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]

This paper evaluates the compatibility of segmenting fluids for two phase flow applications in biomedical microdevices. The evaluated fluids are chosen due to the variations in fluid properties and cost, while also reflecting their use in the recent literature. These

In some polymers, in addition to the usual structural alpha relaxation, a slower alpha' relaxation is observed with a non-Arrhenius temperature dependence. In order to understand better the molecular origin of this alpha' relaxation in poly(methylphenylsiloxane) (PMPS) we have studied
