Spurr Low Viscosity Embedding Kit is a low-viscosity epoxy embedding formulation designed for rapid infiltration into tissues, minerals, and other dense structures. The approximately 60 cps viscosity allows effective penetration into difficult specimens and supports embedding workflows requiring deep infiltration.
This formulation is commonly used in microscopy sample preparation, particularly for specimens with high lipid content, hard membranes, highly vacuolated parenchymatous tissues, and mineralized materials.
The kit may also be used in preparation of mineral specimens for polishing and sectioning applications where low-viscosity resin systems are beneficial.

Applications
Tissue Embedding
Commonly used for embedding biological tissues requiring deep resin penetration, including specimens with high lipid content or dense membrane structures.
Mineral & Hard Material Preparation
The low viscosity formulation supports infiltration of mineralized specimens and dense materials prior to polishing or sectioning.
Electron Microscopy Sample Preparation
Frequently used in microscopy laboratories for resin embedding applications where rapid infiltration and specimen support are important.
Dense & Vacuolated Structures
Suitable for highly vacuolated parenchymatous tissues and other challenging specimens that benefit from low-viscosity embedding systems.
Preparation & Handling Considerations
- Low viscosity supports rapid infiltration into dense specimens
- Embedding performance depends on specimen preparation and processing conditions
- Proper resin mixing ratios are important for final curing characteristics
- Users should follow established laboratory embedding protocols
Final embedding quality and infiltration performance depend on specimen composition, dehydration procedures, infiltration time, and curing conditions.
Handling & Storage
- Store components tightly sealed in a cool, dry environment
- Avoid contamination during resin preparation
- Use appropriate laboratory PPE and ventilation
- Follow standard epoxy resin handling procedures
