LKB 7800 Knifemaker – Precision Glass & Diamond Knife Fabrication System

The LKB 7800 Knifemaker is a precision instrument designed for producing high-quality glass and diamond knives used in ultramicrotomy. Trusted in histology and electron microscopy laboratories, the 7800 delivers consistent, reproducible knife edges essential for ultrathin sectioning of biological and materials samples.

Built with LKB’s hallmark mechanical accuracy, the 7800 allows controlled breaking and shaping of glass strips to create knives suitable for light microscopy, transmission electron microscopy (TEM), and cryo-applications. Its rigid frame, fine adjustment controls, and stable cutting geometry help minimize defects and edge irregularities, resulting in cleaner sections and reduced sample damage.

The system is well-suited for research labs, academic institutions, and core facilities seeking a reliable, cost-effective alternative to outsourcing knife production. When paired with compatible ultramicrotomes, the LKB 7800 supports high-throughput workflows while maintaining precision standards required for advanced microscopy.

Common applications include:

• Glass knife fabrication for ultramicrotomy

• Histology and pathology sectioning

• TEM and materials science preparation

• Cryo and resin-embedded sample work

Key features:

• Precision glass knife breaking mechanism

• Stable, vibration-resistant construction

• Fine mechanical adjustments for repeatability

• Designed for microscopy and ultramicrotome workflows
