TKN Boling Stones
We use Teflon boiling chips and have no problem with the pumping during digestion.
That is what I have been using. I'm also wondering if possibly the flasks are too full of liquid.
Do you use the Labconco Micro-Digestion system? I'm adding 5 g of soil, 50 mL of standard and 10 mL of TKN-reagent. This is for my MDL study.
When I've added only liquid and less than 50mL I don't get the bumping problem.
