RMC LN Ultra cryosectioning system

RMC LN Ultra is a cryosectioning system option for RMC PowerTomes. LN Ultra will produce high quality, ultra-thin cryosections for demanding techniques such as CEMOVIS, cryo-immuno-labelling by the Tokuyasu method, soft polymers and other materials such as gels.

The high thermal stability of the specimen arm and cast aluminium chamber easily produces sections of exceptional quality. Now with new LED illumination to increase operator comfort and performance.

  • Chamber mounts and dismounts easily and converts any RMC PowerTome for low temperature sectioning
  • High precision temperature control is possible across a range from -180°C to +35°C
  • User defined temperatures for different techniques stored in four memory channels
  • Thermally efficient cryogenic design ensures low LN2 consumption, negating the need for large bulky dewars
  • Externally heated walls eliminate the risk of condensation in the working chamber
  • Ergonomically designed workstation for easier section manipulation for left and right handed users

To configure a working LN Ultra you will require the following:

  1. LN Ultra cryosectioning system (CRY-1001)
  2. Unless retrofitting to an existing RMC PowerTome you will need: PowerTome (PT-XL, PT-PCZ or PT-3D) with antivibration table (GEN-1021) and if required, compressor (GEN-1022)
  3. DiATOME knives : cryo immuno 3.0mm (DCIMM3530) and trim 90 (DTB90)
  4. Static line ioniser (GEN-1030)

Please contact Labtech  for further information on accessories and options.
