Watson-Marlow 520Di Programmable Peristaltic Dispensing Pump for Aseptic Fluid Transfer
Product Description
The Watson-Marlow 520Di is a high-precision, programmable peristaltic dispensing pump engineered for aseptic fluid transfer in biotechnology, pharmaceutical, and food processing environments. This benchtop pump features a tactile membrane keypad paired with an alphanumeric LCD, allowing users to program and store up to 50 custom batch routines, ensuring compliance with cGMP and batch record documentation essential for molecular diagnostics and bioprocessing validation protocols.
Key technical features include:
- Dispensing speed of 50 mL in 2 seconds with ±0.5% volumetric accuracy, critical for precise biochemical reagent handling and cell culture media filling.
- Maximum flow rate of 3.5 L/min and pressure tolerance up to 2 bar, suitable for a wide range of fluid viscosities encountered in synthetic biology and biomanufacturing workflows.
- Enclosure options of IP31 (NEMA2) and IP66 (NEMA4X) support lab environments requiring robust contamination control.
- Optional passcode security to lock settings, supporting secure operation in clinical diagnostics and pharmaceutical fill/finish processes.
- Remote operation capability via contact closure or logic input control, facilitating integration in automated bioprocessing systems.
Supporting regulatory compliance, the pump comes with full operating manuals, validation documents including cGMP, IQ/OQ protocols, and maintenance guides, making it a reliable asset in controlled laboratory R&D settings and production pipelines.
This pump is widely used in aseptic filling, cell culture reagent dosing, and biopharmaceutical production, making it an essential instrument in modern biotechnology laboratories, clinical diagnostics, and chemical metering applications requiring high precision and reproducibility.
