液体氮冰冻切片法国内虽已见报导,但方法不一,我科于1980年自行设计和制做液体氮持物器进行冰冻切片,经过四年来200余次的实践,效果满意,现介绍如下: 一、制做与材料将原国产石腊切片机的持物器部分全部去掉,换上液体氮持物器(见图1)。这个液体氮持物器由液体氮盒、冷凝器速接板套、冷凝器、液体氮漏斗,冷凝持物 Liquid nitrogen frozen sections France has reported, but the method is different, our department in 1980 to design and manufacture of liquid nitrogen holder for frozen sections, after four years of more than 200 times the practice, the effect is satisfactory, are described below: First, the system to do with the material The original domestic paraffin slicer part of the holster removed, replaced with liquid nitrogen holder (see Figure 1). The liquid nitrogen holder consists of a liquid nitrogen cartridge, a condenser quick-connect plate holder, a condenser, a liquid nitrogen funnel, a condensate holder
