"Spurr" Low Viscosity Kits

ERL 4221 has replaced ERL 4206. ERL 4221 has a higher viscosity than the previously used ERL 4206.

Spurr AR, 1969. A low-viscosity epoxy resin embedding medium for electron microscopy. J Ultrastruc Res, 26, p. 31.

Ellis, E Ann, Solutions to the Problem of Substitution of ERL 4221 for Vinyl Cyclohexene Dioxide in Spurr Low Viscosity Embedding Formulations, Microscopy Today, V 14, No 4, July 2006

The Spurr Kit gives excellent penetration for tough materials particularly in the studies of botanical, mineral and other hard biological specimens. When the mixture is kept at room temperature for 24 hours its viscosity will increase to 140cP, as is the case with other resins. When fully formulated, the Spurr’s resin will store in a deep-freeze for two months and at room temperature for two days. Curing is done at 70ºC for about 8 hours (see our Microwave system for significant time saving during epoxy processing).

Conductive Adhesives for SBEM



PELCO® Conductive Liquid Silver Paint

Composition:
1-Methoxy-2 Propanol base
60% Ag
Specific Gravity = 2.25 g/cc.
Viscosity = 455 poise

PELCO® Conductive Liquid Silver Paint

a reliable conductive ground path for SEM specimens
Air drying silver paint to make effective ground. Curable at room temperature and has high adhesion to any material. Surfaces do not have to be prepared prior to application and will adhere to such materials as polymer (phenolic) boards, ceramic, glass, metal, plastic and fiberglass. It should be mixed well with a spatula before using. RoHS compliant.

The container is offered in two sizes (15g and 30g) and is provided with an applicator brush. Silver flake grain size is an average of 80%, <1.0µm. Sheet resistance is 0.02 ohms per square @ 1 mil (0.001” = 0.025mm) thickness and is a function of the coating. Service temperature range is -40°C to 200°C.
Use #16021 gold/silver thinner/extender to dilute when needed.
