets so used them up. Surgery prescribes 33G. I didn't use them for long - went back to my preferred Fastclix. I confess I found them quite awkward to assemble/disassemble, probably because I have a noticeable tremor.
My insulin needles are 31G. In medicine, just in case you haven't come across it yet, needles of all types are measured **G. the smaller the number the wider the needle is. And the length is always with the gauge.
