DE-SOLV-IT

CITRUS-BASED SOLVENT AND MULTI-PURPOSE CLEANER

De-Solv-it cleaner is a highly effective citrus-based solvent for degreasing, dewaxing, adhesive spot and stain removal. In histology this solvent is used as a xylene substitute. De-Solv-it is not Class 3 Flammable (WorkSafe criteria), making it much safer than traditional hydrocarbon solvents.
De-Solv-it cleaner has no overwhelming vapours and requires no expensive additional protective clothing besides gloves and safety glasses. It is biodegradable and water miscible.
De-Solv-it cleaner can be used on many different surfaces: metals, glass, tile/formica, wood surfaces, ceramics, many plastics, carpet, clothing/fabrics. Do not use on silk, suede or leather.

D.E.R™ 732

Diglycidyl ether of polypropylene glycol, CAS/AICS Number: 26142-30-3 (9072-62-2)

Epoxy equivalent 305-335. D.E.R™ 736 is no longer available in Australia; D.E.R™ 732 is a close substitute, but has a slightly greater epoxy equivalent and requires 10% less accelerator in Spurr's formula.

D.E.R.™ 732 Liquid Epoxy Resin is a flexible, low viscosity, light color, epoxy resin for use in coatings and adhesives. This resin, with conventional bisphenol A based epoxy resins, imparts flexibility, elongation and improves impact resistance.

This resin serves also as a viscosity reducer, or can serve as the basis for advanced polymers for a variety of water-borne and solvent-borne coatings.

D.E.R™ 736
D.E.R™ 736 was recommended by Dr Spurr for his low viscosity medium. Unfortunately, the manufacturer is charged ~$10,000 by the Australian government when introducing chemicals new to this country, however closely related to accepted chemicals the new ones are. So we were counselled by the manufacturer that D.E.R™ 732 would work as well with a minor change in quantities only. It appears that, particularly when staining with Tol. Blue O using D.E.R™ 732, the resin itself is stained. We can bring in D.E.R™ 736 in small bottle quantities, but at a rather higher price than the D.E.R™ 732.

2,2-Dimethoxypropane (DMP)

Acetone Dimethyl Acetal, (CH3)2C(OCH3)2 F.W. 104.15 CAS #77-76-9

Used as a dehydration agent. DMP (2,2‐Dimethoxypropane, is a quick material for quickly processing tissue preparations for SEM and TEM. Initial dehydration with ethanol or acetone is recommended. DMP acts by chemically converting any remaining water to acetone. So complete dehydration is assured without special efforts to dry acetone or ethanol to achieve complete dehydration.

Specific Gravity: 0.849
