OVERVIEW K-kit Adaptability Compatible with all kinds of TEM Holders = K-Kit FEI TECNAI F20 Holder Strong Structural Reliability under Vacuum
Silicon Body (MEMS technology): Use a Si-based structure, ensuring strength and reliability. (MEMS, Micro-Electro-Mechanical Systems)
Torr Seal® Epoxy: A trusted and widely-used
glue, suitable for high-vacuum systems. (Torr Seal®
, a trade mark owned by Agilent Tech. Inc.) Sealing glue compatible with many solvents
The following table shows the test results of Torr Seal Epoxy soaked in chemical solvents for 24 hours and then examined using FTIR (if dissolved), and visual observation (if dispersed).

Wet and Thin Layer Mode of K-kit The K-Kit can be used in either Wet Mode or Thin Layer Mode. Wet Mode: The loaded liquid sample is sealed and imaged using TEM in the native liquid environment.
Thin Layer Mode: A patented liquid drying protocol preserves the original morphology and physical state of nanomaterials with improved imaging resolution.
