High-throughput label-free protein analyzer enabling rapid biomolecular interaction analysis for biopharmaceutical research.
The Sartorius Octet R4 Protein Analyzer (Model OCTET-R4) is a precision label-free biomolecular interaction analyzer designed for rapid protein quantification and characterization. Optimized for high-throughput bioprocessing workflows in biopharmaceutical development, synthetic biology, and molecular diagnostics, this instrument supports essential analysis steps such as kinetic binding measurements and affinity profiling.
Key features include:
Technical specifications:
Widely adopted in biotechnological research such as gene editing, protein engineering, and molecular cloning workflows, the Sartorius Octet R4 is critical for biopharmaceutical production pipelines and synthetic biology research where precise biomolecular interaction analysis is paramount. Its label-free detection platform is particularly useful for live-cell and fluorescence analysis applications, supporting detailed kinetic assessments and affinity determinations essential to clinical diagnostics and biomedical engineering fields.
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.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
