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*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
