Laboratory vortex mixer Greiner model 3944-1 with 2800 rpm rotation speed for sample mixing in biotechnology applications.
The Greiner Vortex Mixer model 3944-1 / 845070 is engineered for efficient sample mixing with a rotational speed of 2,800 rpm (17,593 rad/min). Widely applied in biotechnology, molecular diagnostics, and bioprocessing laboratories, this benchtop vortex mixer supports thorough homogenization of liquid samples essential for workflows in gene editing and synthetic biology research.
This vortex mixer is crucial for biomanufacturing process development where consistent sample agitation is needed, and remains popular among researchers requiring reliable mixing in clinical and research labs.
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.
