Product description

Precision analytical balance with 220 g capacity, 1 mg readability, touchscreen, and multi-application support.

The Ohaus Precision Balance EXR223 is a high-accuracy analytical balance designed for advanced laboratory weighing tasks critical in biotechnology, molecular diagnostics, and bioprocessing workflows. Featuring a maximum capacity of 220 g and a readability of 1 mg, the EXR223 ensures precise measurements essential for formulation, density determination, and parts counting applications widely adopted in synthetic biology research.

Key technical features include:

  • 7-inch TFT 16.7M color touchscreen display with glass overlay for intuitive navigation and clear data visualization.
  • Multiple weighing modes such as Basic Weighing, Parts Counting, Check Counting, Percent Weighing, Dynamic Weighing, Totalization, Differential, Density Determination, and Peak Hold, enabling versatile lab workflows.
  • Robust communication interfaces: USB Host (x2), USB Device (Type C), Ethernet (RJ45), RS232, with optional Wi-Fi and Bluetooth dongles for seamless connectivity in laboratory information management systems (LIMS) important in biomanufacturing environments.
  • Durable construction with metal housing, SST 316 stainless steel weighing pan (130 mm x 130 mm), and an anti-static glass draft shield with 2 touchless sensors to minimize environmental interference.
  • Advanced usability features such as AutoCal™ internal automatic calibration, time synchronization via NTP, 4-level user management, and a 100,000-entry system log facilitate compliance and traceability in regulated biopharmaceutical production pipelines.
  • Supports a wide range of units including grams, milligrams, carats, taels, ticals, and ounces supporting international laboratories and specialized biotech measurements.

Operating conditions are optimized for controlled lab environments (10°C–30°C, 80% RH non-condensing) with a rapid stabilization time of 1.5 seconds and excellent repeatability at 1 mg, attributes indispensable for live-cell imaging preparations, molecular cloning quantifications, and clinical diagnostics.

This precision balance is an essential instrument for laboratories focused on molecular biology, cell imaging, and fluorescence analysis, providing reliable, high-resolution weighing data that underpin critical processes in gene editing and bioprocessing. Its modular connectivity and robust design make it a popular choice among researchers demanding accuracy and efficiency in their analytical balance for biomedical engineering and synthetic biology experiments.

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.
