Liquid anhydride for curing epoxy resins. This material is a mixture of methyl isomers of methylbicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride. The larger the proportion of NMA used in the epoxy resin formula, the harder the resultant block.

Uvitex 2B fluorescent dye will bind to the chitin in fungal walls and is highly selective for fungi and algae in tissue sections. It has a slower fade rate than more commonly used fungal fluorescent dyes.

Resin for removal of phenolic inhibitors (hydroquinone monomethyl ether or t-butylcatechol) from neutral monomers, e.g., acrylate esters or styrene derivatives.

Suitable for use with Inhibitor Removal Column, Cat. #19708

2,4,6-Tris-(dimethylaminomethyl)phenol, ≥ 96%

Curing agent for epoxy resins.

Catalyst for polymerizing lactide and glycolide and isocyanate reactions.

Used as a replacement for hexenylsuccinic anhydride in Polyscience’s Ultra Low Viscosity Epoxy Embedding Kit (catalog # 17706)

Low viscosity epoxy accelerator.

(BDMA; N,N-Dimethylbenzylamine)

Liquid anhydride for curing low viscosity embedding resin for E.M., particularly used in Spurr formulations. Our material is specially distilled for E.M. applications and was developed in conjunction with Dr. Spurr.

Used in chloride-selective solvent polymeric membrane electrodes. Also used in the production of TDMAC-heparin which is used as an antithrombogenic coating for catheters and tubing.

Epoxy hardener, suitable for use in embedding procedures.

FLORISIL^® is a highly selective adsorbent that has extensive utility in preparative and analytical chromatography. Frequently referred to as a magnesium silicate. FLORISIL^® has become widely accepted in the analytical chromatography field for the separation and isolation of a variety of compounds.

Water indicating paste provides a fast, reliable way to detect water bottoms in storage tanks containing gasoline and gasoline/alcohol blends, diesel, jet fuel, fuel oil, solvents and other materials.
