Etching creates a bondable fluoropolymer tubing
This company now offers onsite etching to create a bondable surface on PTFE, FEP and PFA (photo). Because the lubricity of the fluoropolymer tube surface hampers its bondability, etching is required to alter the tube surface in order to allow adhesion. Etching services are available on the inner or outer diameter, or both, of this company's products. In the process, etching chemicals are used to modify the surface of the fluoropolymer materials in order to enhance the bondability. The chemical reaction between the etch and the fluorine in the tubing eliminates the smoothness of the tube, stripping the fluorine and leaving the tube surface rough. Once the surface lubricity has been altered, the tubing can be bonded to almost any surface. Etching does alter the color of the tube and ranges from light to dark brown. The color, however, does not determine the strength of the etch. Unlike natural fluoropolymer tubing, etched tubing must be stored in black plastic bags to keep out light and retain the effects of chemical alteration. Offered in sizes from 0.004-4-in. dia., etched tubing is a custom, made-to-order product. - Parker-Texloc, div. of Parflex, Fort Worth, Tex.

Achieve various levels of water quality with this filter
The Automated Disc Filter (ADF, photo) is an automatic, self-cleaning, plastic disc filter. In this system, water enters through an inlet pipe at the bottom of the filter housing, where "fin plate" blades force the water to enter the chamber with a vortex effect. This effect causes dirt particles to collect on the upper wall of the filter chamber, where they remain until the next flushing cycle. As the water flows from the outside of the disc stack to the inside, grooves on the discs catch the suspended material. Clean, filtered water flows of the the filter from the center outlet. The system is cleaned by reverse flow, which can be triggered by pressure differential, time, or both. - Amiad Filtration Systems, Oxnard, Calif.
