Product description

Peristaltic pump SJ-1211L by ATTO with 1-channel low flow 7–700 mL/h, max 205.9 kPa discharge pressure.

The ATTO SJ-1211L peristaltic pump (model 4534-2) is designed for precise low flow liquid delivery applications commonly required in biotechnology and molecular diagnostics workflows. Featuring a single flow channel capable of pumping between 7 and 700 mL/h using tubing with inner diameters from 1 to 3 mm, it ensures accurate fluid handling critical for bioprocessing and synthetic biology research. The pump achieves a maximum discharge pressure of 205.9 kPa (2.1 kg/cm²), supporting stable operation under varying backpressure conditions.

Powered by an AC 100V 50/60Hz supply, the compact unit measures 110 mm wide, 150 mm deep, and 180 mm high, with a lightweight design of 2.0 kg, making it suitable for general laboratory benchtop use. This peristaltic pump is instrumental in continuous, contamination-free pumping ideal for sensitive liquid transfers in molecular biology, clinical diagnostics, and biomanufacturing processes where sterile and precise fluid control is essential.

Please note, this listing is for a used unit sold as-is, with no guarantee that it maintains factory new performance specifications. Functionality verification is recommended prior to acceptance. This pump remains a vital instrument for researchers needing reliable liquid delivery in live-cell imaging setups, gene editing protocols, and biopharmaceutical production pipelines.

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.
