Harris Uni-Core Punch, 6.0mm Tip, Disposable, Stainless Steel, 4/Pk
Qiagen SKU: WB100040

Featuring a polished, case-hardened stainless steel cutting tip with a 6.0 mm inner diameter, this disposable Uni-Core Punch delivers fast, accurate manual coring of thin and soft substrates. The sharp steel cutting edge cores, retrieves, and controllably ejects uniform sample discs, supporting up to 500 punches per tip before disposal. The ergonomic plastic handle keeps the tool comfortable to grip, and its disposable design minimizes carryover between samples when the recommended cleaning procedure is followed. Manual punching is best suited to laboratories with low sample volumes punching roughly 1 to 5 samples per day.

Key Punch Characteristics

• Case-hardened stainless steel tip: a polished, hardened cutting edge produces precise, clean cuts and uniform sample discs.
• High punch life: each tip is rated for up to 500 punches before disposal.
• 6.0 mm coring diameter: sized for consistent disc removal from FTA cards, FTA Elute cards, and similar substrates.
• Controlled ejection: the design supports manual coring, retrieval, and controlled release of the punched sample.
• Contamination control: the disposable format limits cross-contamination and carryover between samples.

Key Construction Characteristics

• Handle material: lightweight plastic housing for a secure, comfortable grip.
• Compatibility: designed for use with Qiagen FTA Cards, FTA Elute Cards, and the EasiCollect device.
• Sterilization: the steel tip can be autoclaved at 250 degrees C for limited reuse.
• Pack: supplied 4 per pack.

This punch maintains sample integrity through clean, uniform cuts and controlled disc ejection, helping preserve nucleic acids and other analytes for downstream processing. Its disposable construction reduces the risk of carryover, while the durable, case-hardened tip provides reliable performance across hundreds of punches. The result is consistent, repeatable sampling for low-throughput laboratory workflows.
