Wondering if anyone has any input on this device. They say they test within +/- 2% when compared to laboratory HPLC analysis results. Sounds interesting but curious as to the science behind it.

Purpl Tester -- Anyone have experience?

Anyone used the Purpl tester? I’d like to use it to ‘pre-test’ large, multi-million pound lots of bio before I pay a lab for potency analytics on 100+ samples. I understand homogenization is required and you should take an average of ~5 tests.
