Cypher ES AFM
Environmental Control

Cypher is the first commercial AFM to take advantage of the high bandwidth and low noise performance of smaller cantilevers, and is the only commercial AFM to routinely resolve atomic point defects and the DNA helix. Now, Asylum Research introduces the Cypher ES, which adds full environmental control to the Cypher family. The heart of the Cypher ES is based around a cell constructed of inert materials, such as fused silica and FFKM, to enclose and control the sample environment. The modular design allows customization for measurements in nearly any environment.

 


 

Run Cypher ES in Any Environment

 

Gas/Fluid Perfusion in a Sealed Cell

  • Multiple ports for flow-through of gas and/or fluid

  • Perfusion may be performed in a droplet to minimize sample volume (<20µL) and cell cleaning

  • Simple gravity driven perfusion – no pumps are required

 

Integrated Temperature Control

  • Modular sample stages enable precise temperature control in several temperature ranges

  • No external boxes, additional electronics, or cooling pumps are required

 

Broad Chemical Compatibility

  • Ensuring chemical compatibility even in the harshest environments, cells are constructed with inert materials:

        - Fused silica

        - Perfluoroelastomer (FFKM)

        - PEEK

  • Suitable for solvents, acids, bases, buffers, inert gases

 

 

 

A) Sealed cell with fluid droplet

B) Cantilever-sample interface
     in droplet with perfusion tubes

 

 

User changeable sample stage for cooling/heating

 


 

Modular Design for Maximum Flexibility

The sealed cell is constructed from three components: cantilever holder, cell body, and sample stage. See below for specifications of the different versions of each component.

 

Sealed Cell

  • Modular and interchangeable

  • Supports positive pressure (up to 5psig) for gas/fluid perfusion

  • Fluid volumes as small as 20µL

Cantilever Holder

  • Fluid perfusion ports

  • Fused silica construction

 

Cell Body

  • Gas perfusion ports

  • Electrical feedthroughs

  • Fused silica construction

 

Sample Stage

  • Integrated cooling/heating in several temperature ranges

  • Variable material construction

  • FFKM diaphragm for distortion-free imaging

 

 


blueDrive Photothermal Excitation

The blueDrive Photothermal Excitation option makes tapping mode imaging simpler, more stable, and more quantitative. blueDrive produces an almost ideal cantilever response by directly exciting the cantilever photothermally. This provides significant ease of use and performance benefits for imaging topography, mechanical, electrical, and magnetic properties in air and liquids.
