打孔器
组织或者截取微细部位样品的得力帮手。
· 法医学应用-打孔取材，从现场保存带回，对于一些源材料，诸如纸张、胶片、布料、树叶、漆片、薄膜等可以直接取出蕞优芯样
· 电生理学的应用-在快速分裂前的离散区域取样进行批记录
· 药理学的应用-可以在大脑不同区域取样以便检测其神经传导和代谢产物变化（对**试剂的反应）
· 解剖学的应用以及电子显微镜方面的应用也很大量
一、打孔器（哈里斯）
多用途，适合较软目标取样的的工具（挖取凝胶就可以用此产品啦），由塑料PP制造，器体中空，内置一带由锋利周缘的打孔头，还有样品从打孔头内打出的弹射装置。此产品单独无菌包装，可以一次性使用，也可以用乙醇浸泡打孔头，在250华氏温度下煮30分钟，加压14磅/平方英寸再接着使用。以下图片仅供参考，该产品外观在不断改进中。

使用方法：
1. For most forensic samples, position source of materials (i.e. blood cards, paint chips, paper, leaves, gels, etc.) on the self-healing cutting mat. Remove the protective cover cap from the punch. Firmly grip the punch. The tip is then positioned at a right angle above the target area – DO NOT DEPRESS THE PLUNGER. The tip is pushed downward into the source material until it makes contact with the cutting mat. Lift the Harris Micro-Punch™ away from the source material with the cored sample stored in the cutting tip.
2. For most biology samples – Typically tissue to be punched is first sliced into 1-2mm thick sections. The section to be punched is then placed on a saline-soaked filter paper disc on an ice-cold dissection plate ,Then follow the above procedure.
样品的保存与弹出：
After coring, the sample is temporarily stored in the hollow cutting tip ready for the preferred ejection. The Harris MicroPunch™ can be rested on its side without loss of sample from the hollow tip. To eject sample, position tip over target area and depress plunger.
清洗：
Clean the tip between each sample extraction by coring blank filter paper, rinsing with ethanol or spraying with compre
