General description

Silicone oil AR 20 is a polydimethylsiloxane with phenyl groups that is commonly used as a heat transfer or pressure transfer fluid.

Application

Silicone oil AR 20 has been used:
  • As a Segmenting fluid in polymerase chain reaction (PCR).[1]
  • In hollow fiber liquid-phase microextraction (LPME) procedure for extraction of hydrophobic drugs from human breast milk.[2]
  • As a fluid to demonstrate pores in droplet interface bilayers (DIBs).[3]

    Much worse than the old stuff!

    We use a lot of silicone oil in our lab, so bought this product in bulk. Each bottle has separated and has bits in the bottom, which interferes massively with our imaging- especially single molecule work. It's a good day when we find an aliquot of the old silicone oil (also purchased from Sigma), as it is much better quality and does not interfere with our imaging techniques.
