Formaldehyde is readily soluble in water and is commonly distributed as a 37% solution in water; formalin, a 10% solution of formaldehyde in water, is used as a disinfectant and to preserve biological specimens. And also Mix 1 part of formaldehyde solution min. 37%, Cat. No. 103999 with 9 parts distilled water or buffer solution (dilution 1:10).
