Freeze Substitution and Low Temperature Embedding System for Light and Electron Microscopy Leica EM AFS2

The Leica EM AFS2 performs freeze substitution and progressive lowering of temperature (PLT) techniques and allows low temperature embedding and polymerization of resins.

The Leica EM FSP (freeze substitution processor), an automatic reagent handling system combined with the Leica EM AFS2, dispenses reagents for both freeze substitution and PLT applications. The LED illumination from within the chamber and the attached stereomicroscope for viewing and positioning of samples ensures ease of use.

The Leica EM AFS2 - Freeze Substitution and Low Temperature Embedding System

Key Features

Reduces set-up time

Automatic dilution of reagents from 100% stock containers reduces user reagent handling and set-up time.

One step preparation

Fast UV polymerization with LED UV lamp results in one-step preparation for the user; samples and reagents can be added and left until the end of the run.

Specimens remain dry

Adjustable transfer function of gaseous LN2 allows the chamber and specimens to remain dry, which results in no contamination of the specimen.
