Harris Cutting Mat 6 in. x 8 in.

Qiagen Whatman Harris Micro-Punch Cutting Mat – 6 in. x 8 in., Self-Healing Inert Matrix, Core Sample Punch Foundation, Contamination Control (MPN: WB100020)

The Qiagen WB100020 (originally developed under the Whatman / Cytiva brand as part of the Harris accessory line) is an instrument-grade, high-durability laboratory cutting mat precision-engineered for manual sample harvesting workflows. Measuring exactly 6 inches by 8 inches (15.2 cm x 20.3 cm) with a 1.5 mm structural thickness, this specialized mat provides a protective foundation for punching core discs out of dried biological matrix samples, tissue samples, and generic filter substrates. Fabricated from an advanced, inert polymer matrix, its self-healing surface yields slightly under mechanical force to absorb the downward thrust of specialized cutting tips. This pairing ensures complete, fray-free sample release while extending the operational lifespan and cutting-edge sharpness of manual sampling punches.

Technical Performance and Design

• Resilient Self-Healing Polymer Layer: Engineered with a specialized high-density polymer structure that cushions deep puncture stresses. The material automatically pulls back together after structural displacement, preventing permanent slicing grooves that trap debris or warp subsequent sample card cuts.

• Punch Edge Conservation Architecture: Acts as a sacrificial, energy-absorbing backing sheet. By providing a semi-yielding floor instead of a rigid metal or glass work surface, it preserves the delicate circular cutting edge of micro-punches from flattening, micro-chipping, or dulling prematurely.

• Alcohol-Washable Contamination Barrier: The inert, non-porous chemical surface matrix is completely resistant to routine laboratory cleanroom sanitizers, including 70% to 100% Isopropyl Alcohol (IPA) and Ethanol. This allows technicians to clean the work surface between extraction runs to prevent cross-contamination.

• Stabilized Non-Slip Geometric Layout: Molded with a low-profile, high-friction backing that grips onto standard laminar flow hood stainless steel decks and polymer laboratory benchtops, eliminating shifts or sliding errors during critical hand-punches.

Key Benefits and Applications

• FTA and FTA Elute Card Processing: The premier industry-standard foundation used to manually harvest clean sample disks from dried blood spots, saliva matrices, and plant tissues archived on genomic collection cards.

• Forensic Evidence Sampling: Extensively deployed across police crime labs, genotyping networks, and molecular biology repositories for preparing high-purity DNA and RNA extraction templates ahead of PCR amplification.

• Fray-Free Sample Disk Recovery: Ensures manual punches slice cleanly and completely through fibrous collection papers, preventing partial tears that alter volumetric sample sizes and compromise downstream target analyte quantification.

• Low-Extractable Integrity Shield: Free of chemical plasticizers, lubricants, or heavy dyes that could leach into biological specimens during compression, ensuring reliable compatibility with sensitive liquid chromatography-mass spectrometry (LC-MS) diagnostic protocols.
