Diatome ultra knives and their applications

  • Highest quality diamonds and optimal crystal orientation guarantee perfect ultrathin sections and a durable cutting edge
  • Section pick-up is facilitated as the boat is horizontal allowing the water to completely fill the boat all the way round
  • A hydrophilic surface makes it easy to wet the cutting edge, even with low water level
