PBI's PCT systems are comprised of two major, interdependent components: the pressure cycling instrument and the consumable that contains and delivers the cycled pressure to the sample. The just patented PCT MicroPestle (the "PCT MP"

is PBI's most important and popular consumable. Its unique construction seals and protects the sample while flexing to transfer immense pressures. This facilitates homogenization and precise physical and chemical preparation of minute biological samples, such as needle biopsies, small suspensions of cells, and/or laser micro-dissected tissue sections. The PCT MP is made of inert fluoropolymer material, which enables stability throughout a very broad temperature range, as well as excellent resistance to aggressive chemicals. Its extremely low surface binding characteristics allow the PCT MP to preserve and maximize the availability of each sample's precious molecules, which could include important biomarkers to be discovered for disease diagnosis or for critical prognostic decisions on treatment selection and guidance.
