Purpose Pharmallne N GP hose is the 'General Purpose' grade, for use in all applications where fluids or gases being conveyed which do not generate a risk of static charge delvelopment.
Materials & Specifications
GP Grade has a virgin PTFE liner, manufactured from hose grade PTFE which conforms to the requirements of:
FDA 21 CFR 177.1550
Both the PTFE liner tube and the platinum cured silicone rubber covers have been tested and conform to the requirements of SU Class VI. Additionally, the PTFE liner tube meets the requirements of USP Class VI at 121°C (250°F)
Pharmaline N AS Grade is an essential requirement in applications where there is the risk of an electrostatic charge build-up on the inside surface of the PTFE tube which may then discharge through the tube wall. Media passing through which create such a risk are fluids which have a Conductance of less than 10-8 S/m (Siemens per Meter), or 10+4 pS/m such as fuels, solvent, freons, some WFI (ultra-pure “Water for injection”) and non-polar organics which are being transferred at a medium to high flow velocity.
All twin or multi-phase media, any non-mixing media, such as powder in air, or water droplets in steam, in gases or in oil, ...
