Product description

The Ohaus Analytical Balance EXP124N/AD (model 31059180) is a high-precision laboratory weighing instrument engineered for diverse applications in molecular diagnostics, biotechnology, and clinical research. Designed to deliver accurate results with a maximum capacity of 120 g and a readability of 0.1 mg, it supports critical bioprocessing workflows requiring exact mass measurements.

Key features include:

  • 7-inch TFT 16.7M color touchscreen with glass overlay for intuitive operation and clear data visualization
  • Extensive application modes: Basic Weighing, Parts Counting, Percent Weighing, Check Weighing, Dynamic Weighing, Totalization, Formulation, Differential Weighing, Density Determination, and more, supporting tasks in synthetic biology and biomanufacturing
  • Robust construction featuring a modular metal base and housing, a SST 316 stainless steel pan (90 mm x 90 mm), and an anti-static glass draftshield facilitating precise measurements in contamination-sensitive environments
  • Built-in ionizer and motorized leveling system with two touchless sensors ensure sample stability and minimize environmental interferences important in molecular cloning workflows
  • Advanced communications suite includes USB Host (Type A), USB Device (Types B & C), Ethernet (RJ45), RS232, with optional WiFi and Bluetooth dongle integration for seamless connectivity within laboratory information management systems (LIMS)
  • Automatic internal calibration via AutoCal™ maintains measurement integrity without manual intervention
  • Legal-for-trade compliance certified by NTEP, suitable for regulated environments and quality control procedures in biomedical engineering and clinical diagnostics
  • Additional design innovations: anti-pinch automatic doors, sample spotlight, status lights, and multi-level user management with a system log capacity of 100,000 entries secure traceability and operational safety

Operating in controlled environments from 15°C to 25°C with up to 80% relative humidity (non-condensing), this balance is ideal for precise mass measurements in analytical laboratories focused on biotechnology research, live-cell imaging preparation, and molecular assays. The combination of sophisticated weighing modes and hassle-free connectivity makes the EXP124N/AD a critical instrument in biopharmaceutical production pipelines and synthetic biology research environments.

This analytical balance’s enhanced features and precise calibration also make it indispensable for applications such as peak hold measurements, pipette adjustment, statistical quality control (SQC), fill weight variation assessments, and flow rate control in industrial and academic settings.

Optimize your molecular biology workflows with the Ohaus EXP124N/AD Analytical Balance, engineered for accuracy, durability, and advanced connectivity in modern biotechnology laboratories.

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.
