Peristaltic pump SJ-1211H by ATTO with 7–700 mL/h flow rate, max pressure 205.9 kPa, AC100V input
The ATTO SJ-1211H Peristaltic Pump (model 4534-1) is engineered for precise liquid delivery in biotechnology and clinical diagnostics applications. Featuring a single high-flow channel, it supports a flow rate range of 7 to 700 mL/h using tubing with inner diameters between 1mm to 3mm, enabling flexibility for various bioprocessing and molecular diagnostics workflows. The pump delivers a maximum discharge pressure of 205.9 kPa (2.1 kg/cm²), suitable for controlled fluid transfer in pharmaceutical engineering and synthetic biology laboratories. Operated with a standard AC 100V power supply at 50/60 Hz, the compact dimensions (110×150×180 mm) and light weight (2.0 kg) facilitate easy integration into benchtop setups.
This peristaltic pump is critical in biomanufacturing pipelines and gene editing sample preparation, providing reproducible liquid handling essential for live-cell imaging and fluorescence analysis. Note this is a used unit sold as-is, without assurance of maintaining original new product performance, recommended for applications with flexible tolerance for equipment condition.

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.
