POROUS PTFE RODS, TUBES & SHEETS
PTFE Porous Rods, Tubes & Sheets are excellent for use in extreme heat up to +500° F (260° C) and resistant to a low end temperature of -328° (-200° C). PTFE is used in applications where other plastics break down due to their inability to be resistant to chemicals and heat. It is said that PTFE exhibits a combination of mechanical, electrical, chemical temperature and friction resistant properties unmatched by any other substrate. It is a non-reactive, high molecular weight fluoropolymer compound used in aerospace, pharmaceutical, chemical and petrochemical fields.
BLUNT TIP PIPETTING NEEDLES
Our 2″, 4″ & 6″ long laboratory blunt tip pipetting needles are available in gauges 5 through 30. Needle lengths of 12″ long are available in 8 through 27 gauge. All needles are made of 304 stainless steel and fitted with American standard short female luer hubs of nickel-plated brass. The short hub reduces the dead volume inherent in all American standard luer hubs. Needles are supplied with a 90-degree blunt tip.
FEP (Fluorinated Ethylene Propylene) holds its shape under stress and high temperatures better than PTFE. FEP has a temperature range of -320º F. to +400º F, is FDA compliant, and meets UL 94V0 for flammability. Ideal applications for this fluoropolymer are 3D printers, tank and pump linings, UV applications, and gasketing and mold release. These materials offer excellent electrical insulation, chemical resistance, weatherability and low permeability. Manufactured in the United States. When using this FEP Film with 3D printers we strongly recommend using at least 5 MIL or 10 MIL thick film.
POROUS RODS & TUBES
Our Porous Rods & Tubes are available in hydrophobic and hydrophilic formulations to accommodate your needs.
Porous Rods are used in wicking and venting applications. Through capillary action, our porous plastic wicks are capable of drawing aqueous and non-aqueous fluids out of a reservoir for dispersion through direct absorption or evaporation.
Our Porous Tubes are made from UHMW (ultra high molecular weight) polyethylene, PE co-polymers, or polypropylene with an average pore size from 5-200 microns. They are strong at various wall thicknesses with the ability to withstand high levels of pressure. The material is resistant to many chemicals and a wide range of temperatures.
