Programmable electrophoresis power supply 10–300 V, 4–400 mA, 75 W max with timer and safety features.
The Bio-Rad POWERPAC 200 (model 165-5052) is a programmable electrophoresis power supply extensively used in molecular biology and biotechnology laboratories for gene editing, molecular diagnostics, and bioprocessing applications. It delivers a variable voltage range of 10 to 300 V in 1 V increments and adjustable current from 4 to 400 mA in 1 mA steps, supporting electrophoresis and other bioelectrical workflows with a maximum power output of 75 W. Featuring an automatic crossover function, the instrument seamlessly switches between constant voltage and constant current modes suitable for a variety of experimental protocols.
Key technical features include a fully adjustable timer from 1 minute up to 99 hours 59 minutes, a clear 3-digit LED display for precise monitoring, and four pairs of recessed banana jack output terminals allowing parallel connections. Safety mechanisms incorporate no-load detection, rapid load change recognition, overload and short-circuit protection, and overvoltage prevention to ensure secure operation.
Designed in compliance with EN-61010 and CE safety standards and suitable for typical lab environments at 0–40 °C, this benchtop power supply is optimal for critical electrophoresis workflows in biomedical engineering and synthetic biology research. Its compact dimensions (21 x 24.5 x 6.5 cm) aid integration into laboratory benches with limited space.
This used unit is sold as-is; performance may not fully match a new device but remains a reliable choice for biomanufacturing pipelines, cell imaging research, and essential molecular cloning workflows. Its robust and programmable electrical output makes it widely adopted by research professionals working in clinical diagnostics and biotechnology fields requiring precise electrical control.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
