Quantitative Circular Sampler

The quantitative circular sampler uses a rotating blade to cut standard circular specimens from the material surface, designed for measuring the mass per unit area of materials such as paper and films. During operation, the sampler is pressed onto a flat material and rotated to cut, obtaining a sample of fixed area for weighing and calculating the basis weight. It is suitable for laboratory testing in industries such as papermaking, plastics, and textiles.
Selection
When selecting a quantitative circular sampler, it is essential to confirm that the sampling area matches the standard specifications, with a common specification being 100 cm². The blade material should be tool steel to ensure durability, and the compression mechanism must provide uniform pressure. The sampling accuracy error should be checked to be less than ±0.35%, and the protective cover must have a safety locking function. Adjust the cutting depth according to the sample thickness, and consider using a sample tray for convenient collection.
