ATTO SJ-1211L Peristaltic Pump (Model 4534-2) for Low Flow Liquid Delivery

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.
