An alternative fixative to Formalin and Formaldehyde. EMS is proud to introduce an alternative to Formalin and Formaldehyde in many different applications. Our unique kit comes premixed and measured and ready to use. The kit consists of 2 vials: Solution A & Solution B (Absolute Ethanol, Glyoxal Solution, Acetic Acid and water).
Instructions: Add solution A to solution B. Vortex the two solutions together and bring to a pH of 4.5 with the addition of NaOH 1M. The solution needs to be used immediately once mixed.
