StainsFile Fixing agent - Working safely with picric acid
Picric Acid, Saturated Safety Data Sheet according to Federal Register / Vol. 77, No. 58 / Monday, March 26, 2012 / Rules and Regulations 01/30/2018 EN (English US) 2/6... To prepare this solution, a considerable amount of picric acid is required, which is an explosive. Federal and state regulations prohibit the storage of this chemical in the laboratory unless it is stored under water. We found that saturated aqueous picric acid could be substituted for the saturated alcoholic solution. Other changes were made to simplify the method. Mallory's method for fibrin

Acidify a dilute solution of picric acid (100 mL of 0.4%) to pH 2 by the addition of 2 mL of concentrated hydrochloric acid. Add granular tin (30 mesh, 1 g) and allow the mixture to stand at room temperature.
Stainsfile Picric acid
Since picric acid is usually used in aqueous or ethanolic solution, it is simpler just to measure the required amount of picric acid by volume, then dilute as necessary. The volumes are based on the amount of picric acid in a saturated solution. Below are the figures (taken from the how to heal open wound on face overnight Preparation of PICRIC ACID (2,4,6-trinitrophenol). 25 g of phenol and 25 g of concentrated sulfuric acid (d=1.84g/ml) in a round-bottom flask equipped with an air condenser are heated together for …
