An organo-silicon compound tetramethylsilane (TMS) is used as an internal standard for nuclear magnetic resonance (NMR). It is chemically inert and has a boiling point of 26.6°C which is lower than acetone (53.6°C), and other highly volatile liquids, such as diethyl ether (34.5°C) and 1,2-epoxy propane (36.4°C). It is soluble in most organic solvents but insoluble in water. All of these properties make TMS an ideal solvent for tissue drying, which preserves excellent tissue surface details. Dey, Sudip. Et al. (1989). A new rapid method of air-drying for scanning electron microscopy using tetramethylsilane. J. of Microscopy, Vol 156, pp. 259-261.

Xylene Substitute – Hemo-De® *
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…

Histosol™ - Xylene Substitute
Histosol™ is the original high flash point (114ºF TCC) histological clearing agent. It is intended to be used as a replacement for xylene where the hazards associated with aromatic hydrocarbon vapors are to be reduced. Museum-quality tissue slides can be prepared with Hitosol without change in protocol or procedure. Histosol is manufactured from petrochemical products and is miscible in all proportions with ethanol, isopropanol, and t-butanol. It is also miscible with all paraffin-based tissue embedding media and all permanent mounting materials.
