Product description

The X-Cite Tetrem XT640L is a programmable 4-channel LED fluorescence illuminator designed for advanced microscopy and live cell imaging applications. Covering excitation wavelengths from 380 to 660 nm, it includes LED peaks at 385, 475, 555, and 635 nm tailored for widely used fluorophores such as DAPI, FITC, mCherry/TRITC, and Cy5. The illuminator supports individual or simultaneous LED operation, optimizing excitation and minimizing bleed-through in multi-band filter setups.

Equipped with the proprietary smartDIAL™ controller, users benefit from intuitive manual control via large tactile buttons, an OLED display showing wavelength and intensity, and rapid LED ON/OFF response times (100 μs TTL, 1 ms USB). Connectivity options include TTL, analog intensity control, RS-232 commands with SDK support, and USB interfaces, making it adaptable for complex microscopy systems and automation workflows.

The compact unit measures 95 x 230 x 212 mm and weighs 3 kg, powered by a universal 24 VDC, 4.0 A external power supply. Certified for CE, RoHS, UKCA, and KC standards, it ensures safety and reliability. LEDs are warranted for 25,000 hours or 3 years, supporting sustained use in biotechnology research fields such as molecular diagnostics, fluorescence analysis, and bioprocessing workflows essential for synthetic biology and biomanufacturing pipelines.

This illuminator is widely used among researchers requiring a cost-effective upgrade from lamp-based systems, offering stable, high-intensity excitation essential in gene editing, live-cell fluorescence imaging, and routine microscopy tasks in biomedical engineering environments.

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?

Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
