High-precision A&D BM-20 microbalance with 22 g capacity, 0.001 mg readability, and fanless ionizer for static charge neutralization.
The A&D BM-20 microbalance is a laboratory-grade analytical balance designed for ultra-precise weighing tasks essential in molecular diagnostics, bioprocessing, and synthetic biology research. It offers a maximum capacity of 22 g combined with a resolution of 0.001 mg and exceptional repeatability at 0.0025 mg, making it suitable for handling sensitive biochemical samples and fine powders where minimal measurement deviation is critical.
Key technical features include a built-in fanless ionizer that effectively neutralizes static charge without airflow disturbance, preserving the integrity of light and sensitive samples in live-cell imaging preparations and fluorescence analysis workflows. The balance incorporates antistatic glass panes to further mitigate external static influences, such as from charged laboratory clothing.
The BM-20 stabilizes readings quickly within approximately 10 seconds (FAST mode). It includes an internal weight calibration system allowing one-key sensitivity adjustment, ensuring constant high accuracy indispensable for precision weighing in biotechnology and biomedical engineering applications.
Enhanced data management capabilities allow storage of up to 200 weighing results internally, reducing reliance on external memory devices. Connectivity options include USB and RS-232C ports for seamless data transfer to PCs, facilitating integration into laboratory information management systems (LIMS) and biomanufacturing quality control procedures. Password protection secures data integrity by restricting unauthorized access.
This microbalance supports critical tasks in molecular cloning workflows, synthetic biology research, and biopharmaceutical production pipelines where accurate microgram measurements define success. The A&D BM-20 is a reliable instrument favored for precision and stability in clinical diagnostics and neuroimaging sample preparation.

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.
