Product description

Portable pH meter with Swiss LabSen 861 electrode, IP57 waterproof, USB data output, ideal for high-temp, caustic liquids.

The Apera Instruments PH8500-HT Portable pH Meter is engineered for robust, accurate pH measurement in challenging environments, including high-temperature liquids and caustic solutions critical to molecular diagnostics and bioprocessing workflows. Equipped with the Swiss LabSen 861 pH Electrode, this meter incorporates:

  • PHY glass membrane, highly resistant to chemical corrosion, ensuring extended electrode service life in complex, high-temp chemical testing setups.
  • PTFE ring junction designed to prevent clogging from harsh chemical samples, critical for maintaining measurement accuracy in biomanufacturing and synthetic biology applications.
  • Silver-ion-trap reference system that absorbs exuded silver ions (Ag⁺) preventing interference by sulfides, proteins, or TRIS buffers, enhancing reliability in molecular biology and clinical diagnostics.

Key technical features include:

  • GLP-compliant data management with 500 data set storage capacity and USB output for seamless data transfer and analysis.
  • Intelligent functions such as self-diagnosis of out-of-range values, electrode invalidation alerts, automatic calibration with slope display, and auto power-off to optimize laboratory workflows.
  • Rugged design featuring an IP57 waterproof rating and soft silicone case for durable use and ergonomic handling in field and benchtop environments.
  • Large LCD screen displays pH, temperature, calibration status, and data logger functionality for real-time monitoring during biotechnological experiments and chemical analysis.

Powered by AA batteries, the PH8500-HT is well-suited for biotechnology researchers focusing on live-cell imaging environments, bioprocessing quality control, and molecular cloning workflows requiring precise pH control under extreme sample conditions. This portable pH meter is widely adopted in laboratories emphasizing synthetic biology research and biopharmaceutical production pipelines, where reliable, high-temperature pH measurement is essential.

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.
