Miltex® Sterile Disposable Biopsy Punch with Plunger
1.5mm Diameter | Box of 25 | Colour-Coded | Sterile, Single-Use

The Miltex® Sterile Disposable Biopsy Punch with Plunger (33-31A-P/25) combines the razor-sharp cutting performance of a traditional stainless steel punch with a built-in plunger mechanism for controlled, hands-free specimen ejection. The seamless, stainless steel cutting edge produces clean, uniform tissue cores without the torn or pulled margins that can compromise histopathology results.

The integrated plunger allows clinicians to eject the tissue core directly into a specimen container with a simple push, reducing the need to manipulate the sample with forceps and helping to preserve tissue integrity for pathology review. At 1.5mm in diameter, this punch suits a range of routine dermatologic biopsy procedures, offering a slightly larger core than the 1mm size while remaining well-suited to smaller lesions and sensitive sites.

The punch is colour-coded by size for quick identification at the point of care, with sizing clearly marked on each unit to reduce the risk of selecting the wrong instrument mid-procedure. Supplied sterile with a 5-year shelf life, each punch is intended for single-use only, eliminating reprocessing costs and reducing the risk of cross-contamination associated with reusable punches.

This item is part of the Integra Miltex Dermatology Catalogue and is available in a range of diameters to suit different biopsy requirements.
