Product description

Refillable glass pH electrode measuring 0-14 pH, operates 0-80°C, with ceramic junction and 3 mol/L KCl electrolyte.

Mettler Toledo LE409 pH Electrode

The Mettler Toledo LE409 is a high-quality, refillable glass pH electrode designed for precise and rapid pH measurements across a broad spectrum of aqueous samples, including acids and bases. Its robust construction and reliable performance make it an essential tool for laboratories requiring accurate pH analysis.

Key features:

  • Wide pH range: Capable of measuring pH values from 0 to 14, accommodating diverse sample types.
  • Broad temperature compatibility: Operates effectively between 0°C and 80°C, suitable for various laboratory conditions.
  • Refillable electrolyte system: Utilises a 3 mol/L KCl liquid electrolyte, ensuring consistent performance and extending electrode lifespan.
  • Durable glass construction: Provides chemical resistance and longevity, ideal for routine laboratory use.
  • Ceramic junction: Ensures stable and reliable measurements by facilitating efficient ion exchange.

Applications:

  • Biotechnology: Essential for processes such as bioprocessing, molecular diagnostics, and biomanufacturing, where precise pH control is critical.
  • Molecular biology: Widely used in molecular cloning workflows and gene editing experiments requiring accurate pH conditions.
  • Clinical diagnostics: Integral in laboratories conducting pH-dependent assays and tests.
  • Environmental science: Employed in water quality testing and environmental monitoring to assess pH levels.

Commonly used in:

  • University laboratories: Supporting academic research and teaching in various scientific disciplines.
  • Biotechnology companies: Facilitating research and development in bioprocessing and synthetic biology.
  • Clinical laboratories: Conducting diagnostic tests requiring precise pH measurements.
  • Environmental research centres: Monitoring and analysing environmental samples for pH-related studies.

First introduced prior to 2025, the LE409 continues to be a reliable and cost-effective solution for laboratories seeking accurate pH measurement capabilities.

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.
