Product description

Multi-mode benchtop pH meter for precise pH, mV, ORP, and temperature measurements with data logging.

The Thermo Fisher Scientific Orion Versa Star Pro is a versatile benchtop electrochemistry meter, engineered for advanced laboratory workflows requiring accurate pH, mV, relative mV, ORP, and temperature measurements within a unified platform. Ideal for applications in molecular diagnostics, bioprocessing, and quality control laboratories, this instrument supports diverse analytical needs without necessitating multiple devices.

Key technical features include:

  • Measurement ranges: pH (-2 to 20), mV/ORP (±2000 mV), temperature (-5°C to +105°C)
  • High accuracy: pH ±0.002, temperature ±0.1°C, mV ±0.2 or 0.05%
  • Calibration flexibility: 1 to 6 calibration points for pH, with editable options for relative mV and ORP
  • Data management: Internal storage for 2000 data points with date/time stamps, data export via USB and RS-232 supporting traceability and documentation standards
  • User interface: Color graphic LCD with customizable display options for real-time monitoring, calibration status, and measurement history
  • Durability: IP54-rated housing to resist dust and splashes, compact design suited for crowded benchtops or wall mounting

This meter is widely used in biotechnology research, including gene editing workflows and synthetic biology studies, as well as clinical diagnostics where reliable electrochemical measurements are critical. Its robust design combined with precise calibration and extensive data logging capabilities make it essential for biopharmaceutical production pipelines and molecular cloning laboratories.

The compact and reliable Orion Versa Star Pro enables laboratories to streamline electrochemical testing, enhancing productivity in environments requiring high-precision biochemical analysis and fluorescence assay support.

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.
