NEW K-kit for Liquid TEM

Liquid TEM for Everyone

K-kit with TEM Holder

The K-kit is a single-use sealable carrier with a microchannel inside. It is made by ultraprecise MEMS micromachining from silicon, with a silicon nitride window. It fits inside a standard TEM grid and thus into all commonly used TEM holders.


The K-kit advantage:

  • Affordable and easy-to-use
  • No installation hassle
  • Image nano-objects in native state, no drying artifacts
  • Sealable carrier takes liquid sample directly to TEM
  • Fits all common TEM holders
  • Can preserve the sample for future re-examination


Now you don’t need to invest tens and hundreds of thousands to see your liquid or wet TEM samples in their native state. If you have access to a TEM, you can do liquid TEM. 

Fill, Seal and Observe
K-kit step by step use
The K-kit is easy. Just touch the carrier to a drop
of your liquid sample to have it drawn inside
by capillary force.
Seal ends with vacuum-proof Torr Seal® glue. Mount inside a standard grid for TEM.

Tools for Easy Loading and Mounting
K-kit container for loading and mounting
The K-kit container is designed to facilitate K-kit loading and mounting.
We offer the K-kit as a complete toolbox, set in a deluxe carrying case. The tools, together with the carrier container, are designed to make loading and mounting of the K-kit carrier easy even for an inexperienced user. The toolbox also includes a starter supply of the consumables, everything to get you started doing liquid TEM.
