The GESTER GT-KC01-1 Veslic Rub Fastness Tester is a benchtop laboratory instrument designed to measure the color fastness and surface wear resistance of leather, footwear uppers, synthetic materials, and coated fabrics. It evaluates finish damage, color transfer, and surface breakdown under regulated cyclic rubbing with standard wool felt in both dry and wet conditions. Compliant with ISO 11640, DIN 4843, and EN ISO 20344, the GT-KC01-1 provides precise, reproducible quality control data for leather tanneries, footwear manufacturers, and automotive interior laboratories.

The GESTER GT-KC01-2 IULTCS & Veslic Tester is a high-efficiency laboratory testing instrument engineered to assess the rubbing color fastness and surface durability of natural leather, synthetic leather, plastics, and coated textiles. Featuring two independent testing stations, the iultcs veslic rub fastness tester allows laboratory technicians to perform simultaneous dry and wet rubbing fastness tests or run parallel sample evaluations, effectively doubling testing throughput. Fully compliant with ISO 11640, SATRA PM 173, and EN ISO 20344, the instrument evaluates finish adhesion, color bleeding, and surface degradation under controlled cyclic pressure using standard white wool felt pads. It is widely used in commercial testing laboratories, tannery R&D centers, footwear manufacturing facilities, and automotive trim production lines.
