Checkline 230 [230/50] Sample Cutter, Cuts 50 cm² Sample, 5mm Max Thickness. Sample Cutters cut out rapidly, accurately and safely circular specimens of fixed diameter. Virtually any type of material can be cut, including woven, non-woven and knitted textiles, carpet, film, foam, paper and board. Cut specimens are weighed to determine the weight per unit area. Alternatively, specimens are cut to a particular size, suitable for some other form of testing – a good example being a Martindale abrasion or pilling test. The cutters can handle a material thickness up to about 5mm. If you need more: Model 230/100(C) incorporates heavy-duty Stainless Steel Blades, resulting in a depth of cut of approximately 10mm. Operating Procedure: The material to be cut is placed between the Sample Cutter and the specially-designed Cutting Board. When the safety catch is released, light downward pressure on the handwheel brings the multiple blades into contact with the material. Specimens are cut by rotating the handwheel under a light, even pressure. The design, and precision manufacture of our instruments, ensures the specimens are perfectly circular and have smooth edges. A UKAS Calibration Certificate is available to validate the cutting accuracy. To maintain the cutting efficiency, the blades should be turned or changed when they become damaged or blunt, and the cutting board should be turned or changed when it becomes worn. For the best results use only the approved blades and boards. To determine weight per unit area, the cut specimen is transferred to a digital balance. Weigh a (100cm²) specimen in grammes, multiply the result by 100 and obtain instantly, grammes per square metre (g/m²) The Sartorius Talent Balance TE212 has a maximum weighing capacity of 210g, which caters for any material up to 2100g/m²
