常温超级钻石刀有两种角度(35º和45º)可以选择,钻石刀的长度1.5mm-4mm,使用此款钻石刀可以得到样品的适宜厚度范围在30-150nm。以下图片仅供参考。
1. 常温超级钻石刀45º
可以胜任一般常规的切片工作,在切片质量和使用寿命两方面都有很好的表现。对于极硬的材料和易碎的材料(例如陶瓷),推荐使用此款钻石刀。
2. 常温超级钻石刀35º
关于常温超级钻石刀的详细特性,可以参考J.JESIOR的相关著作,在其作品中详细描述了利用35º刀怎样得到更好的切片。
一直以来,大量的科学家认识到35º刀在Lowicryle(一般指K4M等包埋剂包埋的样品)、脱钙骨、牙齿等等材料的切片中发挥出色。
大量的实验证明,35º刀在软的工业样品(例如金属和聚酯类)的切片中发挥的与硬的易碎样品的切片一样出色,例如半导体材料(Si,GaAs等),超导氧化物,纳米晶体陶瓷等等材料。
