Filgen - Vacuum Staining System For Polymer TEM/SEM Imaging
FilgenHigh performance and multi-functional polymers have important technical roles for many fields. Analysis of morphology for multi-component polymers through TEM / SEM image is critical to develop these high performance polymers. With good staining technique, new polymer morphology can be well-observed. Vacuum staining system by Filgen is an excellent solution for your new polymer material research and development.
- Heavy metal staining for new polymer materials to get contrast for TEM/SEM image
- Solidifying sample for ultra microtome slice for TEM/SEM imaging
Why heavy metal stain for TEM / SEM polymer imaging ?
- Polymer materials are light elements (C,H,N,O). Electron beam pass through these elements and electron beam scattering does not happen at these elements.
- With heavy metal staining, electron beam is scattered differently at these elements. You can see structure of new polymer materials with good contrast.
- TEM: stained part become dark color
- SEM: stained part become bright color
- Film for battery
- Insulation material for semi-conductor
- Safe stain in closed system for Osmium tetroxide and Ruthenium tetroxide
- Excellent stain process control by good vacuum and gas system
- Easy auto process by touch panel instruction
- Heating option up to 70 degrees C for better Osmium tetroxide staining
- Gas density & temperature for 4 chambers set separately
- Hygroscopic sample staining possible in vacuum
- Solidifying sample for ultra microtome slice
- SEM Charge-up prevention by Ruthenium tetroxide
Only for RuO4
Some polymers can be stained better in higher temperature because molecular motion can be more active and chemical reaction can be more accelerated.
- Maximum temperature : 70C ( most of polymers have heat resistance up to 70C )
- Temperature for each chamber can be set separately (heater and temperature sensor located under 4 chambers)
- No cooler in the system
- Only for OsO4 (RuO4 is very reactive)
Good example : Nylon and PVA (polyvinyl alcohol) were well stained at 70C in the system, compared to room temperature
Sample Chamber Option
Atmosphere non-exposure chamber
- Useful to avoid samples exposed to air including pre-staining process and post-staining process
- Small chamber (5ID x 6H mm) good for higher density staining gas
- Middle chamber (47ID x 15H mm)
Sample grid holder
- Prevention of grid dispersion during vacuuming
- 8 grids set in 45mm diameter stage
