SiN membranes – 200µm frame

  • Amorphous, low background, low scattering material
  • High resistance to acids, bases and solvents
  • High temperature resistant to >1000° C
  • Carbon free
  • Plasma cleanableLarge viewing area without grid bars
  • Clean, ultra-flat membrane surface
  • Optimised membrane stress to achieve strength and high planarity
  • Ideal support for multi-microscopy techniques such as TEM, SEM,
  • FIB, EDX, Auger, XPS and AFM/SPM

The standard silicon frame thickness is 200µm, which provide an easy to handle and sturdy support frame.

A thinner silicon support frame with 100µm thickness is also available. Please see: 100µm frames

Window sizes of 0.1 x 0.1, 0.25 x 0.25, 0.5 x 0.5, 1.0 x1.0 and 0.25 x 1.0mm.

Available with membrane thicknesses of 10, 20, 30, 50, 75, 100, 150, 200 and 500nm. Please click on the membrane thickness in the table below to see the options and pricing.

The choice of SiN membrane thickness and window size is dependent on a number of variables. Thinner membranes (10 -20 nm) are more suitable for higher resolution imaging, while thicker membranes (30-500 nm) are better for demanding sample preparation procedures. It is better to use thicker membranes and smaller window sizes when developing up new methods before moving on to thinner membranes and increasing window size for final imaging.
