目前,透射电镜标本样品制备所用的包埋盒基本上用有机玻璃制成的。但在长期使用后发现不少缺点,如在样品制备过程中有疏忽或胶囊有不易观察到的小裂痕,可使包埋剂外溢,造成单个样品废弃,有时还会影响周围样品,同时也使包埋样品盒使用率降低,给电镜生物样品制备带来不便。 At present, the cassettes used in the preparation of TEM specimens are basically made of plexiglass. However, many shortcomings have been found after long-term use, such as inadvertent sample preparation or small cracks in the capsule that can be observed. This can cause the overflow of the embedding agent, resulting in the abandonment of a single sample, sometimes affecting the surrounding sample as well as Buried sample box to reduce the use of biological sample preparation to bring the inconvenience.
