Product description

Precision balance with 4200 g capacity, 0.01 g readability, 7" color touchscreen, and advanced weighing modes.

The Ohaus EXR4202N Precision Balance offers highly accurate weighing solutions essential for *biotechnology*, *molecular diagnostics*, and *clinical laboratory* applications. This precision weighing scale features a maximum capacity of 4200 g with an exceptional readability of 0.01 g, suitable for precise quantification required in bioprocessing and synthetic biology workflows.

Key technical specifications include:

  • 7-inch TFT 16.7M color touchscreen with glass overlay for intuitive user interaction and efficient data input.
  • Multiple advanced weighing modes: *Basic Weighing, Parts Counting, Check Counting, Percent Weighing, Check Weighing, Dynamic Weighing, Totalization, Formulation, Differential, Density Determination,* and *Peak Hold* — ideal for diverse laboratory protocols including gene editing and biomanufacturing quality control.
  • Robust construction with a stainless steel (SST 316) weighing pan, metal housing, and anti-static glass draftshield to minimize environmental interference, crucial for sensitive *live-cell imaging* sample preparations.
  • Comprehensive connectivity options: USB Host (Type A) x2, USB Device (Type C) x1, Ethernet (RJ45), RS232, and optional WiFi/Bluetooth dongle for seamless integration with laboratory information management systems (LIMS), supporting data integrity and traceability.
  • Features such as AutoCal™ internal automatic calibration, time synchronization via NTP, HID support without driver installation, and multi-level user management with a system log capacity of 100,000 entries enhance reliability and compliance in regulated environments.
  • Dimensions of 391 mm x 95 mm x 229 mm (LxHxW) and a net weight of 4.9 kg provide a benchtop footprint compatible with most laboratory settings.
  • Certified NTEP Legal for Trade, making it suitable for regulated pharmaceutical and clinical diagnostics settings.

This precision balance is an excellent tool for researchers requiring precise mass measurement in *molecular cloning workflows* and *biopharmaceutical production pipelines*. Its broad functional modes and high-capacity range make it a versatile instrument widely adopted in *biotechnology* and *clinical research* 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?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
