Jeol JFD-V

Product catalog summary

Overview
The JFD V Freeze Fracture System by Boeckeler Instruments is a high vacuum cryogenic system designed for producing metal replicas of cryofixed and fractured specimens. It features an elegant design that simplifies operation and ensures repeatable results.

Key Features

Equipped with electron guns allowing for 30 or more evaporations between maintenance.
Specimens and knives are transferred using an eccentric rod for easy attachment.
Shadowing angles can be set rapidly and precisely, with tilting available during the shadowing process.
System is user-friendly, allowing unskilled operators to perform experiments easily.
Offers clean, versatile replication with a comfortable and reliable operation.

Technical Specifications

Ultra high vacuum turbopumped chamber with a large viewing window.
Vacuum load lock system for sample loading and knife changing.
Electron beam guns housed in a separate high vacuum chamber.
LN2 cooled anti-contamination shield surrounding the specimen.
Precise temperature control of the Liquid Nitrogen cooled specimen stage with digital displays for both specimen and knife holder temperatures.

Operational Details
The JFD V processes ultra-rapidly frozen samples into high-quality replicas within minutes. It uses a vacuum load lock system for changing microtome blades without affecting the main chamber vacuum. Samples undergo a series of processes including loading, fracturing, etching, shadow casting with platinum, and stabilization with carbon, at a rate of 4 to 5 samples per hour. The system operates at temperatures down to -170°C.

Additional Features

Motor-driven rotating specimen holder with 0-90° tilt for shadowing.
Self-contained 1-liter LN2 Dewar for rapid cooling.
Protection from contamination via LN2 cooled anti-contamination shield and high-speed turbo molecular pump.
Electron beam guns for platinum and carbon film evaporation are housed in an independent chamber, allowing material changes without breaking the main chamber vacuum.
Brightly illuminated main sample vacuum chamber with an internal LED system and 10x binocular microscope for specimen viewing.

The JFD V Freeze Fracture Instrument is a stand-alone, fully integrated, high vacuum cryogenic system for the production of metal replicas of cryofixed & fractured specimens. Complete with unique vacuum load lock sample insertion holder, the JFD V processes ultra rapidly frozen samples into high quality replicas in just a matter of minutes. The same vacuum load lock system is utilized for changing microtome blades without interfering with the main chamber vacuum. 1 liter LN2 Dewar is directly linked to the sample stage for rapid cool down to -170C or lower in just a matter of minutes.
