Harris Uni-Core Punch, 2.0mm, Disposable, Autoclavable, 25/Pk
Qiagen SKU: WB100076

Featuring a polished, case-hardened steel cutting tip housed in an ergonomic plastic handle, this disposable Uni-Core Punch delivers clean, repeatable 2.0 mm cores from thin, soft substrates such as filter paper, gels, and dried blood on collection cards. Each tip provides up to 500 punches before disposal and can be autoclaved at 250 degrees C for limited re-use. Manual punching suits laboratories with low sample volumes processing one to five samples per day, and the disposable design minimizes cross-contamination and carryover between samples when a cleaning procedure is followed.
