Robust UV-Vis spectrophotometer with pulsed deuterium lamp, silicon photodiode detector for nucleic acid/protein quantitation.
The Amersham Pharmacia Biotechnology Gene Quant Pro 4224 is a benchtop UV-Vis spectrophotometer optimized for precise quantitation of nucleic acids and proteins, widely used in molecular diagnostics and biotechnology research. It features a long-life borosilicate glass pulsed deuterium lamp as the light source, ensuring stable UV light emission critical for spectrophotometric analysis at key wavelengths (230, 260, 280, 320 nm). The silicon photodiode detector offers high sensitivity and a broad photometric range (up to ±3.000 absorbance units), suitable for detecting low to moderate concentration biomolecules.
Its optical system delivers excellent linearity (±1.0% or ±0.005 A) and photometric reproducibility (0.5%), essential for consistent results in molecular cloning workflows, gene expression quantification, and protein assays. The instrument exhibits minimal stray light (<0.1%T at 220 nm), which is critical for accurate absorbance measurements in complex biological samples. Data output is facilitated via standard Centronics parallel port or a 9-pin serial interface, enabling integration with laboratory information management systems.
With compact dimensions (32 × 40 × 16 cm) and a weight of 4 kg, this spectrophotometer is suitable for laboratories requiring dependable instrumentation without large footprint demands. It operates on universal power input (90–265 VAC, 50/60 Hz), making it adaptable to various lab environments.
Note: This unit is sold as a used instrument, offered "as is." Performance and function may not fully conform to new-product specifications and should be confirmed prior to deployment. It remains a valuable tool for biotechnology applications such as bioprocessing, gene editing verification, and molecular diagnostic workflows, where reliable UV-visible spectrophotometric data is vital.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
