Description

Lr White Resin Ready-To-Use is a pre-formulated, low-viscosity acrylic embedding medium designed for electron microscopy sample preparation. This product matters because it offers exceptional consistency and ease of use, eliminating the need for complex mixing and degassing procedures, which accelerates workflow and improves reproducibility. It is an essential material for histology, pathology, and materials science laboratories requiring high-quality, ultra-thin sectioning for TEM analysis. The resin polymerizes at low temperatures to preserve delicate ultrastructural details.

Application

Lr White Resin Ready-To-Use is a specialized polymer with key applications in advanced microscopy and sample preparation.

• Transmission Electron Microscopy (TEM): Primary embedding medium for biological tissues, cells, and polymers.
• Immunogold Labeling: Ideal for immunocytochemistry studies due to its hydrophilic nature and antigen preservation properties.
• Light Microscopy: Can be used for semi-thin sectioning and staining for correlative light and electron microscopy (CLEM).
• Materials Science: Embedding of soft materials, nanocomposites, and delicate specimens for ultrastructural analysis.
• Botanical & Plant Science: Infiltration and embedding of plant tissues for cellular studies.
• Pathology Research: Preparation of diagnostic and research tissue samples for high-resolution imaging.

Quality Control

Every batch of our Lr White Resin Ready-To-Use is manufactured and tested under strict quality protocols to ensure performance critical for electron microscopy. We guarantee batch-to-batch consistency in viscosity, curing properties, and ultrastructural preservation. A comprehensive Certificate of Analysis (COA) detailing purity, clarity, and polymerization characteristics is provided with each shipment to support your quality assurance and research documentation.

Storage

Preserve in the original tightly closed container, protected from light. Store in a cool, dry place at temperatures between 2°C and 8°C (refrigerated) to maximize shelf life and prevent premature polymerization. Keep away from heat, sparks, and open flames. Ensure good ventilation in the storage area.
