Constructed entirely from premium natural polypropylene, this plate offers exceptional heat stability and broad chemical resistance, making it suitable for aggressive organic synthesis and combinatorial chemistry workflows. Each of the 10 mL wells is equipped with a 25 to 30 µm melt-blown polypropylene (MBPP) depth filter, which excels at clarifying large particulate loads without premature clogging. To ensure absolute sample integrity during downstream collection, the plate features Whatman's patented long drip director geometry. This extends the fluid path securely into the receiving plate, completely preventing aerosolization and well-to-well cross-contamination during vacuum filtration.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMelt Blown Polypropylene (MBPP) Membrane:\u003c\/b\u003e The 25–30 µm depth filter matrix provides an excellent balance of high flow rates and high dirt-holding capacity, ideal for processing viscous matrices or high-solids cellular debris.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePatented Long Drip Director:\u003c\/b\u003e The specialized nozzles extend significantly below the filter plane, ensuring that discrete sample streams fall straight into the collection plate without splashing or creeping along the plate bottom.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eChemical and Heat Resistance:\u003c\/b\u003e The natural polypropylene housing is highly inert, preventing the leaching of plasticizers and allowing the plate to withstand harsh organic solvents and elevated incubation temperatures.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHigh-Volume 10 mL Wells:\u003c\/b\u003e The massive 10 mL per-well capacity bridges the gap between standard 96-well microplates and individual solid-phase extraction (SPE) columns, significantly increasing high-throughput processing efficiency.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e 7700-9904\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePlate Format:\u003c\/b\u003e 24-Well\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaximum Volume:\u003c\/b\u003e 10 mL per well\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eFilter Media:\u003c\/b\u003e 25–30 µm Melt Blown Polypropylene (MBPP)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePlate Material:\u003c\/b\u003e Natural Polypropylene\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eDrainage Design:\u003c\/b\u003e Long Drip Director\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSolid Phase Extraction (SPE):\u003c\/b\u003e The industry standard for large-volume, high-throughput SPE, effectively replacing the need for time-consuming manual extraction using individual cartridges.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCombinatorial Chemistry:\u003c\/b\u003e Built to survive the aggressive reagents and harsh washing steps required during the automated parallel synthesis of chemical libraries.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eZero Cross Talk:\u003c\/b\u003e The long drip directors provide researchers with peace of mind that highly sensitive target molecules will not cross-contaminate adjacent wells during vacuum manifold evacuation.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eAutomated Liquid Handling:\u003c\/b\u003e The plate footprint adheres to standard automation dimensions, making it easily adaptable to robotic liquid handlers and vacuum stations.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\u003cp style=\"margin: 0; font-size: 0.8em;\"\u003e\u003ci\u003eAll product names, logos, and brands are property of their respective owners.\u003c\/i\u003e\u003c\/p\u003e","brand":"Whatman","offers":[{"title":"Default Title","offer_id":44516806263036,"sku":"5012","price":52.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/whatman-unifilter-microplate-24-well-10-ml-pp-long-drip-director-5-plates-petri-dishesculture-plates-whatman-295863.jpg?v=1754967774","url":"https:\/\/lifesciencestrading.com\/products\/whatman-unifilter-microplate-24-well-10-ml-pp-long-drip-director","provider":"Life Sciences Trading","version":"1.0","type":"link"}
