Recirculating etch bath filter

The Ulti-Etch filter provides high flow rates and rapid bath turnover in new-generation etch baths, while ensuring high-efficiency particulate removal and low extractable levels. It uses the crescent-shaped Ultipleat filter design, which combines high voids volume with increased filter area. Constructed from a hydrophilic PVDF medium, Ulti-Etch has a 0.1-?m removal rating in recirculation mode. PVDF, a naturally hydrophobic medium, is hydrophilized by chemically surface modifying the medium surface, minimizing potential extractables.
