目前大部分冷冻切片机都带有防卷板,只要调整好,能保证冷冻切片的平整,并使切片过程更为便利、快速。但用过一段时间后防卷板的玻璃刃口就会受损产生毛糙,切片表面就会被刮伤而产生刀痕。这时就必需更换防卷板。但由于防卷板价格昂贵(如Leica1900冷冻切片机防卷板要1 000多元),而且等货时间长,故大部分单位就只好凑合使用或干脆放弃不用,直接用手来接片防止片子卷曲,很麻烦,也影响切片质量。本法可使旧防卷板完好如新,方法也极其简 At present, most of the frozen microtome are equipped with anti-coil plate, as long as the adjustment is good, to ensure the smooth formation of frozen sections, and make the slicing process more convenient and fast. However, after a period of time, the glass edge of the anti-roll plate will be damaged and rough, resulting in scratches on the sliced ​​surface. At this time must replace the anti-coil plate. However, due to the high price of anti-coil (such as Leica1900 frozen slicer anti-coil to more than 1,000 yuan), and waiting for a long time, so most of the units had no alternative but to improvise or simply do not have to use the direct hand tab to prevent the film curl , Very troublesome, also affect slice quality. This law can make the old anti-Coil intact, the method is also extremely simple
