Product description

200 kV field emission TEM/STEM with 0.19 nm resolution, EDS/EELS, tomography, and cryo-TEM capabilities.

Tecnai F20 is a versatile 200 kV field emission transmission electron microscope (TEM) designed for high-resolution imaging and comprehensive analytical capabilities. This instrument excels in both TEM and scanning transmission electron microscopy (STEM) modes, making it ideal for detailed structural and compositional analyses across various scientific disciplines.

Key features include:

High-resolution imaging: Achieves a point resolution of 0.24 nm in TEM mode and 0.19 nm in STEM mode, facilitating the observation of fine structural details.
Advanced analytical tools: Equipped with energy-dispersive X-ray spectroscopy (EDS) and electron energy loss spectroscopy (EELS) for precise elemental and chemical analysis.
Versatile specimen handling: Features a goniometer allowing tilt ranges up to ±40° with standard holders and up to ±80° with tomography holders, enhancing 3D imaging capabilities.
Cryogenic capabilities: Supports cryo-TEM applications with specialized holders, enabling the study of temperature-sensitive samples.
Integrated software: Incorporates user-friendly software packages for EDS, EELS, low-dose imaging, and tomography, streamlining complex analyses.

The instrument is widely utilized in fields such as:

Materials science: Investigating the morphology, crystallography, and elemental composition of metals, ceramics, and semiconductors.
Nanotechnology: Characterizing nanoparticles, nanocomposites, and thin films.
Life sciences: Examining biological specimens, including viruses and cellular structures, particularly through cryo-TEM techniques.

Commonly found in university laboratories, biomedical research centres, and industrial R&D facilities, the Tecnai F20 has been a cornerstone in electron microscopy since its introduction in the early 2000s. Its enduring relevance is attributed to its robust design and adaptability to evolving research needs.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
