Electron Microscopy Sciences Resharpen Ultrasonic Knife

Electron Microscopy Sciences The diatome ultra sonic the oscillating diamond knife for room temperature ultramicrotomy produces ultrathin sections almost free of compression. A piezo actuator produces an oscillation of the knife at a desired frequency and amplitude, parallel with the cutting edge. A depression in the foot of the knife allows the oscillation parallel to the cutting edge. The depression is rigid in the north/south direction and guarantees stability in the cutting direction. The result is ultrathin sections almost free of compression. The sections become thinner at the same thickness setting since the volume of the section remains the same, the increased length leads to a decrease in thickness. Cutting range of 10-80 nm. Control unit has a frequency of 25-45 khz or automatic setting of the resonance. Variable amplitude with a voltage of 0-30v. - EMS
