  • Best structure preservation

ultra sonic Oscillating Diamond Knife 35°

Patented piezo actuated ultra sonic oscillating diamond knife can produce compression free, ultra-thin sections with state of the art preservation of structure. Oscillation frequency can be set between 25 and 45 kHz and amplitude is adjustable by setting the voltage between 0 and 30 volts. Using these two adjustments, the oscillation produced parallel to the cutting edge can be varied to match the cutting characteristics of the material being sectioned. Section thicknesses range from 15 to 100nm. Blade width is 3.0mm. 110V power requirement.

ultra sonic maxi Diamond Knife 35°

The ultra sonic maxi diamond knife is similar to the ultra sonic but with a wider boat. It is designed specifically for biological serial sectioning. Oscillation frequency can be set between 25 and 45 kHz and amplitude is adjustable by setting the voltage between 0 and 30 volts. Using these two adjustments, the oscillation produced parallel to the cutting edge can be varied to match the cutting characteristics of the material being sectioned. Section thicknesses range from 15 to 100nm. 3.0 and 4.0mm blade widths. 110V power requirement.

The theoretical considerations and first results of this invention were presented in the Journal of Microscopy. Results with polymers using the oscillating knife were shown at the M&M 2002 meeting in Quebec.

The following materials were tested using the oscillating knife:

  • 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, etc.
