Harris Uni-Core Punch, 1.2 mm, 25/Pk
Qiagen SKU: WB100074

Featuring a polished, case-hardened steel cutting tip housed in an ergonomic plastic handle, this Uni-Core Punch delivers precise 1.2 mm sample coring for dried blood spots, FTA cards, gels, and thin or soft substrates. The disposable design supports clean, repeatable sampling, with each tip capable of producing up to 500 punches before disposal. Manual punching suits laboratories with low daily sample volumes, and the unit can be autoclaved at 250 degrees C for limited re-use.
