Clear-Advantage Xylene Substitute CH7g .....................................
Clear-Advantage is a specific fraction of petrochemical derivatives that creates a
safer xylene substitute for processing, staining and coverslipping. There are several
types of xylene substitutes in the market today including both standard hydrocarbon
and citrus limonene types that contain overpowering odors. Clear-Advantage is virtually
odorless and offers improved clearing performance compared to these types.

Methyl salicylate [119-36-8] HO5g ............................................
MW 152.15 bp 220-222°
Safe tissue clearing agent. Xylene substitute. J. Histotech., 9, 27 (1986)
ParaClear Odorless Xylene Substitute EH5g ....................................
Naphtha-petroleum derivative that replaces xylene for clearing. It is odorless
and presents a low hazard for routine histological processing and staining. Para-
Clear will remove alcohol during the final steps of routine tissue processing and
is miscible with paraffin for infiltration. It has a higher flash point than xylene,
reducing the flammability danger to the laboratory. Technical Data Sheet #671
Poly/Clear Solvent [5989-27-5] EHO4g .........................................
MW 136.2
A pleasant citrus odor replaces the strong xylene odor when you switch to Poly/Clear Solvent in your
laboratory as your paraffin clearing agent. This low-toxicity material is for use in histology and cytology
procedures when ever xylene is used. The high flash point and biodegradability of this product
makes it an attractive alternative. Poly/Clear is miscible with solvent based mounting media and
solubilizes both Polyfin ® and Peel-A-Way ® Technical Data Sheet #301
Tannic acid, EM grade [1401-55-4] HM4abg .....................................
(Tannin; Gallotannin; Gallotannic acid) MW 1701.23
Useful as an EM fixative for negative staining. Also useful for enzyme immobilization and protein
adsorption. J. Microscopy, 137, 57 (1985); J. Chromatogr., 207, 13 (1981)
Xylene, histology grade [1330-20-7] CH5g .....................................
MW 106.17
Used with Canada balsam in oil-immersion microscopy. Also as a clearing agent in microscope
technique. Merck Index, 11, 9988
