The A&D Weighing ION BM-300 Analytical Balance offers exceptional precision with a capacity of 320 g and readability of 0.1 mg. It features a built-in fan-less ionizer that neutralizes electrostatic charges instantly, enhancing accuracy without additional costs. The balance's large breeze chamber accommodates various sample vessels, while anti-static glass coating shields against external electrical interferences. Users can tailor response times with automatic or manual stabilization settings (FAST, MID, SLOW) based on environmental disturbances. Integrated sensors continuously track and display temperature, humidity, and atmospheric pressure to maintain optimal conditions.

This balance also includes an illuminated spirit level for quick leveling, enhancing accuracy and precision. With one-touch Full Digital Calibration and Auto Self Calibration, it adapts to onsite conditions and ambient temperature changes, ensuring consistent performance. The balance stores up to 200 data points and supports GLP/GMP/GCP/ISO compliant reporting, which includes detailed records such as manufacturer, model, and serial number, alongside calibration and audit details.

Additional functionalities include a reverse liquid crystal display, percent weighing, piece counting, and an underhook feature for below-balance weighing. Connectivity options include a standard USB and RS-232C interface, with optional Bluetooth and LAN Ethernet connections via WinCT-Plus software. The AD1688 Data Logger complements this setup by storing up to 5,000 points with time/date stamps for comprehensive data management. A 5-year US warranty guarantees long-term reliability, making the ION BM-300 a superior choice for precise analytical tasks.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
