Ryan Roy HTL (ASCP) in Manchester NH asks: >>We are getting a new CBG that recycles xylene , alcohol, and formalin. We purchase buffered formalin. Does anyone know if after recycling the recycled formalin would or would not need be re-buffered?<<
If you distill buffered formalin, the formaldehyde is going to distill over, but not the buffer phosphate, which will remain in the still pot. I suppose you can buy phosphate mixtures to make Lillie's neutral buffered formalin anew, using your recycled formaldehyde. I think you also have to measure the concentration of formalehyde in the distillate, and dilute accordingly.
