Hi Paul... I'm importing 100L of TEA from China... don't think I need that much (510 Pyro)...so if you are interested, let me know... BTW: US$2.80/L (98% analytical grade)... I couldn't find a local supplier THAT cheap I.E. Thermo Fisher want NZ$54/25g + GST!!!
I've also ordered 10Kgs of Pyrogallol too.
Cheers
Mark
