Product description

Multi-output electrophoresis power supply with constant voltage/current modes, RS-232 control, and advanced safety features.

The Lab Companion EP-18 Power Supply is engineered to support electrophoresis and Western blotting workflows in biotechnology and molecular biology research. Designed for simultaneous operation of up to four electrophoresis devices, it features four sets of output terminals to optimize throughput in gene editing, synthetic biology, and molecular diagnostics labs.

Key technical specifications include:

  • Dual operation modes: Constant voltage and constant current to accommodate diverse electrophoretic protocols.
  • Microprocessor-controlled precise electrical output ensures stable experimental conditions critical in bioprocessing and molecular cloning workflows.
  • Stackable design with foldable legs enhances space efficiency and user convenience during live-cell imaging and protein separation procedures.
  • RS-232 PC communication port enables real-time monitoring and control, facilitating integration into laboratory automation systems and biomanufacturing pipelines.
  • Safety mechanisms that include rapid detection of resistance changes and current leakage, over-current/voltage/power protection, and over-temperature shutdown to safeguard sensitive biomolecular samples.
  • Extended timer function up to 99 hours 59 minutes with pause/restart capabilities, allowing precise time-controlled electrophoretic separations.
  • Automatic backup function preserves user settings upon power outage, ensuring reliable reproducibility in clinical diagnostics and synthetic biology applications.

The device is compatible with the LC GreenBox mobile monitoring system (optional accessory), which supports real-time operation tracking for up to four connected devices via internet-enabled app, enhancing remote bioprocess supervision.

The EP-18 is widely adopted in research environments requiring reliable, scalable electrophoresis power control, essential for biotechnology labs focusing on gene editing, protein analysis, and molecular diagnostics. Its multi-channel output and integrated safety features make it a robust option for laboratories aiming to improve throughput and experiment reproducibility in biopharmaceutical production pipelines and cell imaging studies.

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.
