First, sample air is pumped through mixed cellulose ester membranes to extract airborne fibers. The asbestos concentration is analyzed with phase contrast microscopy, and asbestos fibers are analyzed in line with set rules that determine if a space is within airborne exposure limits.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"DSCBalances","offers":[{"title":"7141-047","offer_id":39523906977942,"sku":"7141-047","price":296.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0489\/6990\/8374\/files\/digi-26507-original-png.jpg?v=1793121474","url":"https:\/\/www.dscbalances.com\/products\/whatman-cellulose-ester-membrane-filters-membraclear","provider":"DSCBalances","version":"1.0","type":"link"}
