Rather than sealing only the cut perimeter, the Choice Edge incorporates a no-run interlock border on all four sides, which virtually eliminates fiber shedding even under aggressive wiping pressure. Laundered in an ISO Class 4 cleanroom, the CHKE09.14 is rated for ISO Class 3 through ISO Class 5 environments and is particularly well-suited for applications where wiper integrity during use is as important as initial cleanliness — such as wiping optical surfaces, precision instruments, or critical process equipment where a fraying edge would be unacceptable.\u003c\/p\u003e\n\n\u003cp\u003eMTE Solutions stocks the CHKE09.14 in cases of 1,400 sheets (100 wipes per pack, 14 packs per case). The 9\" x 9\" format covers the standard cleanroom bench footprint, and the 4-side border construction makes this wiper a strong choice for facilities that have experienced edge-shedding issues with standard sealed-edge wipers or that require the highest level of edge integrity for their process validation documentation.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eCHKE09.14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBerkshire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eChoice Edge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e9 in x 9 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e100% Polyester (Continuous-Filament Knitted)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEdge Treatment\u003c\/td\u003e\n\u003ctd\u003e4-Side Border Sealed Edge (No-Run Interlock)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLaundering\u003c\/td\u003e\n\u003ctd\u003eLaundered in ISO Class 4 Cleanroom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eISO Classification\u003c\/td\u003e\n\u003ctd\u003eISO Class 3 – ISO Class 5 (Class 1 – Class 100)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack Quantity\u003c\/td\u003e\n\u003ctd\u003e100 wipes per pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Quantity\u003c\/td\u003e\n\u003ctd\u003e1,400 sheets (14 packs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWipe Type\u003c\/td\u003e\n\u003ctd\u003eDry\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eOptical surfaces, precision instruments, critical process equipment, ISO Class 3–5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat makes the Choice Edge different from the Choice 700?\u003c\/strong\u003e\u003cbr\u003eBoth are 100% polyester knitted wipers laundered in an ISO Class 4 cleanroom, but the Choice Edge features a 4-side border sealed edge with a no-run interlock construction on all four sides. The Choice 700 uses a standard ultrasonically sealed perimeter edge. The Choice Edge’s 4-side border virtually eliminates fiber shedding even under aggressive wiping pressure, making it the preferred choice when edge integrity is critical.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is a “4-side border sealed edge”?\u003c\/strong\u003e\u003cbr\u003eA 4-side border sealed edge means all four sides of the wiper — not just the cut edges — incorporate a no-run interlock border that prevents fiber unraveling.
