Electron Microscopy Sciences EMS-002 Rapid Immersion Freezer (Plunge Freezer)

Electron Microscopy Sciences Rapid Immersion Freezer

 

The EMS-002 Rapid Immersion Freezer is designed for special applications to rapidly freeze biological samples to preserve their native structures for microscopic examination. Ultrarapid freezing of a sample preserves the ultrastructure and antigenicity of the sample better than conventional room temperature chemical fixation.

  • Coolant used is liquid nitrogen cooled propane
  • Special design keeps the propane at the correct temperature for an extended freezing experiment
  • Automated “Drop Anvil” for fast, consistent plunge freezing
  • Freeze liquid samples on electron microscopy grids
  • Freeze tissue pieces on special freezing pins

Leica EM AFS2/EM FSP Automatic Freeze Substitution System

Leica EM AFS2/EM FSP Automatic Freeze Substitution System

 

The Leica EM AFS2 Automatic Freeze Substitution System performs freeze substitution and progressive lowering of temperature (PLT) techniques along with low temperature embedding and polymerization of resins.

  • Flat Embedding and Microtube Embedding System with Freeze Substitution Processor (FSP) 
  • An automated reagent handling system
  • LED chamber illumination
  • Stereomicroscope
