Model 1070 – NanoClean

Key Features

Key features of the Fischione Model 1070 NanoClean include:

  • Simultaneously cleans specimens, specimen holders, and specimen mounts
  • No change to elemental composition or structural characteristics
  • Multiple gas inlets with mixing capabilities
  • Evacuates vacuum storage containers

Simultaneously Cleaning Of Electron Microscopy Specimens And Holders

The NanoClean automatically and quickly removes organic contamination (hydrocarbon) for microscopy applications. It simultaneously cleans electron microscopy specimens, specimen holders, and stubs and is also suited to surface science techniques.

The NanoClean features an easy-to-use touchscreen embedded module that allows the user to control individual instrument functions, such as delivered power, chamber pressure, gas mixture, and process time. For dedicated cleaning of electron microscopy specimens and holders, the NanoClean includes a recipe that yields optimal plasma processing conditions. Other recipes are available for applications, such as enhancing the hydrophilic properties of biological support grids.

Enhanced Imaging And Analysis

Cleaning is solely by reactive gas compounds formed by the plasma chemically reacting with carbonaceous material on the specimen and specimen holder. A low-energy, inductively coupled, high-frequency, downstream plasma effectively cleans the specimen surface, leaving the elemental composition and structural characteristics unchanged. It only takes 2 minutes to clean highly contaminated specimens.

Specimens that are not plasma treated have the tendency to conmtaminate electron microscopes with high brightness electron sources. The NanoClean eliminates this tendency by removing carbonaceous contamination, ensuring that imaging and analysis data, including fine probe microanalysis for extended periods is unaffected.

Features

The Fischione NanoClean employs and oil free vacuum system to prevent any organic contamination.

High throughput operation is made possible with the load-lock enabled chamber which facilittes rapid sample exchange.

The NanoClean features three mass flow controllers and is designed to accept multiple gases. Typically, users connect the tried and tested gas mixture of 25% oxygen and 75% argon to one of the gas inlet lines. The other gas inlet lines can be used to precision blend other feed gases via theNanoClean’s internal mass flow technology.

An automatic matching network ensures that the high-frequency power is effectively coupled to the plasma and the delivered power is suited for the application. The matching network regulates plasma power for a variety of conditions, objects to be processed, or gases employed.

Standard And Specialised Specimen Holders

The NanoClean is suited to both one or two side-entry specimen holders for all commercial transmission, scanning transmission, and scanning electron microscopes. An separate port allows large, bulk objects to be placed in the chamber for processing. This is ideal for scanning electron microscopy or surface science applications. A specialised specimen holder port allows the cleaning of specimens contained on carbon grids.
