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.


Sample Preparation Inner Status of K-kit


Wet Mode With Liquid


Thin Layer Mode Dried


Ordering Information Silicon Nitride


Observation Window: Material intrinsically tough, durable to withstand drastic pressure changes.


Streamline your preparation of liquid TEM samples with this new folding grid developed specifically for the K-kit. This low-cost single-use option eliminates the gluing and levelling steps required with a standard copper grid.
