Product description

Precision benchtop conductivity meter measuring conductivity, salinity, and TDS with temperature compensation.

The Thermo Scientific Orion Lab Star EC112 is a benchtop conductivity meter designed for accurate measurement of conductivity, salinity, and total dissolved solids (TDS) in laboratory and bioprocessing environments. Featuring a wide measurement range from 0.00 μS to 500.0 mS and temperature capability from -5.0 to 105°C, it supports critical applications in molecular diagnostics, biotechnology research, and biopharmaceutical production pipelines.

Key technical features include:

  • Large backlit display presenting mV and temperature simultaneously for enhanced usability
  • Support for 1 to 5-point conductivity/TDS calibrations and 1-point salinity and temperature calibrations to maintain SOP compliance
  • Data logging with storage for up to 500 data points, including date and time stamping, facilitating traceability and long-term data management
  • IP54 rating ensures splash resistance ideal for busy research and clinical labs
  • Compact footprint (12x13x7 inches) and lightweight design (4 lbs) optimize benchtop space utilization
  • Broad electrical compatibility (100-240V, 50/60 Hz) supports global laboratory standards

The Orion Lab Star EC112 is widely used in biomedical engineering, live-cell imaging workflows, and synthetic biology labs, making it an essential instrument for bioprocess monitoring and molecular cloning workflows that require precise electrolytic measurements. Its versatility and reliability make it a popular choice among molecular biology researchers and clinical diagnostics professionals involved in fluorescence analysis and cell imaging applications.

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.
