Pass through gelatin-chrome alum (0.5% w/v gelatin−0.05% w/v chrome alum, heated to 40°C and filtered). Wrap with aluminum foil and sterilize at 120°C for 2 hr (heating at higher temperatures can be deleterious for the coating). The sections are then stored at −80°C until fixation or are fixed immediately....

According to table 1, measure exact amounts of alum, Cr-alum, and deionized water in a 100 mL beaker Heat and stir the mixture until all solids dissolve, filter by gravity filtration
- A saturated solution of pure chrome alum will grow darker crystals, but the solution will be too dark to see through. Feel free to increase the concentration of chrome alum, but be aware that the solution becomes deeply colored.
- SOCOSURF A1858/A1806 is a REACH compliant chromate & fluoride free aluminium surface treatment. Etches & deoxidizes aluminium & its alloys. Airbus approved.
- Chrome alum is known as a double salt. If you mix solutions of potassium sulphate and chromium(III) sulphate so that their molar concentrations are the same, the solution behaves just like you would expect of such a mixture. It gives the reactions of chromium(III) …
