Product description

TEM with 20–120 kV voltage, up to 700,000x magnification, LaB₆ source, EDS, CCD camera, multiple specimen holders.

The Tecnai 12 is a versatile transmission electron microscope (TEM) designed for high-resolution imaging and analysis of biological specimens and soft materials. Operating at accelerating voltages between 20 and 120 kV, this instrument delivers magnifications up to 700,000x, making it ideal for detailed ultrastructural studies.

Key features include:

  • LaB₆ electron source for enhanced brightness and stability.
  • Energy-dispersive X-ray spectroscopy (EDS) system capable of detecting elements from beryllium to uranium.
  • Gatan MSC794 CCD camera for high-quality digital image acquisition.
  • Multiple specimen holders, including single-tilt, double-tilt, and cryo-holders, accommodating diverse sample types.
  • Application-specific imaging modes, such as bright-field, dark-field, and convergent beam techniques.

Widely utilised in biotechnology, molecular biology, and materials science, the Tecnai 12 facilitates applications like:

  • Ultrastructural analysis of cells and tissues.
  • Nanoparticle characterisation in drug development.
  • Cryo-electron microscopy (cryo-EM) of protein complexes.
  • Elemental composition analysis of biological and synthetic materials.

This TEM is commonly found in university laboratories, biomedical research centres, and clinical facilities, supporting a broad spectrum of scientific investigations. Since its introduction, the Tecnai 12 has remained a reliable tool in the scientific community, with many units still operational today.

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.
