I was bottle washing in a marine bio lab in 1978. We used an Analar product to wash glassware which didn't measure dissolved phosphate levels and iirc Chromic acid for the ones which did. From memory, the colorimeter was pretty shit at phosphate anyway.
We did glass pipettes for everything and they were a royal pain to rinse until I rigged an automatic syphon made with a 2l measure and some plastic bits.
I went to work stoned and fell over carrying a week's glass back to the drying cab. I think I won the lab sweepstake for breakage value that day.
200 trips to the firth of forth seaside towns, one pair of gumboots, and a labcoat which was stolen the first week of uni in 1979. Coastal estuarine waterflow is fascinating.
