Product description

High-precision Ohaus Pioneer PX analytical balances with 120-220g capacity and 0.0001g readability, ideal for molecular diagnostics.

The Ohaus Pioneer PX Series Analytical Balances offer precise weighing solutions tailored for routine laboratory and biotechnology applications including molecular diagnostics, bioprocessing, and synthetic biology research. The series includes models PX124 (120 g), PX163 (160 g), and PX224 (220 g), all designed to deliver consistent analytical performance with readability down to 0.0001 g for PX124 and PX224 models.

Key technical features include:

  • High precision and repeatability: PX124 and PX224 models provide ±0.0002 g linearity and repeatability of 0.0001 g, supporting critical measurements in biomanufacturing and gene editing workflows.
  • Robust construction: Featuring a stainless steel weighing pan, metal base, plastic housing, and glass draft shield to minimize environmental variability and enhance durability in busy labs.
  • Selectable environmental filter modes: Stabilize weighing results even in typical lab environments fluctuating with airflow and vibrations.
  • Multiple application modes: Basic weighing, parts counting, percent weighing, animal/dynamic weighing, density determination, and formulation support diverse research and quality control workflows in biotechnology and clinical diagnostics.
  • Connectivity and security: RS-232 interface allows data transfer to PCs or printers for accurate documentation; integral menu lock and security bracket safeguard against tampering and unauthorized movement—essential for regulated laboratory settings.
  • User conveniences: Bright backlit LCD with dual display lines, auto tare, adjustable brightness, auto-dim function, and upfront leveling indicator facilitate ease of use for researchers.
  • Wide international unit support: Compatible with numerous weighing units including grams, milligrams, ounces, carats, and specialized Tael units accommodating global research standards.

Compact and versatile, the Ohaus Pioneer PX Series analytical balances are critical instruments widely adopted in molecular biology research, live-cell imaging experiments, and synthetic biology workflows. These balances efficiently support precision weighing tasks essential for bioprocessing, molecular cloning, and biopharmaceutical quality assurance, making them popular among laboratory professionals requiring reliable and accurate mass measurements.

Dimensions (approximate): 9" x 13" x 13" (WxDxH) Weight: 12 lbs Power: 120V AC adapter (12V - 0.5A input)

This series underscores Ohaus's commitment to precision, durability, and user-oriented design, providing foundational weighing capabilities indispensable for advanced biotechnology laboratories and clinical diagnostic settings.

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.
