Circular Sample Cutter

Circular Sample Cutters

Fixed 100 cm² Specimens for ASTM D5261 and ISO 9864 Mass per Unit Area Testing

Circular sample cutters prepare round specimens of a precisely defined area from fabric, geotextiles, and sheet materials. By producing a consistent 100 cm² sample, they allow laboratories to determine mass per unit area through weighing alone, eliminating the need to measure specimen dimensions separately. These instruments are essential for geosynthetic manufacturers, testing laboratories, and field inspection teams conducting mass per unit area evaluations in accordance with ASTM D5261 and ISO 9864. Consistent cutting area is particularly important because it directly affects the accuracy of the calculated results.

The QualiGTX™ Circular Sample Cutter range accommodates materials up to 15 mm thick, making it suitable for heavy needle-punched nonwovens, HDPE and LLDPE geomembranes, and bonded geocomposites. Its cutting capacity extends beyond the limits of conventional textile cutters designed for thinner materials. Two configurations are available to accommodate laboratory testing and on-site sampling requirements.

Applications

Circular sample cutters provide the specimen preparation needed for a wide range of geosynthetic and technical textile testing procedures. They are particularly useful wherever accurate mass per unit area measurements depend on specimens with consistent dimensions.

• Geotextile Mass per Unit Area Testing: Produces standardized 100 cm² specimens for weighing under ASTM D5261 and ISO 9864, allowing results to be expressed in grams per square meter.

• Incoming Roll Goods Inspection: Enables quality control teams to check the actual material weight against declared specifications before accepting deliveries for project use.

• Geomembrane and Liner Quality Control: Prepares circular samples from thick polymer sheets for subsequent thickness, density, and visual examination.

• Geocomposite and Drainage Product Sampling: Cuts through bonded, multi-layer materials while maintaining the integrity of the individual layers along the specimen edge.

• Technical Textile Manufacturing: Prepares samples from woven, knitted, blended, and synthetic-fiber materials for grammage determination and construction analysis.

• Site Conformance and Dispute Documentation: Provides consistently sized witness specimens for quality assessments and investigations involving disputed material performance.

Circular Sample Cutter Range

Both QualiGTX™ models use the same cutting geometry and accommodate materials up to 15 mm thick. Their main difference is the operating arrangement and portability, allowing users to select a cutter according to their sampling environment.

• Lever-Operated Circular Geotextile Sample Cutter (QualiGTX™ CSC): Designed for stationary laboratory use, this bench-mounted configuration uses its own weight to maintain stable, square contact with the specimen during cutting. Its substantial mass helps keep the cutter steady throughout operation, making it suitable for laboratories processing regular specimen volumes at a dedicated workstation.

• Handheld Circular Geotextile Sample Cutter (QualiGTX™ CSC H): Weighing just 1.5 kg, this portable model can be carried directly to the material being inspected. It is particularly suitable for field inspectors, incoming goods inspection teams, and production personnel who need to collect specimens at different locations.

How to Choose the Right Circular Sample Cutter

Selecting the appropriate model depends primarily on the sampling location, frequency of use, and material handling requirements.

• For Dedicated Laboratory Workstations: The CSC is the preferred option for fixed testing stations. Its heavier construction provides stability during cutting and reduces the manual effort required for each operation.

• For On-Site Inspections and Delivery Verification: The CSC H offers greater mobility, allowing inspectors to transport the cutter in a sampling kit and collect specimens directly from delivered rolls.

• For Sampling Across the Full Roll Width: The CSC H is a practical choice when specimens must be collected from multiple positions across a roll. Its lightweight construction makes repeated sampling easier to manage.

• For Thick Nonwovens, Geomembranes, and Geocomposites: Both models provide the same cutting capability, accommodating material thicknesses up to 15 mm.

• For High-Volume Daily Testing at One Location: The CSC is better suited to repeated cutting operations at a dedicated workstation, where its stable construction helps reduce operator fatigue.
