Harris Uni-Core Punch, 2.0mm, Stainless Steel Tip, Autoclavable, 4/Pk
Qiagen SKU: WB100029

Featuring a polished, case-hardened stainless steel cutting tip, this disposable 2.0mm coring punch delivers clean manual sample extraction from thin and soft substrates. The tip is housed in an ergonomic plastic handle for comfortable, controlled use, and each tip provides up to 500 punches before disposal. Designed for use with FTA Cards, FTA Elute Cards, and the EasiCollect device, it cuts, retrieves, and ejects cored sample discs in a single operation while minimizing carryover between samples when the recommended cleaning procedure is followed.

Key Punch Tip Characteristics

• Polished, case-hardened stainless steel cutting tip provides accurate, clean cuts from materials such as FTA, 903, and DMPK cards.
• 2.0mm tip diameter suited to sampling FTA cards containing buccal cells, plasmids, plant, and other samples with lower DNA content.
• Delivers up to 500 punches per tip before disposal.
• Suited to thin and soft substrates including filter paper, dried blood spots (DBS) on cards, and gels.
• Can be sterilized by autoclaving at 250 degrees C for limited reuse.

Key Construction Characteristics

• Stainless steel cutting tip mounted in a disposable plastic handle for contamination control.
• Manual coring, retrieval, and controlled ejection of the cored sample disc.
• Disposable design minimizes contamination and carryover between samples.
• Supplied 4 punches per pack.

This punch maintains sample integrity by enabling clean cuts and controlled ejection, reducing the risk of cross-contamination between cards. Its disposable, low-cost format makes it well suited to laboratories with low sample volumes that perform manual punching. Pairing the punch with a companion cutting mat helps ensure clean cuts and extends the working life of the cutting tip.
