Watson Marlow 505U – Digital Peristaltic Pump

The Watson Marlow 505U Digital Peristaltic Pump is a precision fluid-handling solution engineered for environments where accuracy, sterility, and contamination-free transfer are essential. With its fully digital speed control, intuitive keypad interface, and bright LED display, the 505U offers unmatched reliability and repeatability in liquid transfer. Its peristaltic pumping principle ensures that only the tubing contacts the fluid, safeguarding sample integrity while minimizing maintenance. Compact yet powerful, this system is designed to meet the demanding needs of pharmaceutical production, biotechnology research, chemical analysis, and more.

At HiTechTrader, we make advanced laboratory technology more accessible by providing refurbished and pre-owned equipment that delivers the same trusted performance as new, without the high price tag. The Watson Marlow 505U is an ideal choice for laboratories and production facilities requiring precise flow control, sterile handling, and robust performance in a space-saving benchtop design.
