It provides civil engineering laboratories, geosynthetic manufacturers, and independent testing facilities with a consistent method of preparing specimens for mass per unit area and thickness evaluations. By establishing a uniform sample area before weighing, the cutter eliminates the variations associated with manually measuring, marking, and trimming each specimen.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eUnlike conventional textile sample cutters designed primarily for thin fabrics, the QualiGTX™ CSC offers a cutting depth of up to 15 mm. Standard circular fabric cutters typically accommodate materials only around 5 mm thick, restricting their use with heavier geosynthetics. The CSC can process thick needle-punched nonwovens, HDPE and LLDPE geomembrane sheets, and bonded geocomposites that often require manual cutting with conventional tools. Its 15 kg steel construction maintains die alignment throughout the cutting motion, producing clean, straight edges without the tapered profiles associated with uneven cutting.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe cutter operates entirely by hand and requires no electrical or pneumatic connections. The operator places the specimen on a suitable cutting surface, positions the die, and presses the lever handle downward to complete the cut. Measuring φ160 × 115 mm, its compact construction fits comfortably on laboratory workbenches, can be transported to field inspection locations, and requires minimal storage space between operations.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eLever-Operated Circular Geotextile Sample Cutter – QualiGTX™ CSC Applications\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe QualiGTX™ CSC is suitable for laboratory and production environments where physical property evaluations require consistently sized circular specimens.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cspan\u003eGeotextile Mass per Unit Area Testing:\u003c\/span\u003e\u003cspan\u003e Produces standardized 100 cm² specimens for determining fabric mass per unit area.

As the cutting edge penetrates the specimen, the resulting shear stress eventually exceeds the material's shear strength, allowing the blade to pass through the fabric. Because the cutting edge engages the entire circumference simultaneously, the material is less likely to shift or stretch away from the blade during operation.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePressure applied through the lever handle passes through the rigid steel assembly and is distributed around the circular cutting edge. This uniform force produces a controlled separation with a clean perimeter, avoiding the gradual tearing and uneven edges that can occur when specimens are cut with scissors. A resilient cutting mat or similar surface beneath the material allows the blade to extend slightly beyond the specimen's final fiber layer without striking a hard workbench, helping protect the cutting edge from damage.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe principal advantage of this method is its fixed specimen geometry. A circular area of 100 cm² corresponds to a diameter of approximately 113 mm. Since this dimension is established by the cutter's machined die, rather than determined through manual measurement, each specimen retains the same nominal area regardless of the operator. This simplifies mass per unit area calculations: when a 100 cm² specimen is weighed in grams, multiplying its mass by 100 gives the result in grams per square meter. No additional area adjustment is necessary, reducing calculation steps and the possibility of arithmetic errors.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMaintaining cutting accuracy is particularly important because specimen area changes with the square of its diameter. For a circle measuring approximately 113 mm in diameter, a diameter deviation of just 1 mm can change the specimen area by around 1.8%. The same percentage variation carries directly into the calculated mass per unit area. This becomes especially problematic when manually cutting thick or compressible materials against a marked template, where dimensional deviations can easily exceed 1 mm. The precision-machined circular die eliminates this source of variation, providing the repeatable specimen dimensions required for reliable geosynthetic laboratory testing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003e\n    Lever-Operated Circular Geotextile Sample Cutter - QualiGTX™ CSC Technical Specifications\n\u003c\/h2\u003e\n\u003ctable class=\"table\" style=\"width:100%;\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth\u003e\n                Parameter\n            \u003c\/th\u003e\n            \u003cth\u003e\n                Specification\n            \u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\n                Specimen Area\n            \u003c\/td\u003e\n            \u003ctd\u003e\n                100 cm²\n            \u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\n                Nominal Specimen Diameter\n            \u003c\/td\u003e\n            \u003ctd\u003e\n                ≈113 mm (geometric equivalent of 100 cm²)\n            \u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\n                Maximum Cutting Thickness\n            \u003c\/td\u003e\n            \u003ctd\u003e\n                15 mm\n            \u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\n                Overall Dimensions\n            \u003c\/td\u003e\n            \u003ctd\u003e\n                φ160 × 115 mm\n            \u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\n                Net Weight\n            \u003c\/td\u003e\n            \u003ctd\u003e\n                15 kg\n            \u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\n                Operation\n            \u003c\/td\u003e\n            \u003ctd\u003e\n                Manual, lever-operated\n            \u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\n                Power Requirement\n            \u003c\/td\u003e\n            \u003ctd\u003e\n                None\n            \u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\n                Suitable Materials\n            \u003c\/td\u003e\n            \u003ctd\u003e\n                Geotextiles, geomembranes, geocomposites, woven, knitted, blended, and synthetic-fiber fabrics\n            \u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Qualitest USA LC","offers":[{"title":"Default Title","offer_id":53601830240567,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/lever-operated-circular-geotexti.webp?v=1794465131","url":"https:\/\/qualitest.us\/products\/lever-operated-circular-geotextile-sample-cutter","provider":"Qualitest USA LC","version":"1.0","type":"link"}
