Spectrum Labs KrosFlo Peristatic Pump

• Tangential Flow Filtration (TFF) in biopharmaceutical production.
• Cell harvesting and clarification processes.
• Concentration and diafiltration of proteins, viruses, and nanoparticles.
• Pilot-scale and laboratory bioprocessing applications requiring gentle fluid handling.
• Sterile fluid transfer in sensitive applications.

Typical flow rate range

Units of this type commonly offer a wide flow rate range, typically from millilitres to several litres per minute, depending on the pump head and tubing size.

Power supply

For this class of equipment, a standard single-phase electrical supply is common, typically 230V, 50Hz for the UK market.

Pump head type

KrosFlo pumps are typically designed for use with specific pump heads optimised for tangential flow filtration applications, often accommodating multiple tubing channels.

Tubing compatibility

These pumps are designed to operate with various peristaltic tubing materials and sizes, chosen based on chemical compatibility and flow requirements.

Control interface

Units commonly feature a user-friendly control interface, potentially including digital displays and programmable settings for flow rate and pressure.

Footprint

Peristaltic pumps for bioprocessing typically have a compact benchtop design, suitable for laboratory or small-scale production environments.

• What is the primary advantage of a peristaltic pump for TFF?

  Peristaltic pumps offer gentle, low-shear pumping action, which is crucial for maintaining the viability of sensitive biological materials during tangential flow filtration.

• Is this pump suitable for sterile applications?

• What maintenance is typically required for a used peristaltic pump?

• Can this pump handle abrasive fluids?

• What accessories might be needed with this pump?

Peristaltic pumps are valued in laboratory and pharmaceutical settings for their gentle, non-contact fluid handling, making them suitable for delicate samples and sterile applications. When buying used units, buyers typically prioritise checking tubing condition, motor functionality, and calibration history. Industry sentiment favours these pumps for their reliability, low maintenance requirements, and consistent flow rates. Common strengths include versatility across various fluid viscosities and compatibility with corrosive or shear-sensitive media. Prospective buyers should verify spare parts availability for specific models.
