SPI Polywipers Lint Free Polyester Wipers, 4x4" (10.1x10.1cm), Pack of 600
SPI Polywipers™ are comprised of 100% continuous filament polyester fiber that is especially absorbent and clean. The unique knit construction, sometimes called a hydroentangled structure, has been developed to ensure integrity and cleaning performance. The product has been given a "laundering" treatment and is therefore extremely low in particle generation and soluble extractables. The laundering process is done in ultrafiltered water of 0.45 µm purity and dried in a HEPA filtered class 10 air stream. Each wipe is inspected and hermetically sealed in polybagged packages within a class 100 clean room that meets Federal Standard 209B.
