Exactly Duncan.
Folk in this lab used to buy off the shelf.

so I enquired:-)
Life tech have dT18 FS @ 55pounds for 25microgramme
Their custom synth folk can make you 2X that for 25pounds desalted. I
asked what was the difference and they say nothing it is only for quality
control.
I asked if the quality was any less and they said it ws the same.

Bizzarre.

Also MWG would do it for 10 pounds.

cheers
