ultra sonic

• Thinner sections
• No compression
• Best structure preservation

The patented ultra sonic knife allows the cutting of ultrathin sections free of compression (D. Studer et al., Journal of Microscopy, Vol. 197, pp. 94 – 100, 2000).

With correct setting of frequency and amplitude the sections become as long as the height of the sample.

Best results are not only achieved with biological samples, but also with polymers (J. S. Vastenhout et al., Microscopy and Microanalysis 8, 2001. J. S. Vastenhout et al., Microscopy Today, pp. 20 – 21, 2006).

We have tested the ultra sonic knife with the following samples:

• Biological samples in Epon, Araldite, EM Bed, etc.
• Biological samples in acrylic resins (Lowicryl, LR White).
• Rigid polymers such as PS, PMMA, ABS, HIPS, modified PP, blends of various kind
