Hemo-De xylene substitute
An intensive study from 1992 throughout 2000 has shown that Hemo-De (d-Limonene) a terpene-based chemical with a pleasant citrus fragrance, was able to replace many of the clinical laboratories toxic reagents, such as carbol-xylene, xylene, ethyl acetate and formalin.
In Parasitology – Hemo-De replaces ethyl acetate in the concentration procedure; Hemo-De replaces carbol-xylene, xylene and formalin in the trichrome procedure.
In Histology – Hemo-De replaces xylene in most all procedures. Hem-De is a superior solvent and Clearing agent that can be used in all tissue processing, deparaffiniating and slide preparation.
Hemo-De Features
- Soluble with alcohol and mounting media
- Biodegradable, non-corrosive, non-flammable (Combustible)
- Contains no benzene and no toluene
- Low toxicity levels
- Minimal tissue shrinkage
- Reasonably fast drying and leaves no residue
Hemo-De Application
In Research and Medical – Hematology, Cytology, Pathology, Microbiology, Histology, Pathology, Hospital
In Mechanical Applications – Cleaning of machine parts, cleaning tools, engines etc.
In Electronic Applications – Circuits boards, electronic components, tools.
General Applications – Clean metal and glass surfaces. Dilute with water can be used to clean all plastic surfaces. Removal of adhesives, glues, tars…
