Flex-Bio-LifeScience

The atomic force microscope that combines versatility and performance for biology and life science.

  • Techniques and applications for life science research
  • A design that opens up entirely new possibilities
  •  Discover all the practical details that really matter in daily use
  •  Discuss your application with one of our application scientists

A key success factor in life science research is the combination of multiple techniques. With the Flex-Bio, Nanosurf’s Bio AFM, you can combine the imaging, spectroscopy and nanomanipulation capacity of this system with the high-end optical techniques available for inverted microscopes.

Flex-Bio comes with manual and motorized stages for seamless integration on Zeiss, Olympus, Nikon and Leica inverted microscopes or with standalone stages. On the inverted microscope, optical and AFM data can be correlated, as shown here for internal limiting membrane (ILM) of the human retina.

For measurements that don’t need optical access from below, e.g. for the imaging and spectroscopy of samples like bacteriorhodopsin, a standalone stage makes the Flex-Bio compatible with the Nanosurf Isostage and Acoustic Enclosure 300, and generally makes the system much more compact.

Flex-Axiom – AFM for materials research

For success in materials research studies, scientists depend on professional tools that can readily provide the information needed, regardless of the tasks at hand. By advancing key technologies and designs, Nanosurf has made the Flex-Axiom one of the most versatile and flexible AFMs ever, allowing a large variety of materials research applications to be handled with ease. Together with the powerful C3000 controller, complex material characterizations are possible.

The Flex-Axiom is your reliable tool for topographical and metrological imaging of samples in both air and liquid. But the Flex-Axiom goes beyond topography, for example with advanced mechanical, electrical, or magnetic characterization. The system has also been successfully used for local sample manipulation.

The Flex-Axiom uses an extremely linear electromagnetic scanner for XY movement. This scanner delivers an average linearity deviation of less than 0.1% over the full scan range, top-ranking on the AFM market. The Z-axis is piezo-driven, with a position sensor that enables closed-loop operation. A sensitive cantilever detection system can measure well into the MHz frequency range. The scan head is connected to the full-featured, 24-bit C3000 controller with digital feedback and 2 dual-channel lock-in amplifiers.

Details

CoreAFM

The CoreAFM is the result of intelligently combining the core components of AFM to achieve maximum versatility and user-friendliness. Due to this fundamental design approach, the CoreAFM is equipped to perform AFM at its best.

The fusion of a modern flexure-guided scanner, XYZ sample stage, camera, active vibration isolation table, and acoustic shielding in a single all-in-one unit results in a complete AFM system with an unparalleled compact footprint. The system comes with a fully digital 24-bit controller developed specifically for the CoreAFM scanhead. All the essential functions of modern AFM are integral components of the CoreAFM system; all you need to do to take the CoreAFM into operation is connect the controller, and plug in power and USB.

Deeper system integration of the Isostage is reflected in the unique SpikeGuard, which eliminates glitches during imaging. Although the Isostage is an active vibration isolation system, glitches can still occur when distortions are too severe. SpikeGuard detects such anomalies and rescans the line for a distortion-free image.

Vitamin Analyzer

Since the human body cannot synthesize vitamins, they are typically acquired through external sources like food or nutritional supplements. That’s why the quantitative and qualitative analysis of vitamin takes very important part in food and pharmaceutical area.
Because vitamins are unstable compounds, which are easily oxidized and destroyed during sample preparation procedures, a simple analysis method that reduces degradation of vitamins needs to be established in order to produce accurate results.
YL Vitamin analyzer is designed for analysis of vitamins while overcoming these problems and producing accurate and reproducible results. With the column switching valve, it allows the trace level(ppb) of vitamin taking 3 steps which are pre-separation, concentration and analysis.
