Features
The Hoefer SUB20 Maxi-Standard Submarine Gel Electrophoresis Unit is a powerful, large-format system designed to support high-resolution analytical and preparative nucleic acid studies. With a spacious 20 x 20 cm gel tray featuring four comb positions, this unit accommodates up to 168 samples, making it ideal for labs requiring high-throughput and precision in nucleic acid analysis. The SUB20’s versatile design includes multichannel pipette-compatible combs, reducing gel loading time and allowing for efficient sample handling.
Equipped with color-coded, height-adjustable combs, the SUB20 allows easy identification of comb thickness and precise control over well depth. Its buffer recirculation ports, compatible with a peristaltic pump, help maintain buffer pH and prevent ionic gradient formation, ensuring consistent results. The UV-transparent running tray enables safe gel imaging without handling, while colored loading strips simplify well detection during loading. Compact and convenient, the SUB20 features side handles for safe transport around the lab, and casting gates that create a secure, hassle-free seal without the need for tape.

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.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
