FS1 Microscope Hot And Cold Thin Film Stage
Instec’s FS1 stage is designed specifically for drawing a freely suspended thin film across the aperture for analysis by thermal microscopy. The PCB sample holder allows an electric field to be applied across the film. Freely suspended films that are only a few molecular layers thick are very sensitive to contamination. The FS1 is designed so that all of the internal components can be removed and cleaned easily between experiments, reducing the risk of contamination from previous samples. Applications for this stage include liquid crystals, polymers, colloids, other complex fluids and optical tweezers.
Features
• Programmable precision temperature from -60°C to 200°C
• Dual heaters located above and below the sample chamber for superior temperature uniformity
• Thin film drawing kit
• Angled viewing aperture to reduce reflections
• Removable inner chamber for easy cleaning
• Extra large viewing aperture
• Removable and exchangeable windows
• Dual pane windows for better thermal isolation
• Integrated aperture window defrost system
• Precision X-Y micropositioner for in situ sample positioning
