Product description

Circular dichroism spectropolarimeter with 163–900 nm range, Peltier temp control 5–95°C, multimode measurement, stopped-flow accessory.

The Jasco J-815 is a state-of-the-art circular dichroism (CD) spectropolarimeter designed to analyse the chiroptical properties of biomolecules, providing critical insights into their secondary and tertiary structures. This instrument is essential for researchers aiming to understand protein folding, conformational changes, and interactions, particularly within the biotechnology sector.

Key features include:

Wavelength range: 163–900 nm, accommodating a broad spectrum of analyses.
Light source: 150 W air-cooled xenon lamp, ensuring stable and intense illumination.
Measurement modes: Circular dichroism, UV/Vis absorbance, linear dichroism, and fluorescence, offering versatile analytical capabilities.
Temperature control: Peltier element enabling precise thermal studies from 5°C to 95°C, crucial for thermal denaturation experiments.
Stopped-flow accessory: Facilitates rapid kinetics measurements, essential for studying fast biochemical reactions.

The J-815 is widely utilised in fields such as molecular biology, biochemistry, and pharmaceutical research. Its applications are particularly relevant in biotechnology, where understanding protein structures and interactions is vital for advancements in drug development, enzyme engineering, and synthetic biology.

Commonly found in university laboratories, biomedical research centres, and biopharmaceutical companies, the J-815 supports a range of studies, including:

Determining protein folding and conformational stability.
Characterising secondary structures like α-helices and β-sheets.
Investigating protein-ligand interactions and their effects on structure.
Assessing the impact of environmental factors such as pH, temperature, and denaturants on protein stability.

Introduced in 2006, the J-815 remains a cornerstone in chiroptical spectroscopy, reflecting Jasco's commitment to innovation and excellence in scientific instrumentation.

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.
