General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Glycerol provides a high boiling point, low flammability, and polarity. Glycerol is non-toxic, biodegradable, and comes from a renewable feedstock, thus it aligns with "Safer Solvents and Auxiliaries", "Use of Renewable Feedstocks", and "Design for Degradation". Click here for more information.

Application

Glycerol can be used in a broad range of applications:
  • Sample preparation and gel formation for polyacrylamide gel electrophoresis
  • It is used to aid in casting gradient gels and as a protein stabilizer and storage buffer component
  • As a solvent in organic synthesis, such as Huisgen cycloaddition of azides
  • In pharmaceutical and personal care industries as a humectant and for improved smoothness


Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel′s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component.
