Reliable VWR VM-300 analog vortex mixer with speed control, ideal for mixing small liquid samples in biotechnology workflows.
The VWR VM-300 Analog Vortex Mixer is engineered for precise and efficient mixing of small vials and tubes in laboratory settings. Featuring an analog speed control knob, this benchtop vortex mixer provides variable agitation speeds tailored to sample requirements. The compact unit measures 5.5 x 4.5 x 7 inches and weighs 3.5 lbs, making it suitable for limited bench space. Operating with a voltage of 120 V and frequency of 60 Hz, it is designed for routine mixing tasks common in biotechnology, molecular diagnostics, and synthetic biology research. The included rubber cup attachment ensures secure sample holding and effective mixing. This vortex mixer is essential for workflows involving molecular cloning, bioprocessing, and biochemical sample preparation, supporting consistent sample homogenization critical for reproducible results in biopharmaceutical production pipelines and live-cell imaging sample prep.
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.
