Compact benchtop densitometer measuring turbidity and optical density in microbial and cell cultures.
The Grant Bio DEN-1 is a compact benchtop turbidity and densitometer designed for precise measurement of optical density and turbidity in life-science and microbiology laboratories. This instrument is engineered to quantify the optical density (OD) of microbial and cell suspensions, including bacterial and yeast cultures, making it critical for applications such as:
The DEN-1 supports biotechnology research involving cell growth monitoring, microbial quantification, and live-cell analysis where precise optical density readings impact molecular cloning and synthetic biology applications. Its benchtop format is ideal for laboratory settings requiring consistent and reliable turbidity measurements in biotechnology and clinical diagnostics contexts. This device is widely used by molecular biology researchers, biotechnologists, and microbiologists involved in fermentation technology and biomedical engineering research.
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.
