Product Introduction
This grammage sampler is specifically designed to punch standard 100 cm² circular specimens for paper and board grammage testing. It handles single or multiple paper sheets with a total thickness from 0.1 to 3.0 mm, and single-layer paperboard up to 0.6 mm thick. The cutter blade is made of special No.10 steel hardened by high-temperature quenching; its wave-shaped profile distributes cutting force evenly, resulting in smooth, burr-free edges and a notably extended blade life. The integrated pressing cover holds the sheet flat before the punch, eradicating movement and curl-induced errors. With a total weight of 15 kg and a rigid one-piece cast-iron body, the instrument sits firmly on any workbench and delivers repeatable results with a cutting accuracy of ±0.35 mm.

Key Features 
Industry Standard Compliant：Designed and manufactured per QB/T 1671-2017, ensuring standardized specimen preparation for paper and board physical property testing.
One-Piece Cast Iron Frame：The robust monolithic cast-iron construction eliminates structural flex, delivering unwavering dimensional stability over years of service.
Wave-Shaped Hardened Steel Blade：The blade is fabricated from special-grade No.10 steel, high-temperature quenched, with a wave profile that reduces cutting force and lasts significantly longer.
Exclusive Pressing-Cover Design：A built-in flattening cover clamps the specimen prior to punching, removing sheet curl and minimizing area errors at the source.
Standardized Specimen Area：Precisely cuts a 100 cm² round specimen—the standard area for grammage calculation—so results can be directly computed without conversion.
Versatile Thickness Range：Cuts single or multiple paper layers from 0.1 to 3.0 mm, and single-layer paperboard up to 0.6 mm, covering most routine test needs.
Tight Cutting Tolerance：Sampling accuracy within ±0.35 mm guarantees consistent specimen dimensions and highly reproducible grammage data.
Safe & Effortless Operation：A well-engineered lever mechanism coupled with the wave-edge blade makes punching smooth and low-effort, while built-in guards ensure operator safety.

FAQ 
Q: What materials can this sampler cut?
A: It is designed for cutting standard round specimens from various types of paper and paperboard for grammage testing.
Q: What is the specimen area?
A: The specimen area is 100 cm², which is the standard area prescribed for paper and board grammage determination.
Q: Is the device heavy? Does it need to be bolted down?
A: It weighs 15 kg with a solid cast-iron base, so it sits stably on the benchtop and requires no extra clamping or bolting.
Q: Can the blade be replaced if it becomes dull?
A: The blade is hardened for long life. Should replacement or sharpening ever be needed, please contact our after-sales service for support.
Q: How thick can the paperboard be?
A: For single-layer paperboard, the thickness should be less than 0.6 mm. Multiple layers of paper can be cut up to a combined thickness of 3.0 mm.
Q: How is cutting accuracy maintained?
A: The one-piece cast-iron frame and the integrated pressing-cover design hold the specimen flat and secure, keeping the cutting tolerance within ±0.35 mm for every sample.
