Harris Uni-Core Manual Punch, 1.0 mm Tip, Stainless Steel, Disposable, 25/Pk
Qiagen SKU: WB100073

Featuring a polished, case-hardened stainless steel cutting tip set in a molded plastic handle, this disposable manual punch delivers precise, repeatable coring of thin and soft substrates such as filter paper, gels, and dried blood on sample cards. The 1.0 mm tip cores, retrieves, and controllably ejects a uniform sample disc in a single operation, supporting simultaneous extraction, collection, and storage. Each tip provides up to 500 punches before disposal, and the tool can be autoclaved at 250°C for limited re-use.

Key Punch Characteristics

• Polished, case-hardened stainless steel cutting tip delivers sharp, precise coring and clean disc ejection.
• 1.0 mm tip diameter suited to small-volume sample disc removal.
• Capable of up to 500 punches per tip before disposal.
• Sterilizable by autoclave at 250°C for limited re-use.
• Disposable design minimizes contamination and carryover between samples when a cleaning procedure is followed.

Key Construction Characteristics

• Stainless steel cutting tip housed in a molded plastic handle for comfortable manual operation.
• Designed for use with FTA Cards, FTA Elute Cards, and the EasiCollect device.
• Supplied 25 punches per pack.

This manual punch maintains uniform sample geometry and reliable disc ejection across repeated use, helping preserve sample integrity throughout downstream workflows. Manual punching is well suited to laboratories with low daily sample volumes, and the disposable format helps control cross-sample contamination when proper cleaning is observed.
