Freeze Substitution

Download PDF Brochure

The new Leica EM AFS2 is capable of freeze substitution and progressive lowering of temperature ( PLT ) techniques as well as allowing low temperature embedding and polymerization of resins. A stereomicroscope for viewing and positioning of the samples is available and the LED illumination from within the chamber makes work easy. The freeze substitution processor EM FSP is an automatic reagent handling system. Sitting on the EM AFS2, it dispenses reagents for both freeze substitution and PLT techniques.
