Training for in situ holder setup, operation, and workflows
We periodically host trainees from universities, national laboratories, or private laboratories that own our holders. During these training classes we demonstrate and practice using all hardware and the complete workflow for experimental set up and best practices for image acquisition with hands-on instruction. Classes are held for liquid cell holders, gas cell holders, and biasing-manipulator holders.
The standard 2-day class covers the complete workflow and advanced configurations, exploration of applications, and experimentation in the TEM. The express 1-day class is helpful for experienced researchers who want to refresh their skills. If you have specific experimental challenges that you would like to solve for planned or ongoing experiments, let us know so we can discuss ahead of time how best to assist you.
We are currently gauging interest for classes for Q3, and Q4 for 2026 for the following in-situ holders. Dates will be finalized with the first two trainees to confirm for a particular week.

Liquid Cell and Optical Liquid Cell training course dates*
- Q3 2026: TBD 7/6 – 9/28
- Q4 2026: TBD 10/5 – 12/14

Gas Cell and Optical Gas Cell training course dates*
- Q3 2026: TBD 7/6 – 9/28
- Q4 2026: TBD 10/5 – 12/14

Frequently asked questions
Hummingbird Scientific training classes provide hands-on instruction for in-situ TEM experiments, including holder setup, environmental cell assembly and seal checking, tubing assembly, gas and liquid flow control, sample preparation, microscope alignment, experimental workflows, image acquisition, troubleshooting, and best practices for liquid cell, gas cell, and nano-manipulator holders.
These courses are designed for graduate students, postdoctoral researchers, facility staff scientists, principal investigators, and industrial researchers who use liquid cell TEM, gas cell TEM, electrical biasing, or nano-manipulation techniques.
Yes. Participants can discuss specific experimental goals before the class, including catalysis, electrochemistry, battery research, corrosion, materials synthesis, semiconductor devices, and operando microscopy workflows. Trainees can even bring their own samples for the hands-on TEM portion of the class and may save their data for later use.
Both new and experienced liquid-cell TEM users can attend. The standard two-day course provides comprehensive training, while the one-day express course is intended for experienced researchers seeking a refresher on holder operation and experimental workflows. This is not course in TEM operation or imaging, so trainees should arrive with a strong background in TEM theory and hardware operation, unless training for an SEM or X-ray environmental sample holder.
Training sessions can be tailored to address real-world experimental challenges, such as achieving stable liquid flow, maintaining gas environments, reducing contamination, improving image quality, optimizing electrical contacts, developing sample preparation workflows, and designing successful in-situ TEM experiments. If you have a specific application such as catalysis, batteries, electrochemistry, particle self-assembly, corrosion, or device section biasing, please let us know what you are planning and we will be prepared to advise and accommodate you.
Training classes can accommodate individual researchers or small groups from the same institution. Group training allows multiple team members to learn consistent workflows, helping labs establish standardized procedures for future experiments. Typically we looks for at least two trainees to schedule a training on a particular day, but we can accommodate up to four trainees for a single two-day session.
Yes. Training is strongly recommended before performing liquid cell TEM experiments. Unlike conventional TEM imaging, liquid cell experiments involve the integration of specialized hardware, microfabricated chips, fluid delivery systems, microscope operating conditions, and experiment-specific workflows. Even small mistakes during assembly, sample loading, or operation can result in window damage, liquid leakage, contamination, poor image quality, or failed experiments.
For many researchers, training significantly shortens the learning curve associated with liquid cell TEM and helps ensure that valuable microscope time is used efficiently. By gaining practical experience under expert guidance, users can confidently set up experiments, troubleshoot issues, and collect reproducible data for their applications.
